Hi, I am new to RC's so please refrain from flaming if this has been talked about before, I searched but couldn't find anything........

I currently have two RC10GT's and both have an OS Max engine (not sure on exact engine model) and both are roto starts. I would like to convert one of them to pull start, how hard is this to do and what parts would I need to do so, can you please post up how to do this and what exact parts I would need to accomplish this...

Thank You in advance.....
