Nice! Yeah when I started shopping originally, I was only familiar with RV's. Then I started looking at the RV-12 since it's cheaper than the bigger RV's, and that ended up leading me to Sonex. The Sonex is way cheaper than an RV-12 and it can do aerobatics, which I really wanted.
I think I'll start with just the tail too, for the same reasons. Also, if you go to the workshop and then buy a kit later, they'll take the $200 you paid for the workshop off the kit price, so it's effectively free. I'm pretty sure if you already bought a kit they'll let you just show up and do the workshop for free too.
Yeah, from what I've read (and what they said at the workshop), they both fly identically, so it's just up to what you prefer as far as looks. I'm leaning towards the Waiex, just because it's already a weird looking plane so I might as well go all the way weird.
