I wanted to fly my Carrera Optimus yesterday but had to find that the surfaces are warped so left and right outside give me a different angle of incidence result.
Is it still possible to save the Styro / Balsa wing by twisting, ironing or whatever?
They do not look that bad but the photo can be deceiving you could maybe weight the wing flat and let it sit for a few days to see if that helps. Or just fly it the way it is probably will not cause much problem just trimming it out a bit.
