How do sealed hingelines stop flutter ?
The only thing they can do in this respect, is to act as a braking device-that is - stop the free movement of the surfaces
If the rest of the setup is loosy -then this damping "may" help.
I fly my 50cc EFYAK wide open-it has huge ailerons and the engine turns 8340 in level flight on Mejzlic 22x8- (on board tattle tale tach records rpm )so it is movin - no sealed ailerons or elevators
Good linkages and JR8411 servos hold well
I am assembling the Showtime this week -using a Saito 100 and a big dose of nitro-
Looking forward to it --
