I can assure you we spent a lot less than $500.00/sheet. I arranged the purchase about April last year, I have receipts and I pretty sure the cost was closer to $320.00 per sheet.

But it is only 3mm thickness. I think there is a mix of RC model Airplanes, Aerospace and Boat building here, everybody is used to different thickness for their applications. My problem with most vendors is, they rape you on the cost of these materials and/or the lead times are to great to make it a viable option this late in the game.

What I don't understand is why nobody is talking about end grain balsa instead. It's so strong and I would bet it's stronger than Nomex, sure it's a bit heavier, but it's commonly available and this is competition is more about being "Industry Strong" than "Aerospace Lite".

If you want to make some of yourself, I can tell you how to make a precision planer, using a std mill.
