Just installed this motor in my FMS 70MM YAK with a custom fan and heatsink. Lots of power, seems great quality so far after a few flights. Time will tell. Motor is pretty heavy over all, but the price was right. Great budget motor..

Nice motor....6s 5-5 speed prop 80 amp speed controller in a Roc hobby swift no info on speed but guessing around 140 mph.... Again very impressive motor! A little warm but nothing extreme.

I'm so impressed by the built quality of this motor. very well put together.. the wires are good. it has a notch on the front side of the shaft for better grip of the grub screw on the adapter. also the shaft extends to the back for a reason. did you ever try to tighten up the rotor nut but the motor was spinning? that's the reason of the shaft extension in the back which is not rounded to help you get a good grab with a nose pliers or any pliers so that you will tighten up the rotor nut without the motor spinning. amazing motor and performance also. with a 10 blader DPS series Impeller and a 3300mah Zippy compact 40c 6s pack I was pulling 70amps and around 1590watts IN THE PLANE (FW YAK-130 70mm)

Beast of a motor that you won't find anywhere else cheaper. Been running on a 12b FW impeller drawing over 2000wp on start up(settling to about 1700watts)in my Rebel on 6s for 3 months without a problem. This thing rocks, no better way to put it!! Keep up the awesomeness HK!

I run a pair of these in 70mm 10 blade EDF's in alloy housings on 6s. Batteries are 2700mah 6s Turnigy NanoTec 65-135C. Toasted the batteries on 10 flights. 100A Turnigy dLux controllers. 80-ish amps. Motors are fine. I believe the alloy housing helps. Cooling at 1700 watts is essential, so with that said, they'll last, so long as you keep them from overheating.

My EDF's are out of balance from sand getting into the rotors and the units ran that way for a flight or two with no bent shaft. (Since that I have re-balanced the rotors).

I will also try the 29mm by 70mm 2600kv Dr. Mad Thrust motor.

They're a good build.

Appears to be well made. Very strong magnet and nice bearings.

Fitted to multiplex funjet with a graupner cam speed 6x6 prop. 5s 2000mah 40c battery. Only done 2 flights but has reached 261km/h measured with hitec gps telemetry. Motor barely even warm.

Bench tested at over 1300watts @ 82A. Unfortunately unable to check wattage in flight. Will try 5x5 prop and 6s battery next.

Klasse Motor mit mchtig Power. Leistet mit einem APC 4,75X5,5 Propeller 1535Watt bei 71Ah Stromaufnahme an einem 3300er 6S Lipo. Mit einem anderen Propeller geht noch mehr. Der Wellendurchmesser ist 4mm und nicht 3,175mm.
