Sure, but for N-registered aircraft it isn't a regulatory-compliant install if it's class 1. (mind you, FAA doesn't need one in a glider at all, so there's that) > Trig stuff at Craggy Aero: > http://craggyaero.com/trig.htm believe it or not (and it's crazy, I know!), I found Aircraft Spruce cheaper. TT21 in the post-Thanksgiving rush for US$1803, which, at the time, was about $300 cheaper than Craggy Aero. Pays to shop around, anyway. - mark _______________________________________________ Aus-soaring mailing list [email protected] http://lists.base64.com.au/listinfo/aus-soaring
