I have a Sig fazer, it weighs a little less the yours and I am running a os46fx with a 12x4 apc prop. The cg is set a seven inches from the trailing edge at the wing root. (against the fuselage) which makes it fairly tail heavy. I would reccomed using a 46 or maybe a 50 depending on the weight of the motor you choose. You want to keep it light!!!! As a 3d plane the fazer does not excel, it does not harrier or do elevators due to really bad wing rock. However it does hover easily and spins quite well too. Add flaperons for really tight loops and waterfalls!!! Good fun to fly
