It's the most common problem with A direct drive car.
I've also used to drive with A fully hop-uped F103rs everywhere I could.
But it was so frustrated that I didn't had any grip.
The first time I went to A track was A blast!
So much difference, and I from that moment I was hooked up on this hobby!
I still have that car, don't drive it anymore, but I am planning to start racing with it again, it's just so much fun!
