This thread is causing me to think that it might be wise to go back to using TSR motors in my Hardbody cars on the Flat track. I drive best on that track with good strong brakes. I know I've had more than a few occasions when I've done much worse due to fading brakes in Retro Hawks on that track (Pablo has heard me complain a lot about this with the Lola he sent me to race). But that will take new side/anglewinder chassis, not just swapping a motor and gear, like for inline cars.
