12mm x 30 x 4000kv Afterburner Motors

The best 12mm Inrunner ever made. 1.5mm or 2mm shaft. This motor is amazing on 2 or 3 cells and a 3-2, 3-3 or 4x2.5 GWS props. I've always found the 4000kv version of this motor to be more useful across a wider range of props and battery packs. To my knowledge there has never been a finer 12mm motor made than this brand. Now that the shafts are updated to 2mm, they are perfect! Using in a gearbox will require you to drill the gear to press fit on the shaft or obtain a set screw style gear with 2mm bore and the same modulus as the IPD drive (if you use one of those). The vast majority of users apply this motor direct drive.

Choose your shaft size below. 1.5mm for IPS gearbox use, some ducted fans and pusher use. We recommend the stronger 2mm shaft for direct drive tractor use.
