Hey guys the images will make clearer what im about to say but here it goes
I recently purchased a Hobao Hyper 9 from an ebay seller ,all as well and everything worked apart from the pullstart which expanded,so i have to replace that but i want to replace it with a Rotostart,from looking at my engine i dont think i can do this but maybe you guys can tell me what i need to do to make this possible
Heres the images anyway, the engine is a .21 nitro
