Thanks to the strong demand of the RENNTECH /AIXRO XR50 and its popularity among the aviation community, we present the XF40 rotary aviation engine. Built with the aviation enthusiast in mind, the XF40 combines the effeciency of the XR50 karting motor with many engineering enhancements to get your project airborne.

What makes the RENNTECH /AIXRO XF40 aviation-ready?

Bearings: More robust/ temperature-resistant cages.
Water Pump: Water pump driven by a tooth belt is attached to the engine. It can be mounted in two different positions, so the outlet can always point upwards (important to avoid air in the pump).
Housing Vents: The trochoid housing as well as the two side plates are equipped with connectors for 6mm tubes, allowing air to escape from the water channels when mounted “feet up”.
V-Belt Pulley: The pulley is now auto-ventilated and attached to the balance weight.
Ignition: Two different ignitions are available, both now located on the clutch-side. The first is a magneto type system, but with a CDI to vary ignition timing and a start supply. The second is a battery system as used in automotive applications.
Carburetor: Bing carb with K&N air filter.
Intake: Mechanical device, mounted inline with the throttle cable, opens the direct intake on the last quarter of the carburetor opening.
