RE: Sig Hog Bipe......Ailerons + Engine
I fly mine with an OS 91 FS. Wouldn't want anything less. Yes definitely do both sets of ailerons and a servo on each side of the lower wing. I also added an extra 1/2" to the elevator and the rudder. Move the landing gear about 1/2" forward of the stock location to cut down on the tendancy to nose over.
