I was part of 190 a few years ago but wasn't any builders really doing much, plus there was no EAA Inspector which was I was looking for. I didn't have my shop done back then so I ultimately sold my kit but after helping my friend from One-Legged Avn work on his 750 I decided to get back to it. I need to get back flying something for my sanity and my shop is done. If anyone would like to come by and talk shop or help on the RV10 hit me up.
I'm in the same boat, starting on a RV15 (first time offender), looking for fellow RV builders. Good info in this thread, did not know about TVRVBG, thanks for posting.
Right now I'm cleaning up my garage, getting tools and doing lots of research while I wait on the wing kit. Should be any day now, it shipped out end of last week.
