Hello Daniel, can you share your settings for scale and 3d flying on the x6 for the k110s?

thank you for watching 🙂

And now I am mounting a TREX 470LP. I am new in helicopters.... is there any placer where I could take an OpenTX configuration for such model? My radio is a Jumper T16 with OpenTX. Thanks!!

As I say in the video, OpenTX university is where I got all my configuration ideas.

Glad you liked it

@@Rchelicopterfun by any chance. How to switch to stab mode and calibrate gyro and accellerometers? Thanks!

I follow the exact same process for ALL collective pitch helicopters.

I have an e160 that I’ve been really struggling with and used these same settings (instead of the 3D ones all over you tube) and now am able to actually fly it a bit. I’m still a complete learner but couldn’t even hover it with the other settings.

Glad you found it helpful

Howdy Nigel, With collective pitch RC helicopters, when most of us reference "flight modes" we are talking about the pitch & throttle curve selections; ie. different collective pitch and throttle ranges in each of the flight modes. These flight mode curve setups can drastically affect how a collective pitch helicopter behaves and ultimately what flying style you can achieve with one. For leaning on, we want a smaller collective range and less power (a tame setup or flight mode in other words). For normal & scale flying, we usually want moderate power and more collective range introducing some negative pitch now but still hovering usually around mid stick. For sport or F3C type flying, we want a symmetrical collective range (equal amount of positive & negative pitch) but not full range and usually not full power. For 3D type flying, we want full power and the maximum symmetrical collective pitch range the helicopter can achieve without bogging down the power or rotor system. All that is selected by the flight mode - what pitch & throttle curves you have programmed for each flight mode. This is different from the "stabilization mode" (the level of electronic self level help offered by the flybarless system/flight controller) which is what you are referring to. Stabilization mode is generally selected by channel 5 on the radio/transmitter for most helicopters and flybarless systems (but it does vary). It essentially turns on a 3 axis accelerometer sensor over the normal 3 axis gyro sensor. That is what I'm recommending to keep turned off (the accelerometer sensor) so you have no artificial self level help (safe, 6G or whatever other marketing term is thrown into the mix) when learning to fly a CP heli. Why turn it off? With a tame "setup" (flight mode selection), most people don't need that artificial self level help because a tame setup will give almost the same tame control response, but unlike artificial self level, will still give you the TRUE FEELING & RESPONSE of a helicopter so you don't have to relearn it all over again when you are ready to progress into more advanced flying. Basically only resorting to self level stabilization activation as a "save" function or if you just can't seem to learn the balancing act of hovering a collective pitch helicopter, even with a tame setup. Hope that helps clear it up & I cover collective pitch setup in much more detail in my setup & tips ebook: www.rchelicopterfun.com/rc-helicopter-tips.html

@@Rchelicopterfun Thank you! Yes that makes sense now and I will get the e-book which sounds like it will help me. I have been trying to join a helicopter club in the UK this year to learn but due to COVID that has not been possible so I am trying to learn myself at the moment. I have the Blade Nano S2 and Spektrum DX8G2. The manuals aren't great to be honest but looking now it looks like F-Mode Setup uses the 3 position switch B which is assigned to channel 5 gear. Positions 1 and 2 must enable safe and position 3 must disable it. As per your recommendation will try to learn in position 3 and tune collective and power. In position 3, 5 point TC all currently set to 100 and PC set to 0/25/50/75/100. Thanks again for your time.

No idea, I would have see it in person.

If you have the Setup & Tips for collective pitch RC helicopter eBook. Throttle hold is covered in detail on page 24-26. Throttle hold is essentially another flight mode that overrides all others so you have a fixed no power throttle curve output and whatever collective range you want for throttle hold. If you need more clarification, contact me on my website as I don't see all you tube comments and reply to even less.

