I think in one of the old newsletters there was talk about fibreglass landing gear...
Anyone out there with the know how  to "tune" the gear to specific properties?
I like Lynn's idea of using something "designed" like the Stinson gear (need to look that up, any links...?).

Who has the expertise to make/design a glass/carbon gear, that:

Absorbs shock
does it progressively
Does not or barely rebound
Can accommodate different weights (4 seater)

I understand one can play with different fibers, orientation, different resins, etc.
But where to start?? :))

I just tested the durability of the BD style gear made from 7075
