I just test flew a Nitro Models Super Stearman for a friend, and it was a royal nightmare ! Im surprized that I was able to get it down in one piece. I think the wings are rocked back way too far in relation to the horizontal stabilizer. My Kyosho Super Stearman fly's great, and the lower wing and the horiz stab are visually at the same angle, but there's major difference on the Nitro Models plane. I bet it's like 10 to 15 degree's difference between the lower wing and the horiz stab. Something ain't right... No throttle, full down, and still climbs ! Yikes ! I managed to get er down safely, but im not sure how. I shook for 5 minutes afterwards. lol
