After some racing on carpet and tarmac I am starting to feel really happy with car.
I have changed the steering crank, I am using the ones for the 12th car, R12-26CL the + 1.75 mm version. It makes steering more smoother and a bit more direct as it has a lot less ackerman.
The body I am using is the Montech F13.
The One They Call Dirty, you can remove the fan on the speedo, with blinky and a 21.5T motor speed will never get anything near hot.
Cheers
Javier
