just be sure ur brakes are in good order, and u have a failsafe fitted!

make sure u threadlock all metal to metal screws, all gears mesh ok etc etc, just like u would with the stock motor - if u miss anything tho, the os is less forgiving...

if it does give u any trouble, first things to try are the metal brake seat, and run longer screws thru the engine mount plate so u can fit nylock nuts to them.

25% nitro, os#8 plug and a OS T1030 tuned pipe come highly recommended with that motor.

Have fun.
