Your engine is more than enough for that airplane provided you prop it right and use 5-10% nitro fuel.
Best props are Graupner G Sonic, RAM or APC. Stay away from white tipped Master A props! 13x8 or 14x6 is what I would use. And most important ...build the plane light! Remove as much wood you can and use the lightest possible wheels and use a 240-300cc tank. Not more!
