RE: Great Planes Reactor ARF .46-.70 - Build Thread
Hey guys, what prop would you suggest for an OS 70 four stroke? I intend to use this engine on mine and have not had a chance to fly it yet due to weather. The OS 70 can fly with a 12 x 8, 13 x 6 or 13 x 8 --- any suggestions or notes of experience with this engine?
Thanks, TKNA
