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

​Bill Wester is a Private Pilot, Instrument rated.  His background is a long time ago far far away he graduated from Georgia Institute of Technology with a bachelors in Computer Engineering, he also holds a dual MBA from UC Berkeley and Columbia University.  He has been helping companies deliver technical solutions for large scale networking, storage and security technologies for over 25 years.  Having a passion for technology and making computers work, he is a natural at understanding complex avionic systems and works to make these systems simple but also utilizing the newest technologies to enhance the reliability and performance of these systems while making the system as low complexity as possible.  Bill is working on his Multi-Engine rating, and has a tail-wheel endorsement as one of his next challenges, and enjoys the constant learning that happens with aviation.​​

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! 

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.
