Terry, Read about this V912 mod on RC groups. I just did this when I was putting in my new F45 motor. I drilled out the center hole to 1/16 on a V911 tail rotor and mounted it on the motor shaft, zip tied the wires for clearance. Flue the heli , motor is way cool ! I give this a must do. Peace

Hi Terry, I purchased a WL V912 after Xmas and I've been flying it every chance I get and it is fun and I'm a beginner at heli flying I also fly airplanes. I've watched your videos and took your suggestion of cutting away pieces around the motor and add the toggle switch to the radio and it has helped my flying experiences although I did burn up original motor right after I did mod but had extra and replacement was easy. I would like to mention I up graded my lipo battery with a 1300mAh and I get a good 10 min. of flying time which is good for a beginner I also modified the rear vertical tail fin with a 1/6 in. plywood piece I trace out of the original fin and put it on and it has seem to have given it more stability. Well keep up the good works on your videos and HAPPY FLYING

Good video Terry,i just did all these mods-(the plastic above motor and the side metal these are both real good mods ,but i go one further to help cool motor and to extend motor life,which is i put a small drop of oil on the top and botttom of motor shaft every 2 or 3 flights, as i mentioned this will extend motor life as well,thanks for youre video very informative.

hi terry, i have purchased 2 912s and they are great helis for the price. i stumbled across your vids on utube and immediately made this mod to both, needless to say i'm very pleased with these mods they were very simple to make.. i did not use my dremel though i found that a small pair of side cutters works even better, (just make sure not to clip any wires) thanks now i'm a subscriber....

steve vandveer: The V912 flys great out of the box. I did not do these mods until I had over 50 flights on my heli. Get yours have fun and down the road when you get to be a better heli pilot do these mods.

Hi Terry Thank you for all the great info....I have v912 ...new to the hobby and want to do the heat sink mod for the main motor.....is there anything I can do for the tail motor that seems to get real hot also.....thank you again for the great advice Pat ps I been in the air 3 times and it is a blast!!!

Sure thing, I will keep you updated with some comments on this thread if I do pick one up. That said...it would only be in the spring/summer as I am new to RC heli's and still awaiting delivery on my second coaxial (Litehawk XL). The first heli I got is a micro help - 'DFD F103 Avatar', of which I am still training on...lol As for replacing the battery on the BL edition, looks like a major PITA...not exactly user friendly for trips to the park with a couple of spare batteries in-hand. Quite honestly I can't imagine picking one up until they re-design the layout and clean it up a bit. As I noted earlier I really want to see the BL tail rotor also, from what I gather this is a heavy bird which is why the brushed motors burn out so quickly if the heli is being piloted aggressively. Suffice to say I have some serious flight time to log before I am ready to move on to the bigger more nimble birds like the V912 BL. Anyways, thanks for your feedback TBT! Keep up the good work brother, your vids are informative, clear, and appreciated!

steve vandveer: Only problem I had with tail motor is when it went bad and slowed down. I don't know if F645 will fit, I do know lots of the MJX-F45 parts can fit. Just a thought: Make sure your tail blades are not hitting the ground on take off, this is a common problem with the V912. Just add a piece of plastic on the very back down fin on the V912 to keep the blades higher off the ground during take off. When my grass gets very high here I take off from a piece of board so the tail blades do not hit or pick up debris.

Goodmorning from Greece...I hope y r still flying them..I find out that the rear wind of v915 fits at v912...during landing and cruise flight is flying better very steady..special with wind more than 5 meters per second...

do you have a video on how to install the heat sinks?

I got this V912 from a friend, who crashed it, so it was free. The rudder is extremely touchy, just touch the stick and it will spin around. I did get it hovering, so it fly's but the tail is out of control I did the mod and ordered the motor you suggested, also ordered a new main board, thanks too the great price at Banggood it is affordable too try and fix this problem, and get this old bird in the air.

Got my v912 about a week ago and its not going more the half a metre off the ground with a fully charged batter need some help as to why this is happening plz asap thanks

question have you had any issues with the tail motor gear? and the connector buckle hub thats mounted with a screw we have been breaking a lot of them..do you know if the f645 or the f646 parts will fit?

