They are banning products not designed around sensored motor systems (basically the style that the owner companies make). Also, there can be no variable timing. That throws sensorless out the window since by design it has to have variable timing to keep in synch. Sure the mamba max is too much power for most race tracks, but smaller sensorless motors could be used.
We should get together and make our own organisation. Allow real power houses to compete and kick the weak sensored crap out. Don't forget about Trinity. Yes I own a few brushless motors from them, but I haven't forgot the adds they had in the magazines. Now they have lipo and gues what, I'm sure lipos will be ROAR legal too. People should stop attending ROAR events just because they don't want new technology going there.