Check and level the swashplate to see if that helps (a little right tilt to the swash is okay to counter the left tail rotor translating tendency - just a smidge. Have you even tried it without the artificial self-level help turn on (ie normal 3 gyro mode)? If it is fine in normal 3 gyro mode, but drifts with the accelerometers turned on, and if you can't successfully calibrate them, then yes, that sounds like a defect issue (if you have confirmed the swashplate is level). With all that said, a nice tame learning to hover/fly setup in normal 3 gyro mode will be almost as easy to fly as if the 6G (self level help) is turned on, and you'll be learning the real feel right off the bat so you won't have to relearn it all over again when you turn self level help off. But do check the swash level since that is key to having a well trimmed bird off the bench.

John Salt thank you so much for your reply I really appreciate it, I’ll give 3D a go next flight and hopefully it doesn’t pull to the left in that mode.

@Mark Linder - you have to mechanically level the swash by pushrod adjustment. Radio trim on FBL should never be used. Some FBL systems without mechanical servo to swash pushrod adjustment (ie. fixed length servo to swash pushrods) will generally have FBL internal servo trim programming to individually adjust each of the 3 eCCPM swash servos to level the arms and get a level swash, but the K110 requires mechanical leveling.

If you have limited toggle switches then combining all DR functions on a single toggle makes perfect sense. X6 is smaller than the TX16s and very different. No idea how much smaller the T12 is than the TX16s.

I would first determine which flybarless system you are getting for a larger heli and then you will narrow the list knowing which RX compatibility the FBL system requires.

Sorry, I will not be supplying model files. As I state on my website, I follow a teach a man/woman to fish philosophy.

@@Rchelicopterfun that is fair enough john. Creates better learning that way. Your videos and ebooks are some of the best help I can find. Much appreciated. If only I lived closer and could have you as a trainer

Thanks for understanding 🙂

flight control board is screwed

No pitch or throttle curves.

@@Rchelicopterfun Thks John, it worked flawlessly. Now, how do you untame this heli. In the original transmitter there is a button to make it fly more agile. Regards

Yep! Anything under a 200 size machine I consider micro. Regardless, CP setup is setup. I setup my 700 & 800 size machines not much differently than my micro sizes for various flying styles.

Thank you.

The iRangeX IRX4+ : www.banggood.com/custlink/mDGGvFWyft I've done a review on it: kzfaq.info/get/bejne/Y96qat2km62RmmQ.html I run it in serial mode: kzfaq.info/get/bejne/jtOFfMd-2KjSin0.html

As I state and demo in the video, I first created two generic heli models (3 if you included the generic Futaba model with ch3 throttle). These 3 generic models are the base foundation for my inputs, mixes, outputs & curves. After that, every new heli model I enter, I will use one of those three models by duplicating it. I then select the model, name it, attach an image file, and go through all the setup steps along with creating logical functions and telemetry setup for the larger birds. In short, every model I have listed in the radio, I created & customized myself, but every one of them is based on one of the 2 generic collective pitch model foundations I first created. It took me over 6 months to slowly switch all my helicopters over to OpenTX & FrSky when I made the switch from JR/Spektrum. Yes, it's a massive undertaking switching systems. I hope I never have to do it again, but in this hobby, that would be unheard of.

Pitch curves set your individual collective ranges for your different flight modes, what I'm doing initially with the +/-12 collective is setting the maximum possible collective range the helicopter can produce.

At that time index (10:05) I'm actually setting the inputs (what stick or switch is assigned to what function). It really makes no difference what order you create your inputs as it has no bearing on channel mapping. I just use the order I'm most familiar with (TAER). Setting your mixing in OpenTX is where you assign your inputs to a specific channel. I go over mixer settings (what channel you map your inputs to starting at time index 14:44. In this particular example as I explain at the beginning due to Futaba's AETR channel mapping (which this specific K110 heli uses), I have throttle assigned to channel 3.

The ESC is what controls the speed of the both main & tail motors; so yes, it's 100% necessary.

Like most micro helis, the Nano CPS SAFE (auto level stabilization) is activated and deactivated through channel 5 output (just like it is on this little XK K110). I believe in the Nano instruction manual for programming, they suggest mixing the channel 5 output to the flight mode toggle so your flight mode toggle is what turns SAFE mode on. If you don't want that function, then you would have to turn that mix off and have channel 5 control through the gear toggle instead.

John Salt ok thanks that’s great. I will have a look and see if I can work that out.

