that's going to be pretty cool, did you ever think about Vacuum bagging it? I use to Bag wings for gliders, they would turn out very nice.
Looking good
Was curious what SPECIFIC foam was you are using ?Years ago 8+ .... when I was Building and racing R/C racing boats we used a similar High Density foam that was super firm, sandable and able to be glued too with epoxy. We would skin the foam with 1/32" marine ply making for stupid light weight yet strong structures. * Typically Sponsons for the Hydroplanes etc ...So I'm thinking a skin of fiberglass cloth ( VACUUM BAGGED ) using a WEST SYSTEMS finish grade epoxy would be SWEET !Tho that very well may be @ what your planning all along.Scott S
