Has there been a problem with the .46 size UCD3D and aileron flutter?

A friend brought his out to the field Sunday for the maiden flight. There was about a 10-15mph wind. After he took off and headed downwind everything seemed fine but when he opened it up and turned back into the wind ,straight and level, the ailerons started flapping violently and before he could back out of the throttle the flutter had ripped both the aileron servos completely out of the wing taking most of the covering from the bottom of the wing with them. He used rudder and almost got the thing down in one piece but caught a wingtip and the resulting 1/2 cartwheel broke the fuse in half.

We had checked the plane out on the ground and there was little or no play in any of the control surfaces and very little if any gap in the hinge line. He was using Hitec 425BB servos on the ailerons and had a OS 46FX on the nose so it surely wasn't overpowered.

When I say it fluttered I men it FLUTTERED! It was about 50-75 yards out and you could see the ailerons flapping like a bird. It only took a second or two before it tore the wing up.

Just wondering if this is something that is a known problem with the .46 UCD3D or if this was an isolated case.