1. Why and physics are covered in detail in my setup and tips eBook: www.rchelicopterfun.com/rc-helicopter-tips.html But the primary reason is gravity. 2. Because all radios used to only have 2 position toggles for that function (thus dual) and the traditional name has stuck even with tri position toggles.

@@Rchelicopterfun Thanks again! Much appreciated. I just ordered the Combo 3 eBook package five minutes ago. Looking forward to reading them!

Appreciate the patronage - happy flights 🙂

Futaba channel mapping order (AETR) - yes it matters.

Yes you can. That's why computerized radios are so important, so you can setup any CP heli correctly & to suit your skill level & flying style.

Look at your channel output monitor and see if you have throttle output on your assigned throttle channel. If not, then you have to start digging through your OpenTx configuration. There are so many ways to alter the outputs on OpenTX after all. Might be something as simple as not low enough throttle signal to arm the esc or throttle signal is backwards. Lots of other possibilities of course.

I don't understand what you are asking about "setting". What setting? If you are referencing collective pitch RC helicopter setup, size of the helicopter is irrelevant. You setup a collective pitch RC helicopter to produce the amount of performance you want out of it based on how you want it to behave & your flying style/experience level. As I say in the video - that is the fundamental constant for all collective pitch RC helicopters regardless of size, brand, or power type. www.rchelicopterfun.com/rc-helicopter-tips.html

I'm not a Rotor Flight user. I fly Bavarian Demon and Ikon mostly plus it's a big time investment in learning, getting used to and fully trusting a new system. With that said, I'm interested in trying the new RadioMaster Nexus which as you likely know runs on RotorFlight, but it at least has been properly tested and tuned by others as I have no time nor desire to beta-test open-source unknowns, so we will see what the future holds. Jonas of course has already done a full Nexus configuration video which I can't hold a candle to.

Not sure I understand your question "setup the collective pitch." Collective pitch setup starts at 17:06. If you are asking about an eCCPM (electronic-cyclic-collective-pitch-mixing) setup, like almost all flybarless RC helicopters, the K110's flybarless system (flight controller if you prefer) does the 120 degree 3 servo eCCPM mixing internally. There is no radio eCCPM mixing required. Just that you setup your collective channel output (ch 6 in this case) with your various pitch curves. Only if had a heli that didn't do the swash mixing via the flybarless system (Align 3G or 3GX for example) or any flybared 120 degree eCCPM heli, would you have to enable internal radio eCCPM mixing, and that would be done in the heli setup menu on the radio to select an internal radio eCCPM swash mix program.

@@Rchelicopterfun thanks, you've answered my question.

Pretty much. Like most traditional collective pitch RC heli setups, I use a 3 position toggle to set my 3 separate pitch and throttle curves for my 3 flight modes (plus a separate hold throttle & pitch curve) which naturally overrides any of the others when I engage throttle hold. As for dual & expo rates, I personally like having a separate cyclic dual rate toggle and rudder dual rate toggle and use two more toggles for them. With OpenTX (and most other computerized radio OS systems), all the dual rates could of course be coupled to the same toggle as the flight modes so it's all controlled from a single toggle for those that find that easier. I just like having the ability to separate my dual & expo selection from my pitch & throttle curve selection, especially for scale or F3C type flying.

@@Rchelicopterfun Thks, John, great explanation. I was wondering about using the potential of Open TX, but you explained it very well. Regards

I would really have to see it first hand to correctly diagnose; but it sounds like the servo arm on the servo in question has likely cammed out one or perhaps more spline places on the servo output shaft. A servo gear could also be stripped in that servo causing it to jump out of position. Just guess of course without seeing it first hand.

