UMX AS3Xtra 3D?
I just got the E-Flite AS3Xtra yesterday, an when I tried to fly it, two things happened; Even with the throws set in my transmitter to 125% (the max) the control surfaces don't move enough for decent 3D. And the AS3X over corrects it. For example, I was flying it indoors yesterday (no wind) and when I did a knife-edge (without the knife-edge assistance mode turned on) the elevator was twitching, it wasn't like a normal gyro twitch, the elevator was moving fully up and down, and I couldn't control it. Also when I fly inverted it overpowers my control input and (almost every time I fly inverted) it gives it full up elevator, crashing it nose first straight into the ground. I've already had to repair the nose several times. I've tried every mode I can do with my DX6i, and they all act the same. If anyone knows how to fix this or point me to a thread where this is discussed I'd appreciate it. I don't want to have to gut this plane because it crashed so much.

It sounds like you are in a mode different than standard as3x. There are 5 modes possible and 2 of them cause severe uncontrollable porpoising with much forward speed. See this post for testing which mode you are in:http://www.rcgroups.com/forums/showp...postcount=2204 You have to have throtle on for this test to work.
I fly mine with rates at 70% and it turns and loops within 2 plane lengths. Are your control linkages setup properly, in the hole closest to the control surface? Is there damage to the hinges so you are not getting proper control movement? Are your control surfaces damaged, cracked, so the wind is able to bend them?
125% can damage linear servos.
My experience is with the 3drankin airframe but should be very similar to stock.

Thanks guys, I have it set to standard AS3X and it fly's 3D much better. When its working properly, its a nice litter 3D'er. But from all of those crashes the airframe has taken a ton of abuse, a few more good crashes and I'll have to gut it. I may even do that now because I found a website that has airframes for $35 that are compatible with the micro electronics. Here's the link
the battery is charging, but I'll try turning down the throws to save a little stress on the servos.

3drankin air frame
Glad you got it working. The frame I am using is slightly heavier than stock and MUCH stronger. But only comes in white. I use sharpie marker to color it for un detectable weight gain.
