Hi Ray,

I fly pax only, I think my company, Lufthansa, is the only in the world flying the B747-8 as a pax version.

Have you looked at Jerry Bates website, http://www.jbplans.com, he is a well known scale designer, he is also well known for tackling civilian and uncommon planes.
Kits are available from various kitcutters.
He may not have exactly what you want, but his planes have scale outline, fly well and are relatively easy to build.

I am working of plans for a 1/4 scale Gee Bee Z and have used some of Jerry's design methods.

I know of the Speier Modellbautreff, it's similar albeit smaller than the Intermodellbau Messe Dortmund.
Unfortunately I have found that each year I go to the fair, the area for model airplanes shrinks a little and the others (cars, trains, boats, static models, etc) increase.
Might have something to do with the economic crisis, I'm not sure.

However, there is another fair here that has been combatting this trend with a lot of success, it's called Pro-wing, http://www.prowing.de/

This fair is for rc scale builders only, helicopter and fixed wing.
There are no cars, trains, boats etc etc etc.
This fair is getting more and more popular and will probably be the only fair I will go to next year.

Hmm, that doesn't bode well for the Chipmunk, does it... 

Funny thing, I looked it up, I'm guessing you are talking about the shop called "Speier Modellbautreff": http://www.speiers-modellbautreff.eu/

I thought you meant the fair.

I don't know the shop, will have to take a look.
