Which engine would be the better choice? Both can made to balance the plane by moving the engine. I had a Twister powered by a HP .40 and it was a dream to fly. I do not know if I would be satisfied with as OS .35 Stunt engine. Thoughts / Suggestions? Tia
My Twister has an OS LA .40 in it, and it flies amazing.
HP 40.And try to obtain it with original, genuine venturi, with original one-side nozzle type needle assy. (I think MECOA offers it).
