All this talk of Stearmans has prompted me to chime in about my N2S-1. It's the Kyosho PT-17 but the fuse recovered to resemble the Navy trainer. Identical to the Kysho Stearman except for the covering and radial engine. It flies great on an OS52 with an 11x7 prop. I tried the 12x6 but performance suffered. I have no problem with just the lower ailerons. Roll rate is very good. It must be phenomenal with ailerons on the upper wing. I have more details on my website about the plane.
