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.

Biggest problem with these motors is that the shaft is too short to use any of the "modern" props. Can't put any lock nuts, even low profile lock nuts, when using some of the newer thick "hub" props. KingKong 5040 props fit, haven't tried the 5045bn yet.
They bearings are not the smoothest, the balance is not the best, durability is OK-ish but the price is a little high IMO.I am actually using one of these on a Flite Test Tiny Trainer airplane paired with and APC 6x4e propeller and 3 cells. Works really well and is a good match for this airplane.I bought eight. There is a bit of vibration and noise.
Performance is good. Bearing durability is bad.
