Leomotion L3013-4550

Beautifully made motor and gearbox and performs superbly in my new F5J Osprey. Running on 3s it effortlessly pulls the model up to 200m in well under 30 secs. Fitted to the Osprey with ali motor mount.

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.
