rv9a building
I'm building one, also have rv6, and imported 4 rv9a kits in one go so anything you need to know just ask. I note that no one mentioned how long they take - it's a massive amount of very detailed work. My advice is keep it simple & buy anything pre-built that you can. You also require a fairly comprehensive set of tools not just a drill and rivet gun. You also need to learn riveting - this is not too hard though. Oh, and just one gripe, if you modify anything the PFA can take an age to approve it & countless additional details etc. - they are an inefficient bunch of old women who who milk the pfa funds without regard to the members some of which struggle to afford the fees etc. I'm aware of at least one jolly to the Vans aircraft factory- how much did that cost?
By the way, the Vans guys offer the best tech. support for any product I've ever had. What an excellent well run company!
