RE: Where would I put my CG?
Don, I really appreciate the offer, and I'm going to take you up on it. This is the first biplane I've ever even been near (other than a ride in a full-size 2T1A when I was 16 - 44 years ago) and with this being swept-wing, I'm lost. If it was a straight wing (like a Jenny or something) I'd just go with my normal practice of averaging the 2 center spars (which normally gets me pretty close), I'm sure that's not going to work with this lady though.
Everything I've gotten on her so far: Wingspan (both) 56.75" constant chord (both) 8"
TOP WING (swept)
Nose to LE @ center = 5.75"
Nose to TE @ center = 13.75"
Nose to LE @ tip = 9.5"
Nose to TE @ tip = 17.5"
LE @ center to vertical stab LE = 25.25"
TE @ center to v-stab LE = 17.25"
LE @ tip to v-stab LE = 22.5"
TE @ tip to v-stab LE = 14.5"
LE @ center to horizontal stab LE = 24"
TE @ center to h-stab LE = 16"
LE @ tip to h-stab LE = 23.5"
TE @ tip to h-stab LE = 15.5"
BOTTOM WING (straight)
Nose to LE = 10.5"
Nose to TE = 18.5"
LE to h-stab LE = 19.5"
TE to h-stab LE = 11.5"
V-stab LE to rudder TE = 7.75"
H-stab LE to elevator TE = 8.75"
V-stab LE is 1" behind h-stab LE, TE's are at the same distance (she'd stand vertically on her tail)
Landing gear axles stand about 1.5" behind top wing LE
My numbers may be off a tiny bit but I'm pretty sure they're all within 1/8" of being right. Hope they help you. Once again, I appreciate your taking the time to do this.
