Are you going to race it or bash it? I love RPM stuff. It's strong and flexible. I've never broken anything RPM before.

From what I remember about my GT, the idler gear in the tranny is pretty weak. If I was you, I would run it until I stripped it though. But then replace it with a Robinson Racing hardened idler gear. Locktite everything!!! Since I was mostly a basher, I got the RPM reciever box to protect the reciever from the weather. If you get a kit without an engine, definately get the OS .12 CVR for it.
