Haven’t had a chance to maiden this motor yet. I installed in a newly built raw 700. Quality is very nice and seems like will be a strong motor. Only spooled up for test purposes. Running on a sequre 14200 pro esc also purchased from Heli direct and am very happy with decision so far. Running on a frsky rf007 tandem flight controller with a tandem x20s radiio and couldn’t be happier with everything. The Heli hobby has sure come a long, long way. Looking forward to some better weather to get this Heli in the air. As always Heli direct rocks and have always had a good expierience with them.

It arrived without any issues, but why is "1.5mm" stamped on the motor itself?

This Combove motor looks & feels genuinely like great quality. With 520kv and power output up to 12,800 watts, it’s a torque monster and a powerhouse of a motor. This motor should be able to swing large blades of most sizes for any 700 class heli. I got it for my GooSky RS7 Legend to see how the motor performs. For the price, you will be hard pressed to find something with this kind of power and performance.
