Being from Holland I am considering using a wooden shoe for a copter.

What a luxury to have all that space to work with :)

The antennas with the lump in them are sleeved dipoles and yes, they have a slightly higher gain than a simple 1/4 wave whip but more importantly, they have a more even radiation pattern so there are fewer null points and thus the range will be more consistent with varying orientation.

sorry guys, my english is not really good. I have not understand if stock x6b antenna are better than aftermarket antenna.

Interesting stuff, I too tested four alternative antenna types with this receiver, mainly in an attempt to get the antennas outside my plane fuse, those stock originals being very short. In the results at 300m range set across my property clear run, I got a base line reading of -74db using the originals, however I got nothing better than -78 with all others, including gp monopoles, 33mm element 130mm wire monopoles, frsky tx antennas and a long set of gp monopoles (180mm). The worst reading being with these at -86db. I then tried trimming the 130mm wire dipoles to exactly 23mm element length, but could only get -79db, I then cut the total length to match the flysky originals with 33mm element and got 81db, trimming back to 23 still couldn't match originals at -75db despite now looking identical. I then repeated all the tests to confirm everything, I used a jig at each end to replicate exact positioning. Here's the witchcraft bit, i also tested an alternative course through trees but with two types only, the originals and the 130mm wire dipoles @33mm element, and the originals were now worse than the 33mm ones by 4db at 100 metres through 12 fully grown, full foliage birch trees in a row... very strange, it was this that made me repeat all the tests, but just inexplicable. Anyway, whatever magic they are using to get such amazing performance from what appear to be incorrectly tuned antennas (except for tree penetration) is anybodies guess, just don't try to make your own replacements :( Apologies for the rant, but as always you presented another great video and with interesting results.

love your wooden quads. havent seen one on this channel for a long time!

No way to avoid subbing... I'm looking at your videos page. You're a hero.

There must be something wrong with that helical -- you should have seen a much better improvement with that than with the skew-planar. Is it an Aomway helical by any chance?

Impressive, both the wooden frame & the farm : )

bulky bit on the antenna is a 1/4 wave sleeve balun, used because coaxial cable is unbalanced but the antenna is balanced; the choke stops the shield of the coax radiating.

External smd attenuators are great for range testing when there is no option for lowering power, assuming you have a transmitter that has an external antenna socket in the first place. Inconclusive test is also a good test. I think 2.3km is enough for most typical uses, especially in countries that require line of site.

Dude your drone is impressive

I'm impressed. that thing can fly!

Omg the og versacopter! And a yi n that's dope! Old skool!

2.2km with the original transmitter? Or you have modifications on it? best regards

antenna theory is verging on the mystical... the dipole ones usually have less than the quarter wavelength 31.25mm because of the speed of light travelling down the wire....... i stopped listening there and wished i hadn't asked..., the 23mm made me worry it was supposed to be dipole but didnt get the little bullet casing part put on... the 33mm threw out all previous theories because its too long.... and remember, you do the walk of shame, so we don't have to.

great video, till valid in 2021

impressive drone

Hi ,please make video about the frame...

thank you for all vids. Sure, you are right with antenna. The better is the strongest one. It's called in French: "Antenne a jupe". I just tested one of them with a vector analyser. It match perfect at 2.4GHz return loss is about -20dB witch is perfect. These kind of antenna doesn't require groud plane. it's is not the same for a quater wave antenna, to have a good return loss, they need ground plane. And... there is no ground plane at the end of a coaxial cable ! So I'm sure that these antenna are... BAD ! regards

Iforce2D: I see that you have marked your mounting block for a 2nd camera, and I remember that you were intending to explore binocular virtual reality video in a previous YT video. Did you ever follow up on that? I'd love to see the details!! - Jim

2km? jezz that really nice for a 40-50$ radio

hello, good information. im just a little confused about my drone (wizard x220s- ATF) i bought the RC, battery, charger. but i dnt know how "bind it" with RC and receiver, I dont know if im missing cables for it..??? also i have this three little wires coming out from my drone, for what it is? (White,yellow, black) is for connect it into my receiver. PLZ ANYONE HELP ME! IM NEW IN THIS

Nice video !! What FC are you using for RTH ? Thanks !

