45) Put the aileron in its proper place, and tape there with
packing tape on the bottom of the wing. Lay the wing
on the edge of a flat table and sand it so that it
matches the rest of the wing properly. Apply tape to
the top side of the wing, then remove it from the
bottom side.
46) Notch the wing edge where the control horn is in the
way. Cut the notch so that the aileron may bend all
the way down (about 30º).
47) At this point we want to thread the servo lead into the
wing so that it is available inside the fuselage later.
It’s much easier to do this now than it would be after the wing is joined to the fuse.
Remove the servo connector from the leads. Note the orientation of the contacts in the housing. You will
need to reassemble it properly later.
48) Make a hook in a short (6” or so) length of light piano
wire. Insert the piano wire through the hole you made
earlier (Photo 36) out to the aileron hole. Loop the
servo lead around that hook and tape it to hold it fast.
You should now have it as shown in Photo 40.
49) Pull the servo lead back out of the wing. Restore the
connector to its prior condition, and repeat for the other
wing.
50) Place a small scrap of 1/8” square balsa into the wing
as shown in Photo 41. This will serve to level the area
where the aileron servo will fit. Insert the servo
loosely.
51) Hook up and turn on your receiver and transmitter. Set
your radio system up with neutral aileron trim and the
stick in center, using a Y connector to attach both
servos to Channel 1. Adjust the position of the output
arms on the servos so that both arms are either
perpendicular to the wing bottom, or so that they are
slightly (1 tooth) toward the leading edge from center.
It is important that both are the same!
52) Remove the excess control arms and fit the servo down
against the 1/8” square stop you made above.
53) Drill the hole in the aileron control horn to that it
accepts the Micro EZ connectors. Use a sharp bit and drill carefully so as not to damage the wood. A
spare horn is included in the laser cut sheet just in case.
54) Insert the pre-bend end of the aileron pushrod into the innermost hole on the servo output arm. Install the
EZ connector into the aileron horn and assemble as shown in Photo 42.
