I decided to redo my fuel tanks. See here for why. The entries specific to the redone tanks are here.

Just a report that the left tank is leak free and complete.

About E

You just can't beat the intersection of performance and price with many homebuilts. Given my "mission profile", the RV-14 seems to have it all: Best bang-for-the-buck, good compromise between cross country and aerobatics (I don't plan on doing the latter, but the added structural integrity is comforting), can design your own avionics setup, plus you get your own repairman's certificate. I have no relevant experience or special skills relating to such an endeavor. My mean paper airplane folding abilities seem not to apply. If I can build an RV-14A, almost anyone can.

The experience has so far humbled, schooled, rewarded and penalized me. There have been days I've wanted to sell it all for scrap and others when I wanted to build every waking hour. It has challenged my finances, expanded my appreciation of aeronautical engineering, forever changed the way I look at aircraft and found me many new wonderful friends. When this airplane finally takes its first flight, it will be quite a personal feat and the start of a whole new chapter.

My vision for this blog is to be the kind of blog I would want to read if I were building the RV-14A. To that end, I endeavor to provide high quality images of the process, explain my approaches to building, accurately disclose my mistakes, itemize all costs and reference sources for materials and information. It is my hope that this blog is useful to others. If you find it to be, please drop me a line using the "Contact Form" above. I enjoy hearing from fellow builders and aim to respond to everyone.
