Make sure your elevator servos are centered and mount your servo arms
straight down at 90 degrees from the fuselage thrust line.
Ensure your rudder servo is centered and mount your rudder servo arm.
Ensure your aileron servos are centered and mount your arms parallel to
the hinge line and
not parallel to the top of the servo.
Screw in your four metal pushrod ends, ¾’s into each horn for the
elevators and ailerons.
If you have not done so already, screw in the remaining metal pushrod
ends ¾’s into each 4/40-ball links and mount the ball links to your servo
arms.
Install the horizontal stabilizer/elevator assemblies at this time. Insert the ½ inch carbon fiber stab tube.
Slide each stabilizer half onto the tube. Make sure the anti-rotation pins are fully seated. Install four
4/40 bolts (two per side). Don’t forget the spring and flat washers.
Take some masking tape and tape the elevator counter balances to the stabilizers so that they are in a
center position.
For the wing, tape the ailerons to the wing in its center position.
Now we’re ready to assemble the carbon fiber push rods.
Again, make sure your servos and control surfaces are centered. Take
your ruler and measure the length of CF rod you will need to cut for each
control surface.
Cut the four rods needed to the proper length with a mask using care not to
breath any of the CF dust. Take masking tape and single wrap the area to
be cut. We recommend using a small hand saw while rotating the rod
until it falls away cleanly. A Dremel tool or similar will work, but it tends
spread more dust.
Remove the tape from the pushrods and test fit the pushrods and make
sure your surfaces are still centered with the servos in the centered
position.
Tip#7 You may use slow Rubber Toughened CA for the next step. We have
found this to be just as strong as JB weld without the long curing times. CA
accelerator will work well with this product. Be carefull not to get the CA on
you aircrafts covering. If using the CA, you may wish to assemble your
pushrods while removed from the plane.
If satisfied with the fit, mix the JB weld and apply a liberal amount into the metal pushrod ends. Insert
the CF rods and rotate them one turn to ensure they have been covered with the weld. Wipe off any
excess weld and secure the horn and the servo arm with a rubber band to hold the pushrods together.
Allow at least 24 hours for the JB weld to cure. After 24 hours, check push rods by attempting to pull
them apart by hand.
