Quanum MT series motors are Spec built by DYS, well known in the industry for their quality and performance.
The MT line uses quality NMB bearings, high pole counts for torque and smooth operation and all have standardized universal mountings in their given size. Quanum has spec’d the motors with N42sh magnets and .2mm laminations for optimal efficiency. The MT’s also have ample motor wire length for a cut to fit installation, with included bullet connectors and shrink tube. Another great feature is that Quanum spec’d all the motors to come with mounting hardware in various lengths, as well as both hub and direct mount propeller options, so installation is a snap.
Each Quanum motor is QC checked for balance, wind, performance and mechanical tolerance. The DYS brand is well known for their BE series and the new spec built MT line will set new standards of value vs performance.

I run these motors on a 720 quadcopter with 17" CF props. With a 6S 10C 6000mAh pack, I am able to get 30 minutes of real flight time. These motors are quiet and perform great. They are generally not even warm after a flight. Highly recommended for the price!I ordered 7 of this motors half year ago. They are really nice motors. They some small isuses with screws etc, but overal quality is nice. They have big bearings, they are super efficient and really cheap. I will reccomend those motors to anyone.Poor quality motors. I ordered 6 of them and I found that each motor has some or the other built issues. I will post a video of this motor and you will be then quite clear about it.
Major con: 90pcnt of the screws go dead on tightening. They do not provide sufficient grip.
I wouldn't recommend buying these. Quanum, don't market with false quality promises. We put our money in these for good quality.
