Normally, I wouldn't have posted this, but the girl (wish I would have got her name) at Tower Hobbies was so nice/cute. I am building a Goldberg Tiger 60 purchased from Tower Hobbies following RCKens LT40 basic building technique (my first build in 30+ years). Upon inspection of the wing parts, I found one of the ailerons was quite twisted, in a couple of directions. I called Tower and after explaining the problem and giving her the part number, the nice girl puts me on hold to talk with someone else (maybe Goldberg?). She comes back on the phone and says "is it the right or left aileron?" I said they are the same part, same part number, quantity of two in the kit. There was a silence for a few seconds, and she says "well, they need to know if it is the right or left aileron before they will ship you a new one". So I said, well, lets call it the right one. She says "OK", and they will ship it out to me, and thank you. About 10 days later, my new, straight, right side (LOL) aileron showed up at my door. Thanks Tower/Goldberg!!!!!!!!
