Thanks.

Yes AM Supershifter with 2 -21/2 cims, with servo shift
and as Squirrel said the aluminum is really 1/4 pultruded fiberglass

that honeycomb material looks like that strong, lightweight material that Boeing sells when they want to dump stuff. I saw it or a similar material in Washington and many Electric Car teams use that material as a substitute for fiberglass.

It looks like corrugated cardboard to me... I have some real thick cardboard sitting around in my room (looks similar to that material), and its actually pretty strong stuff. My father and I experimented with putting polyurethane on some, and it made it a good deal stiffer, too; cardboard's performance is nowhere near carbon fibre, fibreglass, Kevlar composites, etc, but it is surprisingly strong given its relative low cost and weight.
