Hello GRVW
Heres a link of a display flight at an air show I did recently with my P80 powered Viper. Plenty of power for everything right from takeoff as you'll see. I did build it super light though, only because I already had a P80. Only one fuel tank, no cockpit or ballast.
Starting from scratch though as others have said a 120 would be good also. Don't worry about stall/landing speed. It's a floater.
