Grayhawk: shouldn't that be 330-350 lbs per wheel empty?
My empty
weight is 1030 lbs (Lancair 235 / O-320).
OK, my guess was off a bit for empty. Empty weight does not do much
for evaluating shocks for a fully loaded plane. I finally looked at
an original W & B sheet.
Using the back of the firewall as zero position.
At an empty weight of 1160 (before interior, stuff, etc), I had 424 lbs on
the nose (BL -6.75) and 736 lbs on the mains (BL 37.5) for a single main
wheel supporting weight of 368 lbs.
I didn't do all the weight combinations, so:
No people, full fuel (43 gals) and 47 lbs loaded at the aft of the baggage
compartment (1458 total) had 411 on the nose and 523 on each main
wheel.
180 lb pilot and full header (9 gal) only (1394 total) had 432 on the nose
and 481 on each main.
My guess is that when loaded up to gross, it is more like 630+ on each main
at 1G (bounced landings not considered).
