Tekin Redline brushless motor

[Mister-T]

The fact that nobody is willing to give any certification or recommendation about compatibility. Ask tekin or GM, but the answer will probably a mix maketing BS + a hidden "we don't know we've never try".
So if your not ready to take some risk then just buy a GM motor to go with your Genius 95

Edit (just my point of view)
the answer is simple Tekin motor in term of design and feeling react alot like castle motor, so it's safe for me that you can go up to 3S on most low and middle kv motor. A high KV motor will suck a lot of current specialy if you put a large gearing on this one with lot of load. It might be problem in term of acceleration if your battery can't follow (matched Nimh or 20C + lipo is a must have here)
