|HOW TO INSTALL CLOTH HINGES
I think that I have found
the best way to install cloth (Easy Hinges) in balsa. The hinge does not become as brittle
over time and keeps it's flexibility without giving up strength. It actually increases the
strength of the hinge. I say this after extensive testing. After cutting the slots and
shaping the aileron, rudder, or elevator to a nice rounded shape and before CA'ing them
into place, do the following. Heat up some Crisco on an empty paint can lid (I use a
BalsaRite can) with a small soldering iron. Separate the two surfaces that are hinged
about a 1/16th on an inch. Use a very small paint brush and apply the melted Crisco to the
hinge on both sides. Do not use a lot of Crisco, only enough to coat the exposed area.
Slide the surfaces back together nice and tight and apply 2 to 3 drops of CA to each hinge
on each side. The Crisco helps the CA flow into the slot and more CA gets to where you
want it, in the slot gluing the hinge. If you do not believe me, just test it your self!
The nice thing about it is that the hinge remains very flexible which cuts down on the
servo load which is critical when using miniature servos and also helps the servo to
center easier by reducing the load.
