UF1 RC 
In an effort to keep things a little spicy in the Formula 1 class, drivers will be allowed to run either a 21.5T or 25.5T motor at each racing venue!
Small or loose tracks; maybe you’ll want to run a 25.5T for more control or less wheelspin. Larger tracks – maybe drop in a 21.5T for that extra horsepower on the straights.
It’s certainly going to make things interesting – who can choose the right power-plant for track conditions!
Legal 21.5T/25.5T F1 motors MUST be ROAR approved. They can be fixed timing or adjustable with whatever gearing you’d like.
This is for the F1 class only – F2 drivers will still need to run any ROAR-approved 25.5T motor.
Let the racing begin!
