I am introducing a POWERFUL outrunner, the Xmotor 400B. This smooth running outrunner has a Kv rating of 950 and a max efficiency of 79%. The 12 poles help create MASSIVE TORQUE on a 3.27 mm shaft and weighing only 55 grams. The shaft can be replaced by removing a simple lock nut!

I flight tested this motor to determine actual thrust on different propellers. On 2 cells a GWS 1260 will yield 20 oz, and 3 cells yields 26 oz of thrust! This motor will handle planes from 10-20 oz! This motor is similar to a Hacker A20-20L that retails for $70!

This powerful motor also include:
Firewall Mount
3D Wobble Prop Saver
2 O Rings
Hardend Steel Prop Adapter
3.5 mm Female plugs for ESC
Mounting ScrewsThis motor is an exceptional value and quality! I offer full support for the motors including extra firewall mounts, shafts, and prop adapters!

This motor comes in a smaller size also, the 300B, 1220 kv!

I sure can!
These results were all done using GWS props, TowerPro ESC and a 1350 8C Dualsky battery. The power might be a little better with APC props and a Higher C rating battery! To obtain this data we mounted the motor on a device similar to this:
