First off it is a 4 pole motor and requires a controller that can handle a 4 pole motor, second it is fairly hard on the controller because the shaft takes alot to move by hand (a regular BL motor is super easy), and third, for the price, I think there pretty expensive and highly overrated. Serum had one (a BigMaxximum actually) and he sold it and used a Feigao XL instead I believe.
