Gesh,

With all this 120 4 stroke talk is making me nervous. My wife was awsome enouph to buy me my GP GEE BEE and she bought me ALL THE SUPPORT STUFF.....Motor/servos/battery/reciever+crystal etc. (awsome isn't she????????!!!)

She bought the "SUGESTED" 2 stroke option....an O.S. Max 91 FX I have NOT found anyone flying this power setup.

Am I screwed on preformance?
Bad scale propeller?
Not good "minimal" flight cheracteristics?

Should I exchange my brand new O.S. Max 91 FX for a Saito 120 4 stroke?

I planned for a pitts style muffler for this jewel with the OS 91.......


Should I be concerned with this setup?
Please, suggestions.

Kevin
