Question: What is Wing Dihedral? Is it Adjustable on a VMAR ARF aircraft?
Answer: Dihedral is the bend upwards at the center of the wing. When you look at a wing with dihedral when it is top side up, the wing tips will be higher than the center. The more dihedral the higher the tips. Dihedral provides stability so trainers usually have more than sport airplanes and pattern or aerobatic airplanes often have none at all.
The dihedral on VMAR models is set at the factory. There is nothing to adjust. The angle of the wing roots and the angle of the wing spar joiner ensure that when the wing is assembled properly using 30 minute epoxy, the wing roots will be flush to each other and the correct amount of dihedral will be built into the wing. |
