Well I certainly have taken a lot of criticsm here thank you guys. I did an air test with a 30 cm wingspan free flight glider with a ridge on the right wings which is about 5-6 times thicker than the airfoil max thickness-2 mm. The glider did not show much response to the ridge "spoiler" except that when at low speed the glider banked on the right side. I figure that the ridge on my plane will not have a big effect but I will get rid of it in september before the maiden. How is my decision to yall?
