Composite, spring landing gears are a bit tricky, and often expensive if
carbon is
used. For these reasons we have in general replaced composite gears with
spring
aluminum designs for kit production. Composite gears suffer in torsion

if

you
use UNI or roving, and also in delamination in "bend" radius areas, The
constant
curve "bow" as used in Rutan designs  minimize the delamination problem,

and

they use BI overwrap to improve torsion and protect the UNI. The

effective

modulus
of elasticity is very sensative to fiber straightness. You can probably

save

some weight
and get a lower drag section with composites, but it is labor intensive,

and

subject
to greater variability than metal. if you supply me with more

information I

might be able to steer you to a starting point.  Vance

Hi Vance

Overall width 1550 mm height from axle to top 290 mm flat attachement area
200 mm.
MAUW 990 lb. This will be for a weight shift microlight (ultralight) that
are mostly used from dirt strips, sometime realy bad strips. I looked a
2024 - T6 or 7075-T6 but can't find any in this country. In 2024 it's 5"
wide at the top and taper on the one side to 2.16"

Any ideas would be appresiated.
