The Stinger is a great old airplane! A couple of things you might want to improve on is updating the cowl to a fiberglass one for durability and replacing the ABS plastic rear deck with formers and sheeting or stringers. The ABS parts are so heavy (though functional) but they detract greatly from the airplanes performance. Anything you can do to eliminate excess weight will reward you with a much better flying airplane. They fly well as designed but fly so much better when lightened! The G-62 is still a good choice but one of the modern 50 - 55 engines coupled with a lightened fuselage would greatly improve the performance. You would remove well over a pound of excess weight with just those two changes! Enjoy your stinger! I wish I still had one!
