Any1 here have an luck with a 2 speed on a RC10GT? Is it possible? I have seen pics on other sites with it on there but no response on it working or just being a waste of time

I think the main drawback is to incorporate a 2 speed, you would most likely have to eliminate the slipper clutch.
Which might not be so bad if it were strictly on-road.

Would be nice if there was one.

I found this

There is another on rc10.com, it uses a NTC3 tranny and the engine is mounted reverse, like in a NTC3.

I already have the engine needed and the chassis so where do i sign up?
