NOTES ON HORN POSITIONS
Mount the horns so the clevis holes are 1/4" (6mm) behind the hinge line for the
ailerons to give differential and on the hinge line for rudders and elevators.
But on the FLAP horns, move the horn bolt rearwards about 1"(25mm.) from
hinge line and drill the hole for the horn bolt back so that the hole in the flap
is a full 3/4" back behind the hinge line. This will allow the flap to drop almost
to 90 degrees full deflection.
Insert all hinges and check range of
movement, then apply thin CA glue.
As With all ARF Kits, it is essential to make
a thorough check of all glue joints and add
epoxy or CA glue if required.

Be sure to apply thin C.A. glue to both
sides of each hinge. Then pin each
hinge from below using cocktail sticks,
fore and aft of the hinge line. Do not
pierce the top surface.
Also, pass a hot iron over all the film
covering edges, especially leading
edges of the covering to ensure
adhesion, and then seal these with a
clear dope or clear coat using a very
small brush.
