so, do u just check the CofG of the plane without wings????? do u do it yourself??? I could imagine you stand up over the plane and put your fingers below?????

For the servos, well, I hope it will be fine, I just have standard servos, if I see it gives me trouble, they Ill have no choice than getting high torque servos, but for ailerons it should be fine, I'll see....

P.S. Thanks for the tip of the travel of ailerons.... I'll reduce it to 80%, I want to trim it first, then I can land and increase the travel if the roll is way too slow..
