Let me see if I get this straight: you order from Tower Hobbies and recieve a kit with a smashed wing. They want you to spend between 10 and 15 addional dollars, plus time, gas ect before they'll consider sending you a new one? That's absolutely pisspoor customer service. My local dealer has complained recently about the way Hobbico/Tower/GP has treated them lately. It reminds me of the big 3 auto dealers losing perspective on quality/customer service in the 70's and getting eaten alive by Honda and Toyota.
Customer service is everything. In the past I've had good service from Tower but it seems like so many people are complaining lately. It makes me uneasy about ordering from them again. Horizon Hobby has never been a problem and Hanger 9 Kits rock. Perhaps you should look at one of them.
