So ive got a hangar 9 edge 540 1.20 and a Giant u can do 3d. So im woundering (were going to imagine money doesnt matter) so strictly on performance what does the best for hovering and high impact 3d? ive heard that a 2 stroke is the worst choose, 4 stroke is 1 step up and gas is the best. In the size category im looking at my choices are saito 1.80, os 1.60 fx and Zenoah G38. So tell me generally what kind of engine is best, 2 stroke, 4 stroke or gas? thanks guys!
