Moose Mods


Cool night shot by Erik Johnston during recent photo shoot!

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! 

Watch for events in 2019 to view the Bull Moose and the new Super Moose!

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.   


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 next step is to collect some new updated video clips to better demonstrate the performance of what most are calling the well deserved title as "a beast"!  The sound track will give a better idea of the amazing sound it produces...but as many have said...."You've just got to hear this thing!"  Stay tuned!

 OSHKOSH  was a great success.  Thank you to everyone who came by our booth and for the tremendous interest in the Bull Moose and our LS3 engine packages!  I am now back home and getting ready to fulfill orders for this next year.  Stay tuned for the next stage of MooseMods developments!

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

Important Notice:   An unfortunate situation has come to our attention about which I want to make our great customers aware.  There is another company marketing a LS3 aircraft engine package using unauthorized images of the one and only Bull Moose belonging to MooseMods, including our LS3 engine installation pictures.  Also on their site was a first flight video of our prototype in which this company makes the inaccurate claim of having developed our engine package.   That video has been taken down by YouTube.  This individual is inaccurately suggesting that the LS3 engine package MooseMods has developed for the Bull Moose to be of their design and is using our intellectual property and significant financial investment to promote a new business without permission.  It is the case that the individual going by that company name was hired by MooseMods as an independent contract employee for limited work to only assist in the assembly of MooseMods selected and designed components.  There was the clearly expressed understanding that these efforts were for the development of exclusive MooseMods products, use and resale.  In addition to the violation of that understanding, it has been subsequently necessary to re-do much of the work done by this individual due to the defective work performed. Rather than identifying that individual by name, the presence of any images of the Bull Moose identifies them as this noted party.

It is unfortunate to need to address this issue because of the confusion it is creating. We want to simply recommend to our customers to exercise caution in reviewing what is being presented by another company in the market place in the use of the our LS3 engine in aircraft applications.  This noted company has not installed an LS3 engine in an operational aircraft and has no flight testing experience with the engine package being promoted.  MooseMods and LSaeroengines are the sole owner of this FWF engine and related airframe upgrade packages and reserves the exclusive right to market and sell our exclusively owned and developed products.  The company in question is attempting to capitalize on the experience gained at our sole expense and is infringing on our intellectual property toward that end. 

Any informed customer will certainly appreciate that countless hours and major resources are spent in Research and Development of a Firewall Forward engine package, as well as the lengthy process of fine tuning the many components of such a product which occurs over an extended period of time.  That has been the mission of MooseMods and we are proud of what has become an outstanding example of a well proven and tested package that we now present to serious aviation enthusiasts.  Now on to more pleasant topics...
