This is a very high quality and powerful motor gearbox combination. At this time I have been flying one for a year in a Euphoria for ALES competition. It will easily pull the Euphoria to cut off altitude in 20 - 21 seconds, allowing plenty of extra time to punch out upwind or cruise around looking for thermals. I am very pleased with the power for weight, efficiency and overall power of this unit. I also recommend pairing it with the CNC aluminum motor mount for durability under contest flying conditions.

A short time ago, I purchased the Leomotion 3013 for my Supra. I wanted to let you know how happy I am with the purchase. I now have my power set up with a:

14 x 9 prop
3S 1300 mah Lipo
50 Amp ESC

My 64 oz supra (I have a couple of telemetry sensors on board for my Jeti radio) climbs between 8.8 and 10 m/s (depending on how fresh the battery is). Neither the motor, battery, or ESC gets warm. With this set up, I can get 3 power on's and I'll use up less than 750mah of the battery.

Thanks again for your help and patients with me! I'm a VERY happy customer!

Best Regards, Jeff

Beautifully engineered motor. The substantial front bearing requires an unacceptably large clearance hole in the firewall if a normal fibre glass plate is used. I made up a nylon spacer on the lathe but soon changed it for the PNC Innovations motor mount. Worth every penny and gives a very secure and attractive mounting.
The claimed outputs seem a bit optimistic considering the manufacturers 45A rating. However I got 470W on the bench on a 14x10 using a good 3S which I hope will be sufficient in my ALES Optimus EL.