Great vid on some simple mods. I am new to RC Heli's...and absolutely love em'...total blast!! Right now I am learning on a micro coaxial...but plan to upgrade to this bird in the spring! Does anyone know where the heat sinks can purchased for the main (and tail) motors? I found a site that sells heat sinks for the MJX F46...and I am fairly certain they would fit on the V912, but if anyone can confirm it would be appreciated!

Hey there Terry. One thing that occurred to me is that in all the heli mods videos I've seen, nobody seems to point out the longer arms on the swash. Maybe it's just so obvious that it doesn't qualify as a mod (of course I'm the kind of person who didn't notice the turbo button either, so maybe I'm just a little slow on the uptake). All my helis seem to come from the factory hooked up to the shorter arms, so I always end up switching them to the longer arms for more aggressive flight.

Given all the MJX mods would you suggest just buying the F45? I have done the mods to my V912, waiting on doing the transmitter. Thanks great video, I also did the button on top of the flybar.

Please make a video for a V912 brushless mod.

Terry, I don't have the the 912 yet, but it's coming soon, anyways , watching your video , couldn't you have just bent them metal tabs in to touch the motor. I think it would act the same as a heat sink, the hole metal frame is very large , I don't know because I can't see it very well, also the transmitter mod you did on this aircraft turbo switch installation , I'm going to do the same on my V915, I think it's the same, another thing do you have any more mods for the V915, I'm working on a few , but not looking to good, just isn't any room , heat is a big issue on that ship. I'm going to put the esky 370 super motor in , do you have any advice on these items , thankyou ROTOR HEAD FRED

Thanks Terry! Thinking about picking up the V912 brushless...seems to be pretty favourable reviewed...though the ESC is in a real nasty position and tie wrapped right to the LiPo!! How silly...that is a rush design for sure! Not a whole lot room to re-locate it. Also, would be nice if they offered a model that had a brushless tail rotor also. I suspect won't be long before they do, and at the same maybe find a better home for the main ESC. So stupid..that PCB will fail in no time with it sitting in the position its at now, and I am not a fan of fastening it elsewhere because it could impact CG and/or bring about other problems. You planning on picking one up? (V912BL)

Hi Terry always enjoy your video's. Just want too asked about the MJXF 45 motor with a bigger gear on it, will it fit straight in or must you change the gear, it has tooth more, Also I did notice the wire's are reversed on the motor, but the also reversed the wires on the little plug going too the mainboard, so you don't have too do any soldering Looking forward too your Replies

Doesn't that make the wires more exposed to the heat?

Hi Terry, I had this machine as a beginner heli. It flies very fast and had a really nasty crashed. It flew into a bush at high speed. I went ga ga and forgot to close the throttle. It had a burnt smell which l knew it has to be the motor burnt. My fear the board get bad too so went to the hobby shop asking for the board replacement. The guy told me it cost $20 to replace and the heli V912 set with the controller only cost $55. I bought the new set hoping to make as a spares shud the new heli need some parts replacement. I flew my new V912 quite high up about 70 feet up circling my house at high speed. I lost sight as it went behind the trees. Fearing it will fall on the neighbour's cars i brought it further out. Lost control. To my horror the heli landed high speed on the roof of the neighbours about 150 feet away with a very loud thud. I imagine picking up the pieces on the roof and the angry neighbour . As climb up the ladder saw it only broke half of the landing skid and the canopy separated from tne fuselage. The rest ALL intact , the tailboom the rotors bla bla. Put it on the floor and restart and it flew as though as nothing had happen. Highly recommended model to all. A great machine.

i had a couple questions about my v912 first i noticed the tail skipping and it eventually stopped working so it would spin out. i changed the gear and it still spun out. it completely stopped when i was testing it and now won't even bind.

CANANDALINKS98: The V912 is a blast to fly. Its bigger and has few issues but these are easily solved. I have had more fun out of the V912 out side flying than the V911 mainly because of wind. Let me know how you feel about the V912 after a couple flights. Order a extra motor MJX-F45 and when your original V912 motor goes bad install the MJ-F45 the heli will be faster and even more fun. I now have 122 flights on my V912 and its still one of my favorite helis to fly Runways, runways we don't need no stinking runways Tail Boom Terry

Just a small upgrade tip! lose that odd, horizontal whingything on the tail, above the tailstruts. It's useless, and the rotorwash, just pushes it down!! Slightly better performance without it.

