Leopard 5055-7T 550kv Brushless Airplane Motor
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.
