Gorilla Glue Tips
I use Gorilla Glue to join the EPP with anything. This glue foams up when it comes into
contact with water. First make some puncher holes in the EPP so the glue can grip the EPP.
Wet with water using a small paint brush. Apply Gorilla Glue to both surfaces and spread
with a small stick. Try and force the glue into the puncher holes. Push the 2 surfaces
together, remove as much excess as you can. Hold together with masking tape until
hardened. As the glue foams it will try and expand and push the surfaces apart.

Wing
You may need to trim a little off the trailing edge to get a clean sharp edge that’s a little
thicker than the 2mm ailerons. I removed a little after covering the bottom with film so
there was a straight edge for the ailerons, and then added the top film.
Start by rounding off the wing tips using sandpaper. A 30mm diameter is a good guide. Make
sure both wings are the same.
Make up a small peg (eg carbon or bamboo 2 mm diameter) about 40mm long so that 10mm
can stick out the front of the wing and plug into a hole in the EPP fuselage. It makes sure the
wing is centre. Cut a half channel in each EPP wing root to take the peg.
