Psychic?
Ok, I put the wings on and it cut the vibration down 80% - thanks for the tip ...Always glad to learn something to make things work better and/or easier
Psychic? No.
I saw a guy start a 50cc gasser without the wings on a plane once. One of the guys in the pits told him not to start the engine without the wings on--but he wouldn't listen. About 1 minute into running the engine--horizontal stab snapped right off.
Glad I could help.
