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.
The Airplane version of Leopard brushless motors features a long shaft which extends past the rear of the motor, allowing the user to either use the included bolt-on prop adapter for traditional mounting, or reverse the shaft for front-mounting applications.
Each motor includes pre-installed male 4.0mm bullet connectors and an accessory pack with a matching set of female bullet connectors for your ESC, an X-mount plate, and a bolt-on style threaded prop adapter.
