To Whom It May Concern,

I teach high school physics and engineering. In the past we built A6’s
in class and used plastic covering as it was a) cheaper, b) easier to
apply and c) did not wrap surfaces. I am no master builder or flyer by
any stretch. We were able to build in the 1.3 to 2.0 gram weight
without too much difficulty. My students LOVED flying them in the gym.
There are still some in the rafters. Some tried to build to the rules
with condenser paper and gave up. We built A6’s because we could build
and test many different designs cheaply and quickly. Penny planes are
bigger, and the props much more labor intensive. Too much time and
heart into each model.

Consider two categories paper or plastic?

Jerry,

Even with this same paper, it is near impossible to build an A6 down to
weight.
I have 3.6# fuse/tailboom. 3.9# ribs. 4.1# spars. 3.6# for prop sheet.
My model is still 1.3 grams.

This is what we want beginners to start with? $50 worth of wood ordered
from Nick Aikman?

If we could knock 200mgs off the covering by using OS film, we'd
actually be able to use hobby shop wood and still possibly make weight,
like a beginner would.

I'd be far more likely to point beginners to an LPP anyway.
Far easier to build and get close or even under.

Regards.
