have already dismantled two other models because I am a beginner. now with the duet I could finally learn to fly it. The plane flies quietly and simply. I can now even loops and the landing is almost perfect. have the aviator stuck a few times (UHU POR) and it flies anyway as the first tag.geklebt just because I'm a go-getter and Ziehm union wind also fly. a recommendation for any beginner.
