ok nevermind.....i got the rotors to turn but it looses contact with the t.x sometimes and does w.e it wants. could this have somthin to do with the low tx batteries or the antenna not properly ran.. cause right now my antenna is wrapped around the skids....should it be out the back in a tube??

On one occasion when I first got it, was running it up in my lounge and it seemed to loose cotact with the transmitter and went crazy (resulting in loosing my first tail gear, shaft and tail blade carrier) and had to stop it by pulling the plug, otherwise it was fine. These things seem to be notorious for dodgy electronics though.

Status: offline 		Hanney 12c or above and for longer flight a 1500mAh or above. The 12c will have plenty of Amps to spin your motor even at 12c 1500mAh gives you a continous 18 Amps which is plenty for the 35. I run 12c 2200mAh and get almost 18mins of hover time on mine. Good luck

Status: offline 		Hello. i am new at the mini heli thing . just got the wakera dragonfly #36. watched battery charge, plug into heli test servos (all work) , but the blades don't spin. it just beeps, and has a constant red light on gyro. the light blinks when i move the servos, but can't get to "start". i checked to see if stuck or tight , but spin loose, just no power?

sorry if bit mumbly, but work all day come home to try new toy and just watch the servos move back and forth, sad.


lipo batt 1800mah (2), brushless, train kit(how it goes on i dunno), extra blades.

Status: offline 		iamnew, Does the receiver light flash or is it on steady? It should be on steady. If it is flashing, it means the receiver (rx) is not receiving a signal from the transmitter (tx). Chech that your transmitter is on. The bar scale on the tx should light all the way to green. You might have to move the rx antenna wire to get a better reception. Try to keep it away from other wires. They can cause interference with the radio. Check your motor connections. Also FYI, there is another thread that deals with the 36 exclusively. (Walkera #36) It is a long thread, 157 pages at present. Scan through the pages from page 1. Along the way you will find some detailed setup procedures. The heli needs to be set up properly before you begin to think of flying it. It is very important. Don't skip it. The radio as well as the mechanics of the heli need to be set up properly.

Status: offline 		loosesned motor from main gear, spin up. but when i tried to get it to just hover a few inches one of the control arms (automotive term yes but same thing) came loose went side ways and broke a blade and stripped the gear.

sorry.... it was ready fine just gear too tight as mentioned above ( up in page not my post, must have over looked).

so now i order a gear and control arm linkage thing. do they make them in cnc aluminum for this heli? that would be the way to go.

ps even though it crashed, not entirly my fault, it was fun to hear it scream!

A bit more info is needed to help you out. Are you running a brushless motor with an ESC or are you running the stock motor? You're Lipo I am assuming has a Deans connector on it.

Mabe someone can help me, I have a 35 and cannot get enough head spin to get this thing to fly, I have changed Lipos, used NICADs NIMHs everything but still cannot get this thing to take oof and when it does, its soo unstable due to the low head spin and high pitch that its twitchy and always crashes.... the only way to get it up is to increase the pitch and that lasts for under 1min.... What I have changes, used batteries of all sorts, what should I try ?? I just got a GWS esc and will remove that crap esc from the receiver, do you guys think my engine is busted ?? I have measured the amps and the maximum drain I get is around 7A.... either its the esc, or the damn engine..... Any thoughts ??

cosmospho, Do you have a brushless motor? I have an Align 430L 3550KV/ 35A ESC combo that works quite well. The head speed needs to be fairly high (about 2200 RPM) to give it some stability. It sounds like there is too much pitch which won't allow the higher RPMs. Here are some links to set up your bird. http://www.swashplate.co.uk/ehbg-v16/ehbg_index.html or http://www.rcuniverse.com/forum/m_3480219/tm.htm or http://www.moretraction.com/helis/setup%20videos.htm One of those should help. The other possibilities are bum motor or batteries are underpowered.

I think I will have to change the ESC and if that does not work, I will burn this copter together with that LIPOs in a big massive flame and dance around the fire

Status: offline 		i'm assuming you have a brushed motor. either way 7amps at full throttle won't get it very far off the ground. thats approximately hovering amps for the DF 35. if your motor was good you would have to be at 1-2 deg. pitch to read that low amperage at full throttle or your batterys are way under capacity. it's possible your main gear or pinion gear is slipping on the shaft or the one way bearing is slipping either in the main gear or the bearing itself is not locking completely. hold the main gear from rotating and try to rotate the main shaft counter clockwise as viewed from the top. if you can rotate the mainshaft in that direction then something is slipping causing low head speed. if not, since you tried a different speed controller with the same results, the motor is probably gone. it's actually a 380 motor you can get at most lhs or online for under $10USD. Also, are you certain your batterys are fully charged before attempting to use them? your 3s lipo should read 12.55v - 12.60v with no load when fully charged.

Status: offline 		As Hueyman stated it may also be the mesh between the motor and the pinion. Try and spin the main gear counter clockwise it should spin quite easy and not be rough. If you get either of these your mesh is wrong. Give us a bit more info on what type of motor you are running and we might be able to help you out a bit more.

Status: offline 		Hello guys, I am running the stock motor, I will only be able to check these things when I get my helicopter back, at the moment I am travelling, but as you know addiction is bad and I am always thinking about my heli I got myself a new ESC and will be installing that, the gear mesh is good and there is no slippage the last time I checked, actually the head gets up to speed very well with no pitch, but when the pitch starts to increase if only for .5 of a degree the engine starts to spool down and cannot handle the added force... I have tried 3 different batteries, 2 lipos and one Nicad, so I guess the only thing left to try is the ESC, which I think might be busted since its Walkera...

Keep sending ideas, and I will test them as soon as I can...
Thanks

Status: offline 		well im just going to talk about walkerea in general i have the 22a and its perfect in every way i think most of you are complaining because they need more set up time than other "RTF" models on the market but i think we all need to remember that this is a hobby you didn't go to your local toy store and pick your helicopter up i understand that some people don't have the time to work on them thats ok find someone who does and some people just aren't mechanically inclined also ok but don't blame the equipment if you compare prices to their domestic equivilient ie' hornet,mx 400,t-rex you'll see just how much you actually save and this hobby originated with people buying "kits" you all still remember that term right ? lol so complaining that some fasteners weren't screwed all the way in is a little rediculous im not out to bash anyone i mean yes walkeras have thier issues but overall are a great value any way you cut it i also fly my humming bird elite pro 3D with a walkera reciever/speedo combo and thier 6 channel radio with no problems at all so i think everyone just need to spend a little more time seeting them up than sitting on the computer ****ing about how awful they are just my two cents

The tail rotor goes crazy, as do the gears and the motor itself, but there just doesn't seem to be "bite" somewhere between the motor and the main rotor. The gears seem to be grabbing just fine . . . where else do I look?

Try turning the main rotors backwards by hand. They should turn the main gear, motor and tail rotor. It sounds like the one-way bearing is slipping or the whole bearing is slipping in the main gear. If the bearing is slipping in the main gear, you might be able to CA the outer portion of the bearing to the main gear. Hope this helps.

When I turn the rotor backwards, everything turns. Still the bearing, do you think? I figure I'll take it apart and look at it, either way. Also - forgive my ignorance - what does "CA" mean?

Do the bearings sit directly on top of the main gear? I don't see any screws in them at all . . . I think I'll just take everything apart 'till I get down to them, and see what I find. Thanks for the quick and informative replies.
