Absolute Junk
 
I took a chance and purchased a Dragonfly 35, and let me tell you, what a waste of money. First of all, no adjusting or tweaking ever got it into the air, just light on the skids. Second, none of the electronics seem to work as advertised, I don't even know where to begin listing the problems I've had. Third, the English instructions aren’t even worth the paper they're printed on. I think I would've been better off with the Chinese instructions and translating them myself.

If anyone knows what can be done with this turd, I welcome any advice.

None of the electrics that have a second motor for the tail rotor fly worth a hoot. All of the rest fly but cost as much as a decent .30 size fuel helo, so get a .30 ....

You get what you pay for. Say that over and over before you buy your next one.

I think I've traced the electrical problems down to the receiver. When I plug the Heli's battery in and turn the transmitter on, the gyro doesn't initialize, the roll servo tries to go past full right, and the motor sometime starts by itself for not reason. Could this all be caused by a bad receiver?

I'd like to add that when the motor starts by itself, it goes to full trottle.

LOL....yep, I agree with barracudahockey. shelve it, buy a raptor, caliber or a venture and learn to fly on a nitro machine. Then next summer go back and tinker with the Dragonfly if by then you still think its worth playing with. You might not like or agree with this idea but its probably the best way to go.

Have you verified that your TX and RX are on the same frequency? TX and RX on same signal format (PPM or PCM)?


Good Luck,

All of the controls were responding and operating as advertised until it had a run-in with a chair. Both the TX and RX say 72 MHZ. Before the chair incident, the skids were actually off the ground, so I think it wants to fly.

Hate to read things like this. We keep saying don't buy the cheap junk helis and people keep doing it. Not fun. Hope you will get a good one and an instructor and learn. its a fun hobby when done right.

I found the problem with the funky servo. I disassembled it and found a broken wire. The wire is for the limit switch and with it broken, the servo wants act like a motor and just spin. The throttle was just some dumb a__ (i.e. me) bumping the throttle lever. Does anyone know where I can buy just one servo? Everywhere I've looked online sells only sets of four. I'm going to patch it together and try not to crash it again.

You should always turn your transmitter on before you plug the battery in on the heli and always unplug the battery from the heli before you turn the transmitter off.

72Mhz is the band ... it is not a specific frequency (channel). Your frequency is 72.xxx. It is important that the xxx are the same on the TX & RX.

Good Luck,

allerc.com sells their 9 gram servos for $12 last time i purchased. fast shiping too. or you can go to your LHS and get replacement servos (hitec h56 is popular for micros) for around $18 each.
