This is the one to get for your 250 copter. Cannot beat value/performance.Punchy little motor- fits a 250 perfectly, looks a lot like the align version. Soldering esc connectors onto the bullets is fiddly, they're tiny.Good motor. To use with the HK250GT kit you'll need to pick up a different pinion. This motor has a 2.3mm shaft, while the pinion that comes with the kit is 2.5mm.Nice motor. The bullet connectors aren't the same bullets that most ESC's use. They are quite a bit smaller so you will have to resolder the leads. I prefer larger bullets. The motor shaft is also completely round, so you will have to use a file and make a flat spot for the pinion gear scrub screw to mount against.Outstanding little 250 motor. 3s/15t pinion, it's still working great after about 25 flights, 4 crashes. It came with the text "Assault 3600 250" on it instead of Turnigy. This motor comes with no flat side for a pinion on the output shaft so you have to grind a flat side yourself & use red loctite when applying the pinion.250 iin ideal oldugunu okudum aldim. deneyecez bakalim.I've used this motor for my HK-250 helicopter.
It fits perfectly,distance between mounting holes is compatible with HK-250 motor mount.
Shaft size is also perfect for HK-250, so no cutting is needed. Shaft diameter is 2.3mm.
With Turnigy 3S 800mA/h flight time is slightly above 10 minutes (simple flying, since I'm not flying 3D yet). Temperature is below 50C.
So it's pretty good motor for an excellent price.
