This German 2 stroke boxer engine is manufactured by Hirth. For very many years an extremely robust and reliable engine. Thus, the "heavy" boys with girls can fly double-seated in the under 115 kg class "Medical Free".
The engine has 2 WB 37 carburetors.
The digital PVL ignition allows the engine to start very quickly and guarantees a smooth engine running, even at low speeds. Since the boxer also ignites at the same time, a perfect mass balance with very less vibration. Amazingly smooth running!
As the engine is built so compact, we additionally install large cooling heads. They safely absorb the heat from the engine and quickly discharge it to the air.
The two side "Airgrabbers" lead additional air directly to the cylinders and reduces the CHT (Cylinder Head temperatur).

We recommend on the X-LIGHT new X-WING EVO 28 RS
Based on the new X-WING EVO 28, we have now developed the RS. The glider is the same as on the XCitor, but the chute is now equipped with "normal" risers". This makes it possible to hang the glider on every trike with standard carabiners.
The special thing about the wing is its high MTOW of 437 kg.