Hey bro, how to setup your flysky i6x with x6b connect to your drone??can you make a video about that.. Thanks

Hi iForce, is it hard/expensive setting up a quad like yours? With gps barometer etc?. Good video btw

The x6b receiver, did you use pwm or ppm? in the description in BG I saw failsafe is only available in pwm mode?

nice review, thank you. Also you got some very beautiful land to fly on. Do you own that?

Love this video. I used to make prototypes for 12GHz things and I am skeptical about the cavity enclosure they put up on the x6b, and I worry if that only adds weight for my 2 once craft. The cavity seems to be suitable for 5GHz things.

Stock FlySky FS-i6X + X6B 1.5+KM range? that in nice actually

The 23mm should be correct length for the 2.4 band, if you vary from that it can go wonky. My guess is it one were to trim 33mm lengths to 23mm you would have better results. It all has to do with wavelength.

well done sir

I think the optimal length for the exposed part of the wire is 31mm for 2.4ghz. I also have been wondering why the FlySky receivers have varying lengths shorter than 31mm. The lengths are not consistent. On all my FrSky receivers the lengths are very consistent and in the range of 31mm so I'm not sure what's going on...

Hi. Sorry for commenting on an old video, but I have a nice question. Have you used FS-i6X or the old FS-i6X as transmitter? At 11:20 you are using the old one to check failsafe :)

Could you get the last stage of the failsafe to cut the motors ? with some sort of impact detection routine.

how heavy is your drone/quad. it looks really heavy to me. You must have a very strong battery and motor setup?

What software did you use in flight controller? Good test :)

The real conclusion i see here, is that this helical antenna is absolutly not working better than the usual one, no ? Still amazed by the range you can have on a stock Radio

Hello, I have the X6b receiver and the flysky i6x transmitter, and when I am at 300 m. the RSSI signal is less than 25%. Can you tell me please what am I doing wrong? Thanks.

what flight controler did you use for this quad?

What kind of GPS are you using? How does the quad hover so well?

wow a mile and a half is so far. cant wait to fly mine super far. Is a lower C rating better for a longer, endurance flight?

Could you tell me what gps module is best for the flip 32 without taking off the board compass ? Also can you tell me what’s firmware you run ? Inav ??

Is there are video which shows how to connect x6b to the flight controllers?

Hi! I bought and FS-I6X but i'm unable to set Failsafe on INAV. Can you explain me how to do it? Thanks!

Hi, I have a question that you may or may not be able to answer. I bought the KingKong 210gt and it came with a FlySky i6 and the ia6 receiver. I want to upgrade it to get better range. I don't know if I should get the ia6b or the new x6b. I've heard i.bus and s.bus are better connections than the pwm that comes setup already, but I am not sure if I can use i.bus. The FC is the KingKong f3 micro one. hobbyking.com/en_us/micro-f3.html and the manual says it supports s.bus. Does that mean it should also support i.bus? Thanks for any help you have.

What helical antenna are you using and do you like the range? I use a Diversity receiver and I want to order a decent helical. Thanks

Hello, do you have a video talking about bluetooth + flight controller and cell phone communication? Thank for the video =)

Hi. Interesting vidéo for FlySky part, ans also jour DIY quad simply made with wood parts. I'm interested with you GPS. Do you use BetaFlight or iNav ? I could you drive well the RTH mode, and may be the switch between the GPS mode, and the manual mode. I have also the FSi6 and is it easy to watch telemetry informations on the RC screen. Or do you use the OSD on your video receipter ? Regards.

Hello. I am using some 1 mm steel wire to hold the antennas in position like yours but there are not long to overlap the tip where the wire is exposed. Do you think this affects the signal? I cannot go further than 300 meters and i reach alarm of 15 dB.

Where did you get the RTH/GPS module? please & thank you

Interesting - am now considering FlySky FS-i6X Tx Bit of a naughty Q... was looking at a Taranis but the FS-i6X being £100 cheaper has me a thinking so which one do you think...joe

From their respective spec sheets : Ia6b rx sensitivity -105dbm X6b rx sensitivity -95dbm Does it mean ia6b should have the advantage?

could use some data on the turnigy ia6c and the evolution if anybody from hobbyking is watching.

iforce2d -- which one is better between T6 and i6x, bro..?

what is board control ? is f3 full sensor ?

