I never did flush the pump. That may be the problem.

I had lost interest in flying this plane until this year so it just sat in the basement ignored. I had forgotten what a thrill it was to fly.

I just had rotator cuff surgery so I won't be flying for a while and want to give this plane an overhaul. New servos, retracts and a reliable Hanno Spec.

Anyone know of someone that works on these engines?
