Not to hijack your thread Jacek, but I was just about to post
regarding my Cobra trailer... The fuselage-ramp scissor-jacks just
failed (stripped thread, then the bearing failed under the resulting
load). I've seen some older postings about these jacks but does
anyone have an up-to-date source for small scissor jacks that would
fit? Most retail-store jacks are too big, and I'm willing to bet that
if I go direct to Cobra or one of the glider mfgrs/dealers that it'll
cost me a bundle.

Thanks,
