Got a Jammin SCRT10 back in December and I have been running it almost every weekend. Great truck, had a CRT.5 before which was my favorite truck and I must say the SCRT10 handles so much better (longer chassis). The only thing I wasn't thrilled about were the smaller wheels/tires. They work ok, but your pretty much with Jammin unless you convert to Slash size wheels (which I have done). Currently running a Novak hv 4.5 and MMP on 2s. Running the Novak because it is a larger sized motor (runs cooler) but it has a high kv so it will run on 2s lipo.

Stock body and Jammin wheels/tires.

Slash wheels and modded front bumper.

Now running Slash sized wheels and an Associated SC10 body. That's my Slash PE 4x4 in the background.
