THIS EXPERIMENTAL GLIDER HAS A STOWABLE 2 CYCLE ENG MOUNTED BEHIND THE COCKPIT. WHEN THE ENG IS STOWED THE GLIDE RATIO IS ABOUT 40:1. WHEN THE ENG IS DEPLOYED BUT NOT RUNNING, THE GLIDE RATIO IS ABOUT 10:1. WHILE RETURNING AFTER A 4 HR AND 50 MIN FLT THE PLT DECIDED ENG PWR WOULD BE NEEDED TO REACH THE ARPT. HE DEPLOYED THE ENG BUT IT WOULD NOT START. AN OFF ARPT FORCED LANDING WAS NECESSARY AND THE ACFT HIT A TREE.
