lbianchi,
hello--got some info for you RE the Monocoupe your woriking on--obviously you are aware of the Russel Williams site and the great pictures he has on the of the older aircraft/including several models of the Monocoupes--Yes there are different models and each has some particular aspects about it you should know about-- a couple of posts back you pictured two different panel-NEITHER IS Correct for your Coupe. The Kangke Monocoupe is modeled after the model 90A Monocoupe-the (almost) last model of the company line.-and look through the Williams site again and you will find at least 2 correctly identified 90A monocoupe panels -(one with black crackel finish -another wood one from Bob Coolbaughs stylishly painted "Bird"like color4 scheme-its a model 90 )-the ones you chose are model 90 or model 110 style panels("simplier"[less instruments] and earlier models than the 90A).
It's interesting that Kangke chose the paint scheme they did -it's similar/very close to one that is actually on a Monocoupe Clipwing (a 23' span rather than the normal 32' one on the standard 90 & 90A)... located in Florida-US--N number- 101H- (similar to the N1161-black & orange one on the Williams site)-the Clipwing Coupes are a whole nother story....either way a very attractive color scheme and Pettit is right pin striping adds tons to the over all look !!
so the Monocoupes were two seater airplanes-side by side like a good sports car of the 50's era...and a tight fit only some 40+ " from side to side--the 90A s were a little wider---sometimes there was only one stick but most often there were 2-and they were either connected via cables or later a rod up the inside of the cabin area right by the pilots left knee to a bell crank mounted on the rear of the front spar-with cables running out to the ailerons on both sides-- behind the seats and between the small side "D" windows was a flat."shelf "unit going back about 18" to 2' to a panel that turned upward and stoped as it reached the rear most top of the cabin area--

the windsheild is easy on the real planes they were simple wrap around units going from the post at the front of the cabin door up and over the nose panel and back around to the the other sides forward post--only tricky part is where it over laps the center forward part of the wing LE.--if you need a pattern I could make one up for you and scan it and sen it via e-mail-if you'd like --think I still have one here from one of my Monocoupe models.

Hope this may help clarify your questions-sorry I'm so "wordy"---
Regards
A.L.Lockrow/aka Clipwing (like the model 110 Special Monocoupes)
