LT-40 and warped control surfaces
spray the warped parts with some woater and amonia. Appx 10% household amoinia (which is ALREADY diluted) an enough to start having the liquid run off the wood.
Clamp the wood in proper alignment. It will dry the way you clamp it.
Its a good catch to find the warped wood before assembling the wings... it pays off to notice things like that.
After you straghten the wood the wing will be just fine.
