UL Power Aero Engines

ULPower Engines have been developed specifically for use in light aircraft and are manufactured to the highest standards with fully electronic ignition and multi-point fuel injection (FADEC) system as standard equipment.

ULPower Engines feature dual electronic ignition (with variable timing), excellent power-to-weight ratio, and high fuel efficiency in a conventional configuration: Air-cooled, direct drive, horizontally opposed 4-cylinder.

All ULPower engines fly on avgas and mogas — even with mixtures up to 15% ethanol — and can be upgraded with back-up and safety systems.

Sonex Aircraft provides UL Power 260 and 350-series engine mount options for the new Sonex-B, Waiex-B, and Xenos-B models, and B-Model cowlings have been designed to accomodate UL Power 4-cylinder engines using UL Power's 110mm prop hub.

UL Power North America has 3rd party support available for UL Power engine mounts to fit Legacy Sonex, Waiex and Xenos airframes and for Onex airframes. The Jabiru 2200 engine mount offered by Sonex Aircraft will fit UL260-series engines.

UL Power 260 and 350-series engines may be purchased from Sonex Aircraft, and technical support is offered by UL Power North America.

Rotax 912-Series Engines

Rotax 912-series engines have become popular with some Sonex builders, particularly in international markets such as Europe and South America, and several customers have successfully made their own Rotax installations.

Although we do not sell Rotax engines, Sonex Aircraft provides Rotax 912-series engine mount options for the new line of B-Model aircraft, and B-Model cowlings have been designed to accomodate Rotax engines. Rotax 912-series engine mounts are also newly available for Legacy Sonex Aircraft. Sonex does not provide specific installation techical support for Rotax engines as there are many existing Rotax installation support sources already available.

A note about alternative engine choices: Although there may be other viable engine choices for Sonex Aircraft, LLC airframes, only approved engine installations have been engineered for proper weight and balance and power loading. Specific firewall-forward installation support is only offered for engines installed and tested by Sonex Aircraft, LLC. When installed according to Sonex-provided documentation, the user of an approved engine can anticipate a trouble-free installation proven by thousands of flight hours, as well as full customer support and on-going serviceability.

Customers should not underestimate the vast amounts of time, money, and effort that go into alternative engine development and installation. Any customer choosing to use an unsupported engine installations are true "experimenters". Sonex Aircraft, LLC will not offer firewall-forward technical support for unapproved engine installations. Your choice of an alternative engine may also result in insurability problems. As a potential builder, you must educate yourself on the true impact of your engine choice before embarking on an alternative engine installation. The list of issues that should be considered include but are not limited to: Installation support (cowl, engine mount, cooling), installed weight, reliability, serviceability, impact on flight qualities and useful load of airframe, and availability/cost of insurance. Sonex Aircraft engine installations must not exceed 200 lbs total weight forward of the firewall. Any builder considering use of a heavier installation should take notice of the important information contained in our Gross Weight Advisory (LSA Compliance and Safety) Letter.

Sonex staff have been involved in the aircraft and engine business for over 40 years and we are constantly watching the engine market for emerging products. If a new, viable powerplant emerges which fits our needs and philosophy it will be offered only after it has been thoroughly tested on factory aircraft. If you have any questions about your engine choice, please feel free to contact us.
