Watch some exciting in-flight video of a recent trip in and out of Elk River, Idaho and the beautiful surrounding terrain.

Hear the Bull Moose start up and ride along for some local sight seeing with photographer Erik Johnston.

Taking The Murphy Moose to another level in Power, PERFORMANCE and Style

We have now completed the latest stage of R&D in our exclusive LS3 Aircraft Engine Package with data logging to provide more precise fuel/air mixture ratio information.

The Concept

We are pleased to announce two important developments. Firstly, we have just acquired the direct ownership of the PSRU gear box we use on our LS3aeroengine Packages. It was formerly known as the "CAM 500" and will now be presented as the LSaeroPSRU. We will now be producing this high quality gearbox in the US to help much with timely production and delivery schedules. We have recently developed a mount point upgrade to the LSaeroengine installation to provide a significant increase in strength to manage the high thrust loads our engines develop.
We have also just formed LSaeroengines, LLC through which all of our engine packages will be marketed, sold and delivered.


We are able to also provide LS3 ENGINE PACKAGES for Legend, Titan T-51, Bearhawk, Aero Comp, CYCLONE, Experimental Wilga, Experimental Helio Courier, and other custom backcountry and high performance aircraft.

LS3 Aircraft Engine, LS3 Powered Aircraft, LS3 Murphy Moose, LS3 Aircraft Engine Conversions, Corvette Powered Airplane, LS3 powered Bush Plane, , LS3 Moose, SDS, Race Tech, Bull Moose, Simplified Digital System, SDS ignition, alternative aircraft engines,  aircraft auto engine conversions.

See the recent flight review and testimonial feedback from noted backcountry pilot Herb Millhorn in the Moose Tracks page.  Thank you Herb!.

The concept and motivation behind MooseMods is simple:  Take a well designed airframe and focus on powerplant development and airframe enhancements for:

  • Improved performance with greater engine power and fuel efficiency using the well proven LS3 engine in a complete FWF package of our design

  • The use of new digital technology for ease of in- flight engine management


  • Aerodynamically efficient cowling for better speed and forward visibility

  • Structural Upgrades for Expanded Airframe Ruggedness and Operational Utility

  • Improved Personal Conveniences and In Flight Environmental Visibiliy……and an important measure of “Cool” thrown in for good measure!
