When a wing has less dihedral is it more likely to stall in a steep tight turn?
From : Don Stackhouse An airplane stalls, whether in level flight or in a turn, because the pilot pulled the nose up too far and forced the wing’s angle of attack to reach the stall angle. If it’s a free-flight model, then the person trimming it before flight trimmed in too much “up” and caused the nose to go up too far and the wing’s angle of attack to reach the stall angle. In either case, the cause of stalls is “pilot error”. Dihedral can have a positive influence on the sink rate in a turn on airplanes whose turning radius is relatively small in comparison to their size, such as HLG’s. We have found both by test and analysis that the amounts of dihedral typically used in a 2-channel HLG reduces the sink rate. This seems counterintuitive, but it works. We first discovered this by accident many years ago while developing improved versions of our early Monarch RCHLG’s. We tried one with about 2 degrees less dihedral per side, expecting the performance to improve, since after all, “eve
