Thomas,
You at least understand the problem. The desire for low-or-no rebound is at odds with the strength issue. If you articulate the gear you can improve it, but it gets expensive quick.

I thought so..
The idea is to keep the speed, but make the BD-4 more rough field capable, shock absorbing without too much rebound would be the ideal thing:
Like the air-bumps on Baja-Racers....

Thomas, The biggest problem there is, "Does not or barely rebound". The different weights is also tough, but with carbon you could design strong enough for a 4 seater but it would be a bit stiff when unloaded.

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...?).
Already thought about "Airbag"-suspension, a la Hornet (Challenger-derivative...)
At the end the best designed gear does not need any adjusting..
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
aluminum. After ripping them completely off the landing gear box, they
are in perfect condition.
