RE: U-Can-Do 3d 46?
Jack,I had the YS63 in mine inverted and it was fine.With the pump/reg on that engine you will not have flooding problems.I am installing a saito 91 in it now as at 5000ft the YS flew it great-hovers at 1/2 throttle but I wanted a little more power.The YS has a new home in the new Extreme Flight profile Edge.
