I flew my fluttering DS811s on the ailerons of my Flip 3D for three flights. Even with sub trim in the channels to center the arm for a 90 degree start, the fluttering on the ground was embarrassingly severe with or without the engine running. Even though there was no flying problem this time, I am not going to risk my plane further with these. My gut feeling tells me it is just a matter of time. I still don't like this as once the plane lands, even as speed is still up, the fluttering starts immediately as the plane rolls out over the runnway surface.

Come on JR, I do not like your answer and will find another alternative to these servos. This is rediculous. Something is wrong with these things. Make a product update or recall. If I were on a plane that displayed these symptoms, I would get off and take another plane or alternative transportation method.

Sending them in for warranty repair at this point would be frustrating and fruitless until you step up and admit that a problem exists and you have the cure for it. I don't see that comming very soon. I'm quite certian that the engineers all thought the MD80 Jackscrew was just fine before it failed and killed a plane full of people through a "maintainance" problem. Is a spectator or pilot going to have to be struck and injured or killed by a plane with these servos gone wild before you fix or replace them with something that works? Will it take a judge's ruling that a problem exists and the liability is yours before you do something for the consumers of this poor product?

Look for mine on ebay or in my trash can if you want them.
