Upper ailerons on Kyosho Super Stearman
FYI
Robin, Bab's wicked stepsister, has piloted her Super Stearman for five years now. She gets one roll each 1 1/2 seconds at full throttle using a TT .46 and Bisson behind a MA 11 x 6 prop. Don't know precisely if it's because the hinge lines are sealed.
Are yours?
