RE: Gas Engine?
no ,that was the the 2 stroke OS 160 single on nitro.the Saito 150 or OS 160 Twin 4 stroke do not have comparable power at all,nowhere near really.Please do not compare horsepower figures on 4 sytroke and 2 stroke and gas motors.Its like comparing an electric car to a Diesel and gas engine.Each make very different power at different curves and torque.
I think Zippi put a 26 cc gasser on it,give him an email on what to expect.He has some experience with trying the smaller gassers in 1/4 scale frames.
Somebody else was going to fly it with a ZDZ40,not sure how that ever turned out..probably not much fun to fly around I'd guess.
