This is an awesome direct drive Motor. A good up grade for GWS war birds and/or park flyers in the speed 400 range. Did we mention one of the best flat foam 3D motors for the buck?
This motor is comparable to the, Aurora 400XT, Essky 400XT, and the Motor Max (MTM) 400XT. But un-like the other brands the shaft is easily reversible and/or replaceable.
Motor comes with 3.0mm shaft, an X mount, and screws. Does not come with bullet type connectors to plug to the ESC. Fits in to any GWS type speed 400 gear box. And has fit every aluminum outrunner type mount I have tried so far. Mounting holes are 16mm (or roughly 5/8 in.)
Aside form the awesome performance of this line of motors. They are extremely user friendly.
The shaft can be moved from pusher to puller. Simply loosen an allen screw and the shaft slides out. Flip it over, tighten it back up and you have a pusher motor. Un-like others on the market, to change the shaft you do not need a press and the bell does not need heated possibly causing damage to the magnets. So you can swap from pusher jet or wing to your favorite puller application with ease.
Recently reworked the shaft now has very close tolerances eliminating vibration, Magnets are good to 180 degrees, High speed bearings supporting the shaft on both ends. And very rare in the industry the stator is double bonded limiting stator movement on nose in landings/crashes. All leading to better efficiency and increased power.
All shafts are 3.0 mm. Should you break a shaft we do carry them or, any GWS, MPI, or any other 3.0mm shaft will fit. We suggest using a prop saver it will help reduce prop breakage and shaft bends on the not so perfect landings.
