Modern stunt planes are very similar in design.
Can you point me to an article or post that gives ball park numbers for a modern stunt plane.
Ex: Flap elevator distance? Drive washer wing distance. Flaps % of wing area? Horizontal stab % of wing area? Elevator % of tail section? Rudder % of wing? Etc? ???

How could you miss this http://stunthanger.com/smf/index.php?topic=31434.0
The quick answer in less than 10,000 words is NO. Some like 10"-11"--16" HB~>

Perhaps an even better tidbit that's in that thread (and many others) is the right set of numbers to ask for, and how important they are. There's a lot of substantive discussion of this in the design group, if you read through it.

One answer would be a Trivial Pursuit-- not just a few measurements, but the whole package.

There are many great stunter kits now available. Those few of us who still design and build from scratch are mostly mentally challenged, anyway.
Best advice: Look around what others are flying. Then order that kit.

John,
The short answer is that comparing to the Nobler, moderns ships tend to be bigger. The major changes are longer tail moments (flap hinge line to elevator hinge line) have increased by 10 - 12%. The area of the elevator/stab have increase from 18% up to 22 - 24% of the wing area. These changes allow the CG on a modern ship to move back to around the 23 - 26% of the average wing cord. Last thing is the power level is 25% more for about the same weight (larger diameter props can be used and the bigger tail area lets it turn). Most classic ships could hold there own with just a change to current power plants but would also benefit from the other changes also.
Best, DennisT
