Mega motors are produced using the highest grade magnets and wire by a small team of engineers in Brno, Czech Republic. An Asian distributor owns 10 Mega motors for use in his own personal models!
Mega 16/15/6 used for testing purposes only, in very good condition - no box.
The Mega 22/45/1E is mainly used in larger fast electric boats with 4S and 5S batteries, and is also suitable for EDF with 90mm fans using 6S and 7S LiPo (current limit is 100A). This motor can be used exactly the same as the Mega 22/30/2, but the slightly extra weight and length results in a higher torque motor with current capability up to 100A.
Mega 16/25/2 is a conventional 6 pole brushless motor designed for direct drive use in fast aerobatic models. Can also be used with the Megagear gearboxes in thermal soarers. Typical use is with 5,5x4,3 propellers with 3S LiPoly battery packs at around 35A. Manufacturer's page for 16/25/xx
Mega 22/20/3 is a 36mm diameter 500 size motor with a 5mm shaft, suitable in boats with 3's lipo, for EDF models in 90mm fans on 4 or 5's Lipo. Thermal soarers and sports models, use 2S LiPo, and pylon racers on 3's LiPo use 7 and 8" propellers. This motor has been used for testing purposes only, and has no box.
The Mega 22/30/4E is a 36mm diameter 600 size motor with a 5mm shaft intended for use with 4S LiPo battery packs as a direct replacement for .40 4 stroke engines in vintage models flying at up to 3.5kg. The prototype of this motor is now with DB Sport and Scale in "our" Moth 40, tuning a 12x8 propeller at 35A.
