anyone flying / flown the 4*60 on a lower displacement 4-stroke? Im wondering how it flies on a .72 4s or a .60 2s. Im building one now and I have a Saito .72 available to use. Problem is that's on the LOW end of the recommended engine range. I hear about people taking off at 1/2 throttle and hovering it with their .90s and .100s.
Now, I KNOW a 72 4s is not ideal! =) But I don't want to do vertical maneuvers, just enough engine to do some lazy aerobatics and not be (unsafely) marginal on power. I do build very light, so it won't be a clunker. Yes, I know I could pick up a 2s .70 for under $100, or a Magnum 4-s for under $200, but really I just don't have the $$$ right now. =)
