The other day I dusted off the EVO 10cc Ultra Stick and fixed a few gripes. Today I finished and she is flight ready.
Last year the Ugly Stick died a fantastic death when the un-commanded aileron flutter caught up with me a year ago last June. I put the same electronics into the Ultra Stick, and the flutter was still there. So I exchanged the servos in the ailerons, and put a capacitor on the receiver to clean up and stabilize the power (see that last link). Today I finally put the wing back on and in the process of tuning the engine, noted the flutter is gone. G-O-N-E, gone.
Finally, a nice idle that is a little unstable, but not quitting,
very nice high end RPM output, and no aileron flutter!
I love this plane. I hope her performance doesn't disappoint.
Evolution 10cc. Not a big fan of the carb.
Weighs in at 9-1/2 lbs, consistent with the weight last fall. She is "designed" for 7 lbs, I wonder if that's her electric weight? Her dry CG is spot on.
But it took a pound of lead (473gms) as one momma block under that white piece of foam, up against the forward bulkhead. It took almost as much if I used smaller weights packed in more forward, around the fuel tank. Opted to just keep the honker in place.
Tomorrow, weather permitting, we fly!
