RE: Balsa Sheeting Question
The ARF wings are covered in Monokote, Ultracoat and a varied amount of other coverings, once again depending on who made it. Some of them have a stick on covering like shelf paper. As for sheeting sizes, I would stock 1/16 and 3/32 for the bulk of it and maybe some 1/8. Most wings in the 40 to 60 size range use that thickness sheeting. Good Luck, Dave
