About

I built N254MM with assistance from friends and family in 2008.  I made decisions while building to make a very efficient and light RV.

I've helped paint it, done a big panel upgrade to G3X, added a good comm radio.  Then I sold it!

... not the end of the story.

The month after I sold it I reached out to the guy I sold it to and asked if there was an opertunity to buy it back.  He said yes, but I'd have to wait a couple years.  Well, this Spring, he was ready.  I sold the RV-6 I was working on and took possesion of RV-4 N254MM again.


And flew it to Oshkosh 2017!  Life long dream, but I realized, I had a "mediocre" at best RV.  Which kinda bummed me out.  The problem was all "fit and finish".  I've been so busy with life and flying, issues have built up over time and need to be addressed.  I don't want a sub-par RV, just a disgrace.

The last few months I've taken some time to fly it generally and man..  With all it's nagging issues, it is a phenomenal aircraft and flys so amazingly well, it's worth improving.  Along with the time flying, I've taken time to think about what I'd like the plane to become.  And... I want to realize the origonal goal.  A maximally efficient RV.