Have you tired the x6b on true dipoles like the ia6b comes with? In a foam board plane I'm building at the moment and I'm going to be trying out the x6b with the true dipoles that are fitted Inside the i6 and i10 transmitters, both my transmitters have been converted to sma sockets so have the stock internal antennas kicking about. Only ever flown on the ia6b till now so interested to see what range I get from the configuration I'm going to be using. I dont know if it's an error on the paper specs or not but the x6b appears to have a lower sensitivity than the ia6b.

so which is better an 23mm or 33mm antenna? you went 2.2km with both

Nice! But why don't you just use carbon frame?

Which replacement antennas did you order? could you provide a link? i mistakenly ordered 5 replacement antennas for an frsky receiver thinking they would fit.

How i can build like this quadcoper wood ,

I dont get it so what was the longest range?

what flight controller and GPS ?

You are using pwm protocol right

Hi, at 1:52 you mentioned the 23mm antennas vs. the 33mm antennas. The 23mm is closer to the length used for a 2.4ghz radio system (+/- 26mm). Personally, I like to make my 2.4g antennas with 25mm pole lengths for better tx and rx across the 2.4 band. Check out IBCrazy's calculations on RCGroups: www.rcgroups.com/forums/showthread.php?1388264-Build-IBCrazy-s-Cloverleaf-The-ultimate-circularly-polarized-aerial-antenna! All the best and Happy flying!

2.3km its video transmitter range, so we still don`t know x6b range?

wow fpv drones have come a long way hahaha

Hello, 33mm is far too long, more than a quarter wave. To put some light on this for those who are interested, please read on at these two links. 1. post two... www.rcgroups.com/forums/showthread.php?t=1516397 2, and the basics.... www.rcgroups.com/forums/showthread.php?t=2371720 Hope this will help to find the correct length for your antennas. I am very pleased with your way of testing the stuff. Keep on , thanks a lot.

Hello, I got to say, I love your video!I am wondering if you could please help me?I bought x6b and skyline32 advance. I am hoping once I have successfully connected the fc to the receiver I will be purchasing a gps module. Now however I am struggling to connect the receiver to the fc?Could you please help?Many thanks

Thanks for doing the flight range tests. 16:44 doesn't the I6X TX have a range test switch to attenuate the output signal for ground range walk testing ?? If it does... you could test the 2 RX to max ground range.

frame size 300mm? prop size and motor kv please?

i wish my country had all the rc stuff Too! :(

what power boscam video tx are you using?

so the conclusion? ia6b better than x6b?

Do you have the link for that antennas?

can plz test the range of this old transmitter flysky fs-ct6b-6

Which propellers did you use?

What OSD were you using?

Thanks for all the great videos. I'm trying to set up INAV failsafe return to home as you have done, but it's not working. I've the fs-i6 transmitter. Any suggestions?

What firmware is used in the flight controller?

You could've used normal props as bullnose props sucks economy..

Hi, first of all, thanks for nicely done and very informative video. It's nice to see a high quality material among all the underage morons shouting out their opinions on the internet. Yours - a pleasure to watch. But to the point - I'm very new to all this drone fun, just planning to build my first one. I want to create something small, but full of features. So it will be mini quad frame, but it's going to be more of a fun-testing-ground machine than a racer. Oh, and unfortunately ona budget too. I've been thinking about FS-I6X transmitter, but most of them are sold by chinese with x6b receiver. Will I be able to send telemetry back to the receiver with x6b, or do I need ia6b? Actually I like ia6b form factor more, the case seem to be more study than a naked pcb. You seem to be pretty proficient with all these drone stuff, would you mind being nagged by a newbie a little bit? I'm struggling with existential dilemmas choosing parts... .) Maybe you could advise: www.rcgroups.com/forums/showthread.php?2809492-PDB-LC-filter-or-not

this video hoax. it blogged about fs-i6x with x6b. during a flight on the videos I see fs-i6. a simple antenna can overcome the distance 2.3km
