My experience with the Ultima SC

[gtxracer]

Little update...

I currently have a Mamba Pro/7.5R in there with Neu lipos. I also bought the Velvet shocks, upgraded motor plate, and the Kyosho CVDs. It's a lot smoother now but still got some cogging with the MP/7.5R setup. I am going to order a RS/10.5 combo soon I think, Tekin has always been good to me.

Also, use some rubber compound on the stock tires and it really makes them stick. Don't even need calibers after a couple sessions with the compound.
