RE: showtime
That's far more power than you would ever need in that model. You will most likely need to add some tailweight if you go this way. The more weight you put out at the ends of the fuselage, the more you emulate a flying barbell. Snaps and spins won't stop as well. It adds to your workload to do smooth rudder integration in rolls. A 120AX is about as much as you would ever need in this. It balances out well with that engine.
