Default RE: Do wrinkles in wing covering affect flight performance?

Wel I used a slightly higher setting this morning on my wing, tried the hair dryer- too cold for shrinking. Went back to ironing with higher temperature at about 150 degrees celcius. I successfully removed about 90 percent of the wrinkles that you see on the pictures of the yellow covered bottom part of the wing. The material is now very tight, although in the process I accidentally got some colow out of the wing- about 3 to 4 places about 1 mm in diameter. Although, I asatisfied because the wing is like a drum now, makes a banging sound when i touch it. Glad thats over, , but Istill got another wing and fuse coming up, with the tail it will probably be a disaster. But who knows, I am just happy for that this wing is all good. I am visiting an old man's house on saturday, I have got to ask him a couple of questions about my plane design, since he's been building his own planes for about 30 years now and nowadays hes about 80 years old :-S . I think he has a lot to tell me about my plane, i will do my best since on my plane the wings require a hammer and a drill to get my servos out. Damn, I was designing this plane so that in a crash a repair would require another crash on the work bench. Lets just hope this will turn out fine .

Thank you,
