They have the RS combos, but there is an issue with "locked" rotor detection in hybrid mode that needs to be sorted out. The tekin units are solid in sensored mode. I run a 21.5 rs combo in my XC chassis.
PS It is track day up at Dirtrunners on sat if you are interested...
Got to wait until summer vacation. I'm also swamped with quotes from my EMS clients and I've been working my butt off. I'm also testing a new ESC for another manufacturer.
