What is the adhesion characteristics of the resin to Nidcore as it is "plastic"?
Could Nidcore be covered one side only as is done with the foam on the wings.
If I were to use Last-o-foam to build the wings, 1/2" covered one side only as plans call for, (I think I used 1" 30 years ago) , weight of one cubic foot translates to 4.5 pounds per 24 square feet of wing area. That should translate to about 10 pounds per wing or 20 pounds total for the wings. That seems high for some reason as I recall a 2'X8' sheet seemed to weigh very little.
What about Divinycell foam? reasonable price? https://fiberglasssupplydepot.com/divinycell-pvc-foam-core-h-80-5lb-density-plain-sheet.html?attribute_values%5B300%5D=1299&gad_source=1&gclid=CjwKCAjw68K4BhAuEiwAylp3klZ_W6LL-hNZ6kxusqe7DKyawrySS9Jr-N3B2hVS1AnXfamnUmi5-xoC9PcQAvD_BwE#product-details-tab-description Prices have sure gone up in the last 30 years. 🙁 Larry Flesner -- KRnet mailing list KRnet@list.krnet.org https://list.krnet.org/mailman/listinfo/krnet
