RE: Balsa USA 1/4 Scale Cub build threads?
My 1/4 scale scratch built L-4 is powered by the Evolution G26. I feel it flies the plane well, after all a Cub is not a 3D plane. I also have a Sig Cub with a G38 and it has too much power. and last I have the hanger 9 Cub with a Zenoa G26 in it and it has plenty of power for that plane.