@TechNoPhobia - There are no remote gain adjustments on the K110. Like most modern day micro size FBL collective pitch RC helicopters, channel 5 only controls the mode of stabilization. Either normal 3 axis gyro mode selected, or self level mode activated. Basically a this or that selection with anything from about 0% to -100% travel output putting it in one mode, 0% to +100% travel output in the other mode. *No gain adjustment at all.* There is no LED color change or flash sequence on any of the XK helicopters to indicate which stabilization mode you have selected. However, like any FBL unit that also has a self level mode, it's pretty easy to visually determine by swashplate tilt behavior what mode is selected. In self level, the swash will generally stay tilted after a cyclic command or heli movement. Whereas in normal gyro mode, the swash will slowly level back out after a cyclic command or heli movement. Or just hover the thing to feel what stabilization mode it's in as it's pretty obvious. 🙂 If you are not getting a mode change by channel 5 activation, you'll have to confirm on your radio (servo/channel output monitor screen) you are getting full channel 5 travel in both directions with whatever toggle/activation method you have selected to control channel 5. If you are not seeing any channel 5 control, you'll have to recheck your channel 5 input/mix/output programming setup. I know of know way to electronically level the servo arms on the XK micro helis. I've always made adjustments mechanically if required to trim them out (in normal gyro mode). Mechanical adjustment procedure is the same as it is on any RC heli... first servo arm spline selection to get the arm as close as possible to a level position, then pushrod ball link threading adjustment to level the swash.

@@Rchelicopterfun Wow! Thx a million for the QUICK, detailed reply! My swash doesn't react like yours in the vid to indicate EITHER gyro mode. When I tilt the heli, the swash stays put (maybe I'm not 'doing it right'???). I'm using the SB switch and, yes, channel 5 is indicating -100, 0, 100 output in the monitor. Dunno what I've done wrong. I don't want to do a test flight because I CAN NOT fly without stabilization. Period! I'm used to fly bar helis that 'self-level' (in normal flight mode, I guess) when the cyclic stick is centred. These FBL helis that stay in one position when the stick is centred are beyond my control! I just crashed my brand new E160 when I switched it into 3D cuz I couldn't friggin' KEEP it level. It was BONKERS! I also had 100% travel and no EXPO tho, which was an oversight in the heat of the moment! If I'd reduced the travel, I MIGHT have regained control. We'll NEVER KNOW!

@@Rchelicopterfun So I flew my K110 last night and everything seemed to be OK ... sort of. Didn't have enough collective range so the bird didn't want to climb, especially in normal mode. Increased that and it was MUCH better. As far as the tail goes: NOT enough gain! There HAS TO BE a way to increase the gain on the gyro using OpenTX! Using the XK X6 radio, the tail is LOCKED IN ... BEAUTIFUL! Using the TX16S, the tail is pretty bad. I noticed it RIGHT AWAY! Even just taking off, the tail was drifting left, which it NEVER did using the X6. The X6 gains are set at 75 and 25 FOR A REASON. They're not set at 0 and 100. Using the TX16S, the gains are set at 0 and 100, effectively. There has to be a way to set them at 25, 75 using OpenTX. I'm REALLY surprised you said in your review that the tail was "locked in" using OpenTX; that certainly wasn't the case in MY experience. In fact, the tail was SO NOT locked in that I immediately considered going back to the X6 radio to fly THAT model. I totally trust and respect your advice/opinions, but my experience was totally different than yours with this model. I'm probably doing something wrong.

I simply created those extra categories (same thing as creating extra file folders). In openTX in the select model menu, there are 6 options: Create model, duplicate model, move model, create category, rename category, delete category. It's that simple.

I perform all radio programming for all my models with the radio alone. That is the benefit after all of a computerized radio - direct programming without the hassle & complexities of external devices. 🙂

@@Rchelicopterfun John, thank you for that, and for the " Salt University" here on You Tube. It's the reason I bought a Horus 12, and numerous other suggestions. Stay Well!

Yep, a misspoken blunder on my part. The collective range in that example pitch curve is 0 degrees at low stick, about +4.5 at mid, and +9 at high.

@@Rchelicopterfun John, I am trying to understand why you use that curve, instead of keeping zero degrees at midstick, similar to idle up 1 and 2

Sorry, I don't share my files. Why? #1 & main reason... It would not be fair to all my customers who paid for my collective pitch setup & tips ebook & my setup help over the years.

