I've got 50+ flights on my Sig four Star 60, and of the several "seasoned" RC pilots that have flown it, all have commended it on it's great flight characteristics, and how honest an airplane it is. And my Hobbico Avistar was good, but not great, and it flew quite well. BUT.......the Graupner Super Air that I had was an example of how ALL ARFS should be constructed. Perfect, really. No way I could build it, or cover it that well. Down to the finest detail. Just wish it hadn't gone to that big 'ole hanger in the sky.......
