I can't recommend these motors for use on a quadcopter. They are extremely fragile. I've broken 4 of them so far, and all 4 have broken in the exact same spot. They perform well and if you don't EVER crash you may be fine, but I've had bad luck with them.

These have good torque for 4 in props but can get hot using 4s on even 3 inch propellers. Shaft broke quickly.

Made qualitatively. Weak the shaft and it breaks from a small fall. It is necessary to install soft propellers. Separately, parts are not for sale! I had to buy a new motor. Not a reliable product.

Two shafts broken under a very short period of time. DYS needs to make these a lot more durable.
