FYI, somebody I know went through the SIG plant tour and saw pallets of dope from Randolph...thus, SIG = Randolph. If you go to your Randolph dealer, they will mix you a quart or gallon. Of course, they use 1:1 scale colors...paint chips are Cessna, Piper, etc., not SIG, but that's only a minor problem. I'm pretty sure SIG would have just selected one from the standard charts...but which?
Check out the "VUM-18" if you want a Hungarian stunter. Pete Peterson had one (Enya .45) and liked the way it flew a lot. I always thought it was a homely design, but it's certainly not going to be mistaken for a Nobler!
My friend in OZ (Dave Simons) had an early (pre-Shark) Yatsenko "buy-tech" model with the Retro Discovery .61, and had some "Fox Burp" complaints about it. He shipped it back, asking them to rebuild the nose and install the engine sideways, but it came back mounted 45 deg. off inverted. It then ran fine. One of those deals!
