Hi, i agree on the sealing gaps up

but ... that model flies at my site with a reccommended os 91fx .. it will fly imac full 3d and every thing in the book using the throttle any where from idle to full ... The engine size in the model was the problem because of the size of the control surfaces on it... if the model were the likes of a mustang or even somthing like a 90 size extra.. the story would be different because the controll surfaces wouldn't be prone to flutter at such high speeds (created by the larger engine thrust) unlike those on a funfly .....


Just my chips
