I have a few R/C Model airplanes that I want to sell over the net. They are 40-60 size aircraft with 5 - 6 foot wingspan that are alreadybuilt. I see lot's of people selling built planes on the net and they are charging $30 - $45 for shipping. I would like to know how they are doing this? I calculated the shipping charge on USPS and also UPS and FedEx and the parsel post rate is over $100.00 for an oversize package large enough to properly ship a model. Not to mention that It should be shipped in 2 boxes. 1 for the wing and 1 for the fuselage. I don't even want to think about what it would cost to have a special box made on top of it. Any suggestions?
