Joining FoamBoard


New member
OK biggest sheet I could get of faom is A1 ( 33" long) but my wing plan shows wing as 990mm (38") how do I join the foam to make the wing?

THe model is a Krusty RC which has a one piece wing.

Is each side of the wing 38", or is the total length 38".

It's a common FB build technique to use packing tape to to hinge the bottom wing surfaces together in the center and then hot glue the sections together when setting the dihedral. Then adding more tape to the top surface joint for reinforcement.

See any of the many FT build videos for planes with similar lines as that model.
