OK, folks.

Here's one to ponder.

My (kit built) Electrostreak had its first crash when it lost an aileron a few weeks ago.

It had tape hinges, after some five years of service one hinge let go.

In the crash it bent the motor armature, so in repairing it I installed a CEM 0506 cobalt motor, and used monocote to replace the hinges. Standard skin method, fully sealed upper and lower.

It turned out a LOT faster than it was with the 550 can motor, flat out level flight - flutter.

I took the easy way out - put a 550 can back in it. More than sufficient power.

Point is, if there is a flutter that is highly resistant to a cure, just slow down.

That wont work for rsieminski, of course, since his object is to go faster. But for the rest of us...

Ailerons always roar?
. Cut the throttle a bit more.

Bill.
