I started building the Mikeys RC trainer with some dollar tree foam I picked up.
I was laying it out on the foam, and realized the wing is longer than the 30 inch piece.
Nope, no problem at all. This plane was also made from Readi-Board. Two peice wing with winglets, all glued together with gorilla glue. Just be sure you have a good tape holeding the halfs together till what ever glue you use dries. The FT Cruiser is also made with a two part wing to make its 52" wing span from Readi-Board.
The foam you get from Dollar Tree is made by R.L. Adams Plastics and is sold under the name "Readi-Board" the tags used to say it but if you look on their site it still lists it as Readi-Board
