RE: Engine for Funtana X50
I fly 3-d with my Harrier 46. I started out with the ASP 52 xls twostroke in the nose and then I tried the MVVS 49 twostroke, both of these engines would hover the plane at around half throttle and pull out nice, but then I mounted my Magnum 91 fourstroke and it would also hover around half throttle and pull out about the same. The main difference is that I have a much better "feel" of the throttle and have alot better control when using the fourstroke. It was just easier to control and maintain a hover when using 4 stroke power, plus the sound alone is worth it.
