Since its launch in 1994 the ZG45SL has proved to be a veritable wolf in sheeps clothing. Its horizontally opposed inlet and exhaust, as well as allowing a very compact design, make this engine among the most powerful for its size available today.

It features a very high power magneto/electronic ignition producing a strong spark from very low revs making the engine easy to start, even when wet, with the now legendary Zenoah reliability.

Your propellers are safely secured with a large single bolt to its very wide hub flange, avoiding the need to weaken them by drilling for multi-bolt hubs.

As the power and torque curves show the compact, low vibration ZG45SL has a wide useable RPM range ideal for scale aerobatic applications where load varies throughout the manoeuvres, this engine just keeps pulling, with typical Zenoah throttlability. Its very efficient, extra thin cooling fins keep it cool as it performs. Ideal in our new 92" Maule design.

Supplied complete with mount and standard silencer.
