The motors are not Roar approved. Why ?I have no idea.

The speed controllers are legal except for in stock classes where boost / timing are not allowed.
They do offer a stock esc now without boost / timing features.

Not sure about ifmar rules.

Speed runs ? Here is a video on 3s using the 5.5t motor hitting 50mph. Im sure with the 3.5t and some aggresive gearing 50mph can be done.
