You're right, if you start taking the bus apart you will not be able to use it for the next few (maybe more than a few) years. If you have definite ideas about what you want a bus to be then start from scratch. From what I've read on this forum that is much easier.
I hate taking things apart. I've had my TR4 apart for four years. I could have been enjoying it and that wasn't even for a restoration, it was just for a thorough paint job!!
I bought my bus already converted because I'm too old to start from scratch, I want to enjoy it while I can.
I have an Aeronca Champ that could use some airframe work; however, I see from your website that I am a bit out of your league!! I stopped there once for avgas in my Stinson 108 and brought everything to a halt while they figured out how to fuel such a small airplane.
I know what you mean about your TR-4. My Quad 4 Sunbeam is going on two years now and it all boils down to time. We are not at all out of your league with your Aeronca I have built a couple of Champs in my shop. The Starships we fell into a couple of years ago and we do many different types of aircraft. I have a Maul and a Bonanza in the shop now for annuals. I love doing fabric and my fabric work is in the Smithsonian on Patty Wagstaff's Extra 260 that I recovered. I would be honored to help you with any airframe work you may require. My contact info is on the web site.
You may have our airport confused with Pinal Air park where all the airliners are stored. We are south of there and called Marana Northwest Regional.
