would definitely have to do some research and see what will and will not work on my sunsation (if someone knows for sure) before I start something like this. I'm just lurking and learning, but I do know I want more hp or a totally new boat.

you realy should change out the rings and put the HD billet imco rings on it. Thats what I did. I have been told that the scx upper will bind up on the standerd gimbal ring when trimmed all the way down. The best thing to do is call imco they were great to deal with .

thanks. is there any lose or gain in hp running the scx drives???? I assume some kinda lose due to heavier built drives but that may not be the case.
