RE: Walkera Dragonfly #36
The easiest thing to do would be to take a dremel and cut the notch a little deeper on the tail boom. This would allow you to have more movement to adjust the tension. "My 36's belt to tight. How can i adjust belt tension? "

RE: Walkera Dragonfly #36
You should really watch how you set the gear mesh on a new bird. Finless Bob has some good instructions on how to correctly set the mesh. You will need to create an account to view this video but it is worth the trouble. [link=http://www.helifreak.com/about13084.html]open the one for motor install and pinion setup[/link] It is for a Trex but the concept is the same. Here is some other instructional videos he has created. Very informative. [link=http://www.helifreak.com/viewforum.php?f=95]Bob's videos[/link] [quote]ORIGINAL: Orion1024 It's possible. One thing for sure about the eccentric and warped gear is that you need to set the gear mesh looser than you normally would. I've got mine set as far out as possible, without causing any potential meshing problems. When I straightened-out the main shaft, I got it exactly straight. If yours isn't very close to perfect, that could be a problem as well. Even that .2mm could be enough to cause the vibration. [/quote]

RE: Walkera Dragonfly #36
soneebee ? I was looking at your video and that's what I call bobbing. Anyway, that to me would seem to be more of an issue with the tail belt. Have you checked to see if it is slapping or maybe slipping at that high RPM? I need to get my #36 out and see what it does at that high RPM.

Check your head dampening o-rings. If they are getting bad or pinched it will cause that also. ORIGINAL: soneebee "I am still getting this wobling thing when the heli is about to take off... I have already checked everthing from the main shaft, feathering shaft and all seem to be strait without bending.. have rolled it a couple of time on glass and it was strait.. have checked the blades and they were balanced okay.. I really cant figure out whyt this 36 has this bad rhytmic vibration when its about to lift from the ground.. hhhhmmmmmm i think I have to do something on what causing this weird vibrations.. it event gets worst ones you hover the heli the whole body shakes crazy....

RE: Walkera Dragonfly #36
[quote]ORIGINAL: nathanacura [quote]ORIGINAL: hornylove76 Ok I need 120$ worth of 36 parts and a new brushless. I just seen the deal for the 450xl and the 430lf and 25a esc. My question, Will the stock walkera tx and rx work on the t-rex 450xl's collective pitch if not will it work on the 450x's? Im not sure of the mechanics of these two the only pics that I understood was with direct servo link to swashplate. Someone plese help. [/quote] THe XL is CCPM. SO ... the dragonnfly has one servo that makes it go front/back, one that makes it go up/down, one that goes side/side. They are all separate and straight forward. The CCPM has 3 servos too ... but they are mounted differently and controlled differently. On the 36, they are mounted to the swash at 12:00, and 3:00 and up front the bottom through the shaft for pitch right? On the CCPM, them are mounted at like 4:00, 8:00, and 12:00. Hmm ... therefor, either your radio, or your receiver has to know that you have CCPM so it can mix the motion of those 3 servos in order to make the helicopter move in the direction you want. The walkera tx/rx doesn't have that feature. Long story short. We alreday discussed exactly this issue a week or so ago. End result? Man ... don't go get a nice heli like that and destroy it with the world's crappiest electronics. Even the bare bones 36 doesn't deserve to use that crappy stuff. If you have a limited budget, then upgrade your electronic in your 36 instead. that would be a better move and one that positions you for the future to upgrade to something nicer. [/quote] The Trex XL comes in a few different flavors. CDE (ECCPM) and HDE. HDE would be more compatible with the Walkera electronics. ECCPM is more difficult to setup and from what I have been reading. It really requires more of a digital transmitter to setup correctly. Not saying it couldn't be setup with the Walkera but may not be as precise.

[quote]ORIGINAL: GhostCav Ok this standard Gyro has gotta go,just spent the morning setting up & checking over my #36,havent flown it in a while as I've either been flying the 30 size or it's been too windy.So I get the heli setup lovely & get a great 10 minute hover & roam around in the backgarden then when the things about 15 foot in the air it just suddenly starts spinning around crazy.So nothing unusual from when I had the old yellow tail servo,I hit the throttle hold switch(which of course lessens the spinning by reducing the main rotor torque) on my futaba & autorotate the thing down safely to the ground.Check it & as before no tail servo movement at all,I havent had this since replacing the yellow servo with a hites hs55.Disconnect the battery & reconnect after a minute but still no joy,Ive tried the servo & it's fried![:@] So even with futaba radio gear & hitec servo's the thing still gets a problem,it's gotta be the gyro(which was set to avoid maximum servo travel) now anyway so will be chucking a CSM one on come payday. Damn shame as it was flying well sweet before the servo went. [:o] [/quote] GhostCav, Check the plastic sleeve. I've had mine slide back and bind the tail pitch lever.

Second check that your paddles are of equal length from the rotor head. Make sure your belt is not to tight. It could also be that your head speed is to low possible from to much positive pitch. If you have upgraded to a CNC head then it is possible that you have pinched an O ring also. What setup do you currently have? All stock? Some mods? Brush or Brushless motor?

RE: Walkera Dragonfly #36
[quote]ORIGINAL: opjose [quote]ORIGINAL: nathanacura Hmm ... my hitec specifically said not to cut the antenna. I agree you have to set your 3d pitches first(upper right toggle switch I think), but I disagree about the specifics. Set up your 3d to be -10 to +10. Then make sure your Normal mode pitch is 0 to +10. If you're JUST starting out with the heli ... it's best to leave neg pitch out of the picture completely. It comes down VERY fast without the negative pitch anyway and if he DOES make the mistake of shutting the throttle, it's better if it doesn't go negative. The other thing ... is make sure in normal mode that 1/2 stick is 6-7deg ... not 3deg ... or it'll never get off the ground at 1/2 stick like it's supposed to. [/quote] Yup. I use -10,0,+10 myself for 3D. The slight negative is recommended as the pitch slider can vary a bit, and you do not want to end up with a heli which refuses to come done until it runs out of power.... although this is hardly ever a REAL problem... [:D] [/quote] Agree. Most 3D pilots say that it is better to learn to fly where you are hovering around 3/4 throttle. This way when you switch to 3d, you don't get the sudden change in your pitch and throttle and have to try to compensate for this drastic change. If you aren’t going to be doing 3D then 1/2 throttle would be ok. If you decide that you want to try 3D they say that you will have to learn all over again but if you learned at 3/4 throttle the transition is much smoother.

RE: Walkera Dragonfly #36
Schwede, It's almost like the ESC isn't adjusting to your throttle end points correctly. Try moving the throttle to full throttle and then plugging in the Heli battery. It should start beeping. Move it to the throttle to the lowest position and you should hear another beep. See if it does it after that. If it does then man it could be a few things. Bad ESC, or receiver. Is the pitch moving to full when you move it that quick?