Hi Terry, Great job on your videos! I've found them very helpful in learning how to fly and repair my v912. I just replaced my first set of motors and tail gear, after about 30-40 flights. Have you flown the F45 motor long enough to know if it really lasts any longer? I flew most of my flights so far with the stock battery, but I also found a 2200 mah battery that only weighs like 60 grams more than the stock battery. Just strapped it to the belly with rubber bands. I've flown this rig 5 times so far and I really like it. The motor might not like the extra weight, but I think it helps make it a little more stable in the wind too. I haven't pushed the battery yet, but I think I'll get run times of 15-18 min. I saw that Banggood has a brushless kit for the MJX-F45. Do you know if that kit will go in the v912? Seems like it should, since those motors are interchangable. I was thinking I might try that next, if I keep burning up motors. Any thoughts or comments would be appreciated. Thanks! Don

i also have 2 batteries for the v912. I'm thinking i might of over heated the heli

Aaarg! I just learned a hard lesson, but maybe I can spare someone else the pain. I was loading a new battery into my V912 and the white jack of the charging cable bumped the prongs of one of the capacitors where they stick through the bottom of the PCB board. The battery contacts must have lined up just right with the wires from one of the capacitors. A puff of smoke and it was too late. I fried the board. :-( At least Banggood carries the PCB boards in their US warehouse so the replacement will come quickly. My next board is going to get a wrap of tape or heat shrink so I can't accidentally touch those wires that protrude through the bottom of the board. Live and learn...

HI Terry, I have the V912 and after a crash its not charging, the charger is blinking red and the v912 won't charge, do you have any idea what could be wrong?

Just orderd mine ..want to fpv it tho

which would you prefer between 912 and 913

Terry,I think you should add a tail fin upgrade or mod video. The stock is too short.

Hey Terry would you recommend swapping positions of the battery and the pcm(mother board )?

Do you have a linky for the heat sink mods please as i carnt find any on the internet model rc sites CHEERS

Hey Terry. We both share the same first name too. LOL. Anyway, I've been flying radio control aircraft on and off since college and I'm 56 years old. I started with the fixed wing stuff, then got into copters a few years ago. I have several three channel copters and a 6 channel. The 6 channel, quite frankly, is just too hard for me to control. I'm a private pilot too. So, I'm targeting a nice 4 channel I can fly outdoors in my backyard. I've watched several of your videos. I've been looking at the V912 and the double horse 9116.. I'd like to keep the cost sub $100.. Any suggestions on which I should purchase? I know the larger the craft, the better they can handle slight winds.. Thanks...

Hi Terry, how many flights do you have so far with the MJX F45 motor?

As you know the V912 now comes with a brushless motor

What does the button on the right "shoulder" of the TX do? I've never even noticed it before.

Terry, I replaced the motor as you recommended. I also applied a little heat sink grease to the heat sink. I notice that the heat sink does not stay tight against the motor, I get as much as 1/32" gap at front of motor. The temp gets up to 143 DEG on the heat sink both sides of motor and front. I never took a temp on just the new motor by itself. I did all the mods you suggested. Is heat sink suppose to be tight against the motor and if so how to attain that tightness. That aluminum is so thin that I am reluctant to bend it out of the round shape to bring the sides in a little to increase tightness that way. Also I only get 30 yds of distance with radio system yet I have seen other videos of a 912 flying around a field with much distance and speed. Any suggestions would be appreciated. Thank you for your posts of the helicopters and your wife. She is pretty(SMILE).

terry I am new to the RC helicopter seen lol I just got a Egofly LT-711 Hawkspy 3.5CH RC is this one any good and could I do the same modds to it as to the one you got ? I bought it today from a online hobby store online called Hobbystore.com

hola ? alguien me puede ayudar, se me quemo el motor del v912, lo pude remplazar por uno nuevo, lo que paso es q cuando lo voy a iniciar para tomar vuelo el motor esta al mango y yo ni siquiera pude subir la palanca de aceleracion. a alguien le paso ?

terry you think this bird can handle 11.1 v lipo
