Ran, into my first major issue. The CEN TR uses 26T/9T front/rear diff gearing (2.888888) which is pretty high. The nitro CEN uses a 52T spur to make up for the high diff gearing but I am using a 46T plastic spur. Even with an 11T pinion I get a top speed of around 50mph, too high for what I need (track). I was going to pop in some spare Kyosho diffs I have, but I remembered that the CEN TR has really long outdrives and the Kyosho has shorter ones, using the Kyosho outdrives will cause the dogbones to pop out. So I guess I will try and mate the Kyosho ring gear and pinion to the CEN diff.
