Expertly designed and precisely constructed using the most advanced CNC components, Leopard Brushless Motors adhere to the highest and strictest quality standards. Leopard Power Model Co. has over 15 years experience manufacturing high quality precision hardware, and is focused on ensuring the consistency of their products. Constructed from beautifully anodized aluminum alloy and top-quality components, Leopard motors deliver optimum performance, quality, and reliability at a price much less than many other premium motor brands on the market today.

Leopard LC-series brushless motors feature an extended shaft which protrudes out the rear of the motor. This allows the user flexible mounting options without having to disassemble the motor to reverse the shaft. The user can either (1) mount the motor in a traditional manner against the front of a firewall and use the included bolt-on prop adapter, or (2) mount it against the rear of the firewall with the shaft extending forward. This mounting option is most common in sailplanes or racer-style models and requires you to use a collet-style adapter available separately or sometimes included with your model.

What's included:

● (1) LC3542-7T 780kv motor, pre-soldered with 3.5mm male bullet connectors
● (1) Set of matching 3.5mm bullet connectors for your ESC
● (1) X-mount plate
● (1) Bolt-on style threaded prop adapter

Great Motor for the money

As always Altitudehobbies is fantastic!

This is a good motor with a nice build quality, in fact, It's the 3rd motor from leopard I have purchased. The bearings seem to be of good quality, the windings are tight and look to be clean. Mounting hardware is lightweight aluminum. I would say this is a 5 start motor, however find the "Wires" attached to the preinstalled bullet connectors are just extension's of the motor windings and rather brittle. I have had to solder new bullet plugs onto the wire's on 2 motors. This would be the best motor's money could buy if the wires where dense silicone. Otherwise money well spent.

Best motor I have ever used

This motor puts out as much power as a hacker 30 12 xl . Quiet cool and efficient. runs longer than any on the same 4s battery.
