5) Clip another R/C Link into the elevator servo arm.
Set the
elevator in neutral position. Mark the servo end of the pushrod
tube exactly 1/8" from the end of the R/C Link. Unhook the R/C
Link from the elevator horn and slide the pushrod tube back out of
the airplane. Cut off the tube at the mark just made, using a sharp
razor blade or modeling knife.
6) Cut another 10" Threaded Steel Rod to 7" overall length. Coat
the plain portion of the 7” rod with a very thin layer of epoxy glue.
Immediately slide the plain end of the rod inside the servo end of
the elevator pushrod tube. Screw at least 3/16" of threads into the
tubing. Wipe off any excess epoxy glue and let dry.
7) After the glue dries, screw a nylon R/C link halfway onto the
exposed threads of the steel rod.
Clip the R/C link into the
elevator servo arm.
8) Plug the elevator servo into the receiver and test the operation of
the elevator. If there is any binding in the movement, find the cause
and fix it now. With full up and down movement of the transmitter's
elevator control stick, the elevator should move approximately 9/16"
up and 9/16" down.
AILERON PUSHRODS
Locate the following parts from the kit contents:
❑
(2) 2-56 x 10” Threaded Rods
❑
(2) Nylon R/C Links
1) Mount a servo in the plywood Aileron Servo Mount, which is
already installed on the bottom of the wing. REMEMBER: Do not
over tighten the servo mounting screws to the point where they
compress the rubber grommets too far.
2) The aileron pushrods are made from two 10" Threaded Steel
Rods. Screw a nylon R/C Link halfway onto the threaded end of
each rod. Then clip the R/C Links into the holes in the Nylon
Aileron Connectors and line up the pushrods with the servo arms.
3) Tape the ailerons in neutral position (the bottom of the ailerons
and the bottom of the wing should be flush).
Then hold the
pushrod wires up against the servo arm and carefully mark each
wire at the holes in the servo arm. This is the neutral position
mark.
4) Measure 3/16” from the neutral position mark, towards the
unthreaded end of the wire, and make another mark. Now make
a third mark 1/4” away from the 3/16” mark.
5) Use a cutting pliers to cut the wires at the 1/4” mark. Put a “Z-
BEND” in the end of each wire, using the remaining marks as your
guides.
6) Unclip the R/C Links from the torque rods so that you can insert
the Z-BENDS into the holes in the servo arm.
After they are
installed, clip the R/C Links back on the torque rods. NOTE: You
will probably have to drill out the holes in the servo arm a little bit
to allow the Z-BENDS to go in.
7) Re-adjust the overall length of the aileron pushrods by
screwing the Nylon R/C Links further in or out, as needed to get
both ailerons into neutral position at the same time. Make sure the
aileron servo is neutral while doing this.
8) Plug the aileron servo into the receiver and test the operation
of the ailerons. If you sense any binding in the aileron movement,
