RE: Model Tech Extra 300 ARF with a 40 FX?
I've got this plane with a GMS .32 on it and running an 11-6 it pulls unlimited vertical very well. Put taller wheels on for grass a the long prop and it lands vey wall. Slows down to a very managable speed. Not hot landing at all. A real blast to fly - really should pick one up for a spare.
