I hate sensor wires! I like neat and tidy wiring, and try to stay away from Novak's if possible due to their none replaceable harness. It mkaes no sense to have a 9" wire if your motor and ESC are on the same side, 1/2" apart! But Havent had harness issues either. It seems lately I've started running castle products in offroad with various motors, including a Tekin 358. Being able to run both sensored, and sensorless is priceless!
