I want to get some ideas from any experienced stick builders out there. I just completed two wing halves of a BTE(Bruce Tharpe) Venture kit. With a flat board and best effort, somehow one wing is twisted just a bit( 1/8" ) from one end to the other. The wing is built using only balsa ribs, two hard wood spars and four balsa stringers(subspars). It is glued together using medium CA. What methods are available to remove this slight warp? I have placed the wing on a confirmed flat thick glass table, misted the wing with a water mister/sprayer and used small weights to hold it perfectly level. The slight warp was still there when dry. Any good ideas for correcting such a warp?
