I
made ailerons out of 4 mil coroplast but you can use balsa or
foam wrapped in tape, it's up to you. I would recommend against
making them too big because of flutter off a high start or in steep
dives. The design shown in Figure 12 came after trimming down
some standard Zagi style ailerons to reduce the flutter. They are
3/4" wide near the control horns and 1-1/2" at the widest point.
They are attached using packing tape on both bottom and top.
The
servos should be installed as far forward as practical to help with
balancing the center of gravity. Cut a small square, 3 cut, hatch
in the foam to install the servos, if there is a piece of foam or
something under the hatch, just chop it out. I have used both double
sticky tape and (you guessed it!) hot glue to stick 'em in. The
battery pack I used is the 4.8 cell flat pack and it nestles up in the
nose quite nicely, with the receiver just behind it. Cut slits in
the foam to provide access to install the battery and receiver but try
to keep them as small as possible. After everything is installed
and glued down, just tape over the slits with your friend Mr. Packing
Tape.
Slot the foam for pushrod exits as appropriate for the
height of your control horns and pushrod type. Attach them to the
top most hole in your control horn. Test for free movement.
