I have been flying John's 303 since last season, in exchange for keeping it in my hangar, and for upgrading the transponder/FLARM with ADSB. I LOVE this glider. Great roll rate from the big aerobatic ailerons. Very docile (no bad stall tendencies), but very responsive. Thermals basically hands off. I started flying it the year after I got my add-on rating with less than 30 hours in a Grob, and it was a very easy transition. I believe the glide is comparable with a flapped glider until about 80 knots, then you start to have a higher sink rate as you push to 100 knots. The glider is in incredible condition, with a beautiful gel coat. Who ever buys this glider is going to be very happy. I am jumping into a JS3 (with Jet sustainer) next month, and I hope the handling and thermalling is half as good as the 303.....
