hey ferris !, thats right some masking tape to hold the props in place, i'm not sure about putting that in there without painting the spinner and the propellers...

btw, i was just looking at the turbo superchargers that come with the kit and they look kinda funny.... the intake and the body look small when you put it in its socket.... I honestly don't know how to improve that....

thanks for stopping by !

have fun  ;D
