Its a badd ass reliable motor. Just not a great speed run motor. At least not in my experience...88mph was the fastest I could pull with it, with the spectrum 160a esc. No worries. Itll go in my xmaxx or kraton exb. Just for bashing.!!!

Great product, works perfectly to as intended. So far I’ve only been testing it and seeing what build I should put it in. Right now I’m thinking of a limitless build. Overall very smooth and high quality motor.
