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.

These little motors rock! I bought them for a 330 size home-build mini-quad and they are perfect. I get 7-8 minutes of flight time with APC 7X5 props with a 2200 mah 3S lipo (50C), and about 5 minutes of flight time with a 1500 mah 3S (40C). I'm sure the quad would scream on 4S with 6-inch props but I haven't gone there yet, since I don't need the speed. The little quad weighs about 840 grams with 2200 lipo and GoPro.
The one complaint I have is that the prop mounts are rather soft and I have bent two so far. Hopefully, I can find the replacement parts, fortunately they are replaceable.
