Anthony Scott 2 Posted November 27, 2019 Share Posted November 27, 2019 Many years ago I used thin artists' card & Copydex successfully on several medium size planes. A colleague swears by brown paper & his Spitfire is a work of art. Quote Link to comment Share on other sites More sharing options...
TigerOC Posted November 27, 2019 Share Posted November 27, 2019 I have been building balsa sheeted foam core wings for a few years. Most are smaller 1.5m glider wings. These are sheeted with 1/32 hard balsa. The process I use is to coat the over size balsa sheet with Lumberjack 30 minute polyurethane glue spread thin with a card and spray water lightly on the foam core. The wing is sheeted and then placed back into the wing bed and then into a suitably sized vacuum storage bag. This is then weighted on a very level surface and the bag vacuumed. This is left for an hour. My experience is the sheeting is very well bonded and I have not yet had a failure under load. On bigger wings I use 1/16th hard balsa. I have 32" bow and power it with a 4S lipo which works really well. I have a switch on the bow. Quote Link to comment Share on other sites More sharing options...
