I can't help with actual weight/cg numbers, but I can tell you what I did. I asked a couple of people who are already flying the same model a/c that I'm building to give me their firewall to prop flange measurement. Unfortunately, I'm not flying yet, so I can't tell you how well it will work out.

FWIW,
