GJ and Tom, went up last night and did a engine off glide back into the airport from 3000ft agl (dead stick landing)
60 knts / 70mph is about 1050 fpm +
50 knts / 60 mph is about 900 fpm
42 knts / 48mph is about 860 fpm
thou my wings are a tad shorter, as for glide ratio form the first experience i had was somewhere around 4:1 to 4.25:1 from what we can work out for the video
even thou i did do a heap of drag stuff since then (wing struts and jury struts) - i have more to do
