I just bought a Top Cap from a friend and would like some suggestions on an engine from people who have actually owned them.It was flying with an OS 46FX and did fine,but would hover at almost full throttle,with no pull out power.I want an engine that will give me Pull out authority without compromising weight.I want to be reasonable,not like a Saito 100 or something rediculous like that.I am thinking of an OS or Saito 70-724-stroke Maybe an OS 50 2-stroke.I am not sure how much more power it has than the 46.BTW,we tried all the pouplar props on the 46 and it just didn't get it.Thanks,
Mike
