gfpierce,
Thanks for the answers! Yes, that helps.
On the engine mounting-bolt spacing, I mean the space between the blind-nuts on the firewall (assuming a person wasn't going to use the factory mount). I guess what I'm really asking is with the RCS140's rear-induction and different throttle and choke geometry (come through the firewall inside the bolt-pattern), will the mount that comes with the ARF work? I used a Dubro 688 aluminum mount on my other RCS140 install.
It has a wider stance that I thought! That's a good thing. I've seen the GP Ryan STA fly and it seems squirrelly on the ground, with a tendency to tip over and scrape a wingtip now and then. Sounds like the GeeBee should be better.
I've been thinking about the tailwheel. Not very scale... though I don't know if I want a wheelpant on the tailwheel. That would be too strange.

It's just that it looks so small in the pictures and I'm worried about it holding up on our rough grass field.
Thanks for the landing-gear-strap idea for holding the wing together! I really want to keep it removable, as I don't have an easy way to transport an 82" wing in my truck.
Anybody have more pictures?
