I made a mistake and have no idea how, but I built a wing that was supposed to be equal panels but as it turns out, the outboard wing ended up being 3/4" longer than the inboard wing. What kind of issues might this cause and how can I offset this error. Is it that critical?
Thanks you,
Mike

As A story I heard about Dennis Adimisin, he wanted to build a plane and started by making the wing. Big Art(his Dad) came home and looked at it and proceeded to destroy it. He then sat down and started coaching him on the selection of materials and the building of the wing. If you want a symetrical wing panels do you have enough room to slide it over to center the wing in the fuse? D>K

I now use equal span wings but my Music design and a couple others INTENTIONALLY used the outboard wing panel 5/8 to 3/4" longer to achieve approximately the same thing we now do by making the outboard flap a bit bigger or adding an outboard flap tab to help lift a bit more tip weight. In answer to your question-don't worry about it but plan to add 1/4 to 3/8 ounce more tip weight. Also consider the outbound wing is flying a bit faster than the inboard panel. Drag develops about four times faster than lift. Therefore you'll have a little more drag on the outboard wing helping line tension under all conditions..........the added tip weight is nothing to worry about.

Find the centerline and offset it inside the fuselage. Already cut and mounted the flaps? .... Never mind.

Several guys are advocating more are for flap and wing on the outboard side.

Thanks guys. I thought I had mounted the wing in the profile fuselage and had he same inboard outboard measurement but did not. I was hoping it would not be that big of a deal and sounds like it isnt. Again thank you for your input. I will make adjustments as necessary. What bugs me the most is that I still cannot figure out how I did it.

It has an acronym, "CFS", which stands for "Cranial Flatulation Syndrome". Or, commonly referred to as a "Brain Fart". There is no known cure, and unfortunately, the condition advances with age.
I assure you that you are not the only one that is experiencing CFS.

Thanks Andre and unfortunately, you are correct. Everything takes longer for me to do than it used to.

AND... I just noticed I had one composing my reply to you! I typed "synonym" instead of ACRONYM. Duh. Brain fart right there in front of God and everybody!
