I really like Don's suggestion, and would propose a couple of small
modifications to it.
1) I agree that 3.1 grams for mono- pennyplane is a good, yet
challenging target for
someone starting in indoor modelling, but A-6 is much smaller. How
about eliminating the wood size limits, and in their place use a 2.0
or 2.5 gram mass limit (like Barry had). This would be called
the "A-6 Intro" class.
I would definitely NOT rule out a shaft in tube prop-hub. It allows
the beginner to easily explore the effect of prop pitch, a rather
critical concept to learn about.
2) Using the evolution of the pennyplanes as a model, the 'A-6
Intro'
would be followed by 'A-6 open' which would continue the 1.2 gram
mass
limit that is currently used, but eliminate wood size limits and
perhaps allow plastic film, which is easier to work with than
tissue, but not common in a beginner's toolbox.
Now that S.O. season is done for this year, and I'm almost done
grading the last of the make-up labs, I might actually get to work
on one or two planes of my own!
After reading the recent posts, I'm building a new A-6 instead of
finishing the ministick I started before school and S.O. took over
my life for the year! Thanks for the nudge, guys!

to
be 3.1 grams I think to be a true beginner event.)
