I've been flying me nice new Modeltech Formula 3D over the weekend, flies great but am having to be REAL careful with the throttle to avoid flutter on the elevators, I can barely get up to knife-edge speed without it happening. I'm using the supplied hardware, and there doesn't appear to be too much play in the setup, tho I must admit I am only using standard servos at present.

Another more adept flier who flies a Hype had a go and commented on the same thing, so I'm happy it's not a case of just flying it too darn fast which we know it's not designed for. He also took a look at the linkages and didn't think the play was much different than on his hype which is also using standard servos.

Suggestions?
