Heat is the enemy, especially when it comes to electric motors. Keep your temperatures in check and your motor running efficient and cool with our Motor Heatsink with Twin Cooling Fan. The motor heatsink clips right onto your 540 or 550-sized motor, and features an anodized coating and multiple heatsink fins for added cooling surface area. The cooling fan is powered through a standard 2-pin Rx plug.
All heatsink cooling fans, unless specified otherwise, are designed to be powered by DC voltage only between 5.0V and no more than 6.0V MAXIMUM! If you choose to power our cooling fans with voltage exceeding 6.0V you are doing so at your own risk! Please make sure that your power source (battery pack, receiver, etc.) is able to supply consistent voltage no lower than 5.0V and no higher than 6.0V. If powering from an ESC, check with the ESC manufacturer to make sure if your ESC is capable of providing enough auxiliary power to handle the added load of extra cooling fans; some ESCs that have built-in fans may not be able to reliably power any additional cooling fans.
