I've also run into problems with the Post Office and UPS and the size of the current box that handles 4 sets of any of the cores I've worked up except for the Giles and other wings with over a 13in. chord. An eighth inch difference, just from how the box folds, can knock the price from $10 to $70!
So, I can size a custom box which will fit everything under a 13in. chord and cost something like $4.50 a piece. That would up the cost of all the Quad wing types about $6 to, say $50.
The single sets would still be $15 since they use a 24 x 14 box already.
The alternate is a stock box, specifically one that is 24 x 14 x 12. It will only cost $2.45 but it will hold even larger wings if needed. It would hold 3 sets of cores with the price $35
Please let me know what you think. Post a reply here or email me direct.
