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?

You can remove it with your sheeting and or covering. Good Luck, Dave

After the covering is applied you can twist it back the other way, when the diagonal wrinkles form you just heat gun them out and it will usually hold.

I'll hold the wing straight up and down, standing on its wing tip. I'll genlty squeeze the covered wing between my knees and use one hand to twist the wing while I iron with the other hand. Its not as hard as it sounds. The wings are still pretty flexible . Just play around with it until the warp is gone. Check it in a month or two, the warp might come back. But if you keep correcting it, eventually it will stay.