Not a single one confirmed the mechanical setup of their heli and then adjusted the outputs according so the collective range and the symmetry of their collective range would then be correct for proper pitch angle. These are not mechanically simplistic quad copters after all; every single collective pitch RC helicopter has mechanical variation - even the exact same RTF models. The result of all this... A crash on first spool up, and I get blamed for it because they didn't understand the basics of collective pitch setup. Never again.

Howdy Barrett. Yes, I physically swapped my rear toggle switches around so the sprung momentary is on the left and the normal two position on the right (like I'm used to all on my previous radios over the past 30 years). So what you did there by using the SF toggle on the left for your throttle hold activation is spot on correct. The next statement however "the heli will not spool up in hold mode now"... I don't see any problem with since that is the whole idea of having throttle hold turned on - the heli won't power up when hold is engaged. So I need clarification on that because it's working exactly the way it should. If something isn't working correctly however, use your channel monitor screen to help fault trace. As I so often say, it's one of the most important tools that computerized radios give us to help figure programming issues out.

@@Rchelicopterfun Thanks for the quick response John. No issues with function of hold mode. I could have stated that better about the spooling. Thanks for clarification. Respectfully, Barrett

Awesome 👍

Good eye! It was my mistake. I must have deleted that specific switch position by accident as it was in there initially. It still works fine of course since there is no other switch option there so in normal mode, it just defaults to the normal throttle curve. But yes, it should have shown the SE toggle with arrow pointed up just as it shows for channel 6 normal pitch curve selection 6 lines below.

@@Rchelicopterfun Thks.

thanks, will check it out.

Opentx uses positive expo to shallow out the output just like JR/spektrum. Not like Futaba.

thank you sir! good to know!

Never said that...

@Peter Cane - I'm not sure what "heli icon" you are referencing? If it's the little red circle shown in the model setup screen (a little airplane shown in this video), it really has nothing to do with radio outputs since we are programming those anyway. You do have to have the "no heli" box unchecked however in the build options so you can activate CCPM swash mixing type for helicopters that require internal radio CCPM mixing. By the way, flybar or flybarless has no impact on type of CCPM selection, it has to do with where the swash mixing occurs (externally in the helicopter or internally in the radio system). You can have external swashplate mixing on both flybarless (most of todays FBL systems do the CCMP mixing) or old mechanically mixed flybared helicopters (swash mixing is done on the heli mechanically). Likewise, you can have internal radio swash mixing with flybared helis that don't use mechanical mixing or some FBL systems like the Align 3G & 3GX that don't do any swash mixing within the units. I cover all this in two separate videos I made on OpenTX for helicopters. Part 1 - No radio CCPM mixing (external mix): kzfaq.info/get/bejne/jsp2gtGVta2bqKM.html Part 2 - Internal radio CCPM mixing: kzfaq.info/get/bejne/d8d-q5BpmL2ulZs.html Hope that helps...

@@Rchelicopterfun Thanks John. Yes that helps a lot. Yes I mean the H icon in a circle on the Tx menu. Second icon along from the left.

@Peter Cane, the H submenu is used for swash mixing programming. It's only used with internal radio CCPM swash mixing, not external mixing which is why it wasn't used on this K110 heli example since the FBL system in the heli does the CCPM mixing. I cover using that H submenu in that second OpenTX heli video I mentioned above (internal radio CCPM).

@@Rchelicopterfun Okay John bear with me I am an old noob!!! I have to set financial limits to my new obsession so I limit t my helis to very small ones. I have two S3s, an XK K110 in the post and I look forward to getting an OMP Hobby M2 Explore. So these three already have internal mixing and do not require the H icon but Noheli left unchecked yes? On the newest open tx SD card firmware version there is no Heli wizard. Is this right? There are quite a few of us that are experiencing difficulty setting up an S3 with a T16S and most describe it as " Tricky". I went out and bought a DX6E to do it but its niggling me that I cannot do it with a T16S. Would you be kind enough to do a vid on this ? Thanks John for getting back to me. You deffo know what you are doing so I will copy you. Making a training skid but I have to think hard where to get the balls. Thats half the fun. Peter

