Hi, has anyone tried the new O.S. FSa-110 with this ARF? I do have a very trustworthy O.S. FS91 with pump, but since I intend to add smoke and both engines share more or less the same dimensions AND weight, yet the FSa-110 is more powerful, wouldn't it be better? Is there something that I do not take into account (for example, better go with the pumped engine). I must add that I would also like to use 2 servos for the elevators, add smoke and still be able to have unlimited vertical. Any thoughts?
