Build notes for the FT Mighty Mini Arrow

These notes are a condensed version of the FT Arrow build video.

Wings

Do an "A" fold on the spars and glue, stop 15mm from each edge. Use a triangle to make sure the spar folds are perpendicular.
Open the servo hole.
Cut the bevels, double on wing and single on elevon (on the elevon side).
Add a thin ribbon on glue on the bottom of the elevon hinge for strength, and scrape almost all of it off.
Remove servo pocket from the wing.
Fold the wing with the bottom on top, to curve the leading edge without crinkling the airfoil score cuts.
Cut the side pods if you aren't going to use a center pod.
Glue the side pod hinges.
Cut the main pod space on the top of the wing.
Skewer the wing score cuts.
Line up the spar's servo hole onto the wing and glue onto the top side.
Glue the airfoil's score cuts and fold the wing so the score cuts are glued up.
Cut the excess spar.
Probably put the servos in now, to avoid having to make a hook later.
Glue the leading edge, bottoms of the spar, and the end of the trailing edge, and press closed.

Tape the wings together at the bottom, glue them together in the middle, lay them down and wipe the excess glue.
Cut the excess edge of the nose.

Pop out the foam tabs on the wings, where the center pod will go.
Pop out the tabs on the center pod.
Do an "A" fold on the bottom plate.
Fold the little edge of the top of the center pod over (and/or add tape).
Glue the center pod on. The backs of the wing should both be at the same height. Note that still be open/exposed, not glued down. FT leave them like that, but I like to close them up with some tape at the end so junk doesn't get into the wing.
Install the control horns and servos (I use epoxy for the control horns as they tend to get ripped out with just hot glue).
Use the reflex checker foam to calibrate the wing's reflex.
Add a ziptie to the control rod so it doesn't bend.

Install the motor onto the power pod and install the power pod. You probably don't need to glue this, just make sure it's tight.
Remove the foam from the sides of the nose.
Do a "C" fold on the back bit (and probably add some tape).
Carefully bend the nose.
Test fit it and glue the front part.
Use more tape to secure the front and sides.
Add some tape so you can pull the top open.
Add some glue to the bottom of the top hatch so it catches and secures on close.

Only cut the top part of the wing, parallel to the bottom.
Line up the reference line on the winglets and glue (the front tip of the winglet should be flush with the leading edge).
