Re: Belly Pan Lightening Holes

The diamond pattern contains straight lines running corner to corner, which act in pure tension/compression diagonally across the bellypan to add torsional stiffness to the frame. The hexagonal pattern's members doing this job are a bit zig-zaggy.

Realistically though, this is a nit-picky design criteria. Any bellypan is going to significantly increase torsional rigidity, and I'd say that this choice can be safely made purely based on actual weight lost, aesthetics, etc. There are much more important things to worry about on a chassis design.