@Peter Cane - Sorry, I don't know what a heli setup wizard is on OpenTX? There never was one that I know of since using OpenTX from 2017 onwards. I've always used OpenTX University's base template which is what I show in those two videos and I use it on every collective pitch heli I own from little micros up to 820 size turbine. The Nano S3 would be setup identically as well. I don't have an S3 to do a video on one, but again, it would be identical to any other collective pitch helicopter setup. The only difference with it over this K110 example would be it uses Spektrum channel mapping order (TAER) instead of Futaba order (AETR). I even go over that in the second video above where I discuss creating additional OpenTX templates (4 in total) so you are covered for both Spektrum & Futaba channel mapping for both external & internal CCPM. As you'll see in that first OpenTX for helis video (external radio mixing), you don't necessarily have to uncheck no heli in the build options if you are only going to have/setup/fly externally mixed CCPM RC helicopters (such as all the ones you have listed). All the no heli box option does is remove that swash mix sub-menu from the list. However & as I point out in that first video, it's generally in your best interest to have that swashplate mix menu in your base heli template for if/when you may get a heli/s that require internal radio swash mixing. In other words, it somewhat future proofs your base OpenTX heli template.

It depends on the flybarless system. With most higher end FBL systems you set the max cyclic travel in the FBL unit. Other basic FBL units, yes, you can limit the travel outputs in the radio for the cyclic travel on pitch & roll channels (elevator & aileron).

@@Rchelicopterfun thanks John. So this is with the OMP explore. I've had to order the M2V2 as I could not fix the issue with the explores tail not holding and blowing through motors. Disappointing but hoping for better luck with the new one.

Sorry, I don't know a thing about that model.

@@Rchelicopterfun That is the new Scaler from FlyWingrc a Bell 206 with H1 installed

Yes OpenTX can control a normal eCCPM heli. It will allow 120 degree mixing within the radio for traditional flybared machines or ones using flybarless systems that don't do the 120 mixing internally. Now I'm still running 2.3.9 but there is no reasons things will have changed in 2.3.10. They haven't changed yet in countless updates after all. I won't of course know for 100% sure until I update, and I always wait a good month or two before doing that in the off chance there is a bug in the new release. I have several fly-bared machines with 120 eCCPM and several more that use Align's 3G & 3GX flybarless systems (electric & nitro) - all working fine with OpenTX . You of course have to make sure you have the heli option enabled in the Companion build options for the radio so you can select the different swash mix types in that menu.

@@Rchelicopterfun John, thks for your fast answer. I indeed watched your video regarding throttle trim with much interest. I am not quite satisfied with the way it tries to solve the problem, mostly because it would still affect channel 6 in pitch control. Regards

Not sure what is lacking or how it would effect CH 6's mixing outputs? Everything works perfectly as it should on all my 120 degree eCCPM mixed helis in OpenTX, just as they did when I was flying them with pre-configured computerized radios. One crucial & important item however is to make sure you set your dual & expo rates on the input side as I show in this video. This is discussed in OpenTX University in the helicopter setup section: open-txu.org/home/special-interests/helicopter/heli-part-1-setup/ It specifically states: "Dual Rates and Expo - Next step is to change DR and expo for the Aileron, Elevator and Rudder. This could be done in the mixes, but the best place is in the inputs. The reason for this is that if CCPM were ever to be used, the CCPM mixing is done directly from the inputs, not the mixes.

@@Rchelicopterfun Craig Oakley mentioned in part "CCPM for Taranis": You may also notice I have NoTrim for the collective inputs. This prevents any trim entered by the trim added through the throttle trim tab from affecting collective. I also do the same for throttle. This will come in more important in the lesson on internal combustion (Nitro) helicopter setup.

Yes, I totally forgot about the throttle stick trim issue (it's been 4 years since I converted the entire fleet over to OpenTX). On my one remaining nitro heli, I use the same throttle servo/idle control method I show in that gas airplane video with the idle control S1 dial add multiplex function on the CH1 (the throttle channel) mix side so it has no effect the collective output when using it. I just looked in my radio at that model, and the trim box is also turned off on throttle stick input setup screen so it doesn't impact collective output if I accidently use trim on that stick. I never touch that trim no matter what I fly, so I guess I pretty much forgot about it - out of mind out of sight kinda thing - lol.

