I suggested many years ago ship the products by rolling the wing and insert all in a tube to ship. The problem is the wing has carbon inserts and can not be rolled properly. Don't expect Sean to have some custom build boxes for delivery since those special size boxes will cost a lot from paper box manufacturers and they accept minimum quantity for each custom size box order. Figured it out, Flappingflight is a two person operations out of Cody, WY foothill.
Now a day, I guess China is the only place you can get cheaper price and adequate packaging, but, guess what, not enough quantity to attract them into this market...........yeah, eventually someone comes along with a better, cheaper widget........who will be that, you ?
