If you shrink tissue with water, the trick is spraying a very fine mist and using as little water as possible. Just barely damp. This results in fewer wrinkles, besides minimizing the chance of warps. The tension in the tissue distributes more evenly. It may be helpful to overbend the surface in the opposite direction of the warp and then let it dry.
When it comes to preventing warps at the lowest possible weight, thickness is your friend. For example, if the tail surface is 1/8" thick instead of 3/32", you can make the parts narrower, use lighter balsa, and come out stiffer, stronger and lighter at the same time.