It just my preferred method of toggle position when I'm in low or high rates. In low I want my upper toggle (SG) to be in the rearward position and my front toggle (SD) to be in the down position.

@@Rchelicopterfun Ok, thank you again for your patience. You relay very much in your memory to remember that!!! For me, it would be simpler to uniform the action of all switches. Regards

Back in the day before computerized radio', all dual rates selections were default to those positions that I use. That subconscious memory after close to 40 years of RC flying is not easy to change - why it makes sense to me. Of course, that is the beauty & power of computerized radios, we can configure them any way we want.

Program them yourself to match the mechanical setup of the heli, your skill level & your flying style. That is the only way to have a properly setup collective pitch RC helicopter.

Nose-in orientation doesn't change a thing on the heli, so no idea there other than normal lean caused by tail rotor translating tendency that perhaps you don't notice as much when it's pointing tail in.

@@Rchelicopterfun thanks a lot sir 🙂

FBL stabilization selection is controlled by channel 5 (on most micro helis), so you would set your channel 5 output however you want to change it from -100% to +100% such as a toggle switch.

@@Rchelicopterfun thank you man

This video addressed the radio and helicopter setup portion of RC helicopter setup. That is different from the flybarless system configuration & setup. Regardless of what flybarless unit is used or even if it's a mechanically stabilized helicopter (flybar), collective pitch RC helicopter is very much universal and all these same steps I show with this little micro CP heli are done with all sizes. As for flybarless system setup & configuration (RX connectivity type, servo travels, centering, pulse width, gains, travel limits, gyro direction, swash leveling, piro-comp, etc.), that is unique to each flybarless system and the best tool you have for that is the flybarless system's setup wizard.

I'm presuming by "hands off" you are referencing "auto level" or as XK's marketing calls it, 6G? If so, I go over that in the video when talking about the output of Chanel 5. Ch5 travel output in one direction activates accelerometer stabilization, in the other, normal gyro stabilization. I also explain how to confirm it's either turned on or off by watching the swashplate behavior since XK's heli don't show it by LED color like some other brands do. Of course there is really no such thing as a long duration "hands off hover" with any single rotor micro CP heli; you still have make corrections regardless as hover equilibrium is easily disturbed by even the lightest breeze or the little heli flying into its own dirty air. As for cyclic response to be more scale like, just keep dialing down your cyclic dual rate values until you get them to a point where you feel you have a good compromise between control and reaction/response speed. Keep in mind however there is only so much that can be done with small micros that have next to no mass. Micro's will never have the awesome fluid flight characteristics and rock solid feel of a larger CP heli that is required to mimic scale helicopter behavior.

@@Rchelicopterfun , U made a video of XK 123 and 124 taking into CALIBRATION mode, but one did not go due to unknown reason. Yes 👍 I meant HANDS OFF hover in 6G mode, at least couple of seconds. Basically fine tune 🎵 the accelerometer that all I wish to know. If u could kindly make a video plsssssss . 😊😊 As dor th cyclick response , my other micro such as Mcpx Bl has tht type of STICKY , GLUEI type tht makes thr hover so stable. I just feel XK swash is twichy , thts the problem. Thanks.

@@Rchelicopterfun , Ok 👌 I don't need to do CALIBRATION in 6G(3d) mode as it is already very very stable & can be as HANDS OFF for couple of seconds . But in the 6G mode it is pulling to the left fast and cyclick compensation needed to hold. Swash is all leveled . Smethng to do wth ACCELEROMETER . Would u pls help if a video possible 😊 Thanks .

Collective pitch setup is universal. The basics are no difference.

Bro u can't set up that wltoys shit

Just cut it from a thin piece of cardboard, but any similar material will work. It's covered in chapter 3 (micro cp setup) of the setup & tips for collective pitch RC helicopters if you have that eBook already: www.rchelicopterfun.com/rc-helicopter-tips.html

@@Rchelicopterfun thanks ill order all 3 tonight after work

Not very :)

Keep it up sir I like your content. I have WLtoy helicopter thanks for information you've shared.. ❤️ from Philippines keep safe from Covid 19
