looking at the aileron at a shallow angle. If you cannot see it, the 
plate is approximately 1-5/8" [41mm] wide and will be inline with 
the servo arm. Use a T-pin to lightly puncture the covering to be 
sure you are over the plywood plate.

❏ ❏ 

7. Place a heavy duty nylon control horn on the aileron, 

positioning it as shown in the sketch inline with the outer hole 
of the servo arm. Mark the location for the screw holes. Drill 
through the marks you made with a 3/32" [2.4mm] drill bit. (Be 
sure you are drilling into the plywood plate mounted in the 
bottom of the aileron. Drill through the plate only. Do not drill 
all the way through the aileron!). Using a #4 x 5/8" [16mm] 
sheet metal screw, install and then remove a screw into each 
of the holes. Harden the holes with thin CA. Install the control 
horn with four #4 x 5/8" [16mm] sheet metal screws.

❏ ❏ 

8. Locate a .095" x 6" [2.4mm x 152mm] pushrod wire 

threaded on one end. Screw a 4-40 nut, a silicone clevis 
retainer and a threaded metal clevis onto the threaded end 
of the wire 20 turns. Tighten the nut against the clevis using 
threadlocking compound and then install the clevis on the 
outer hole of the aileron control horn.

❏ ❏ 

9. Be sure the aileron servo is centered and the servo 

arm is parallel to the hinge line. Install a 4-40 metal solder 
clevis onto the outer hole in the servo arm. Center the 
servo arm parallel with the aileron hinge line and center the 
aileron. Using the solder clevis as a guide, mark where to cut 
the pushrod wire. Remove the pushrod and clevis from the 
control horn and the solder clevis from the servo arm. Install 
another silicone clevis retainer onto the wire and solder the 
clevis to the pushrod using the “Expert Tip” that follows.

HOW TO  SOLDER THE  CLEVIS

TO THE  PUSHROD

1.  

Where the pushrod will make contact with the solder 
clevis, roughen the wire with 220-grit sandpaper.

2.  

Use denatured alcohol to remove any oil residue from 
the pushrod wire. 

 

 Note: Soldering should be done with silver solder, not 
an electrical solder. 

3.  

Apply a couple of drops of fl ux to the wire. Slide the 
solder clevis onto the wire. Using a small torch or 
soldering iron heat the wire, allowing the heated wire to 
heat the solder clevis. Apply a small amount of solder to 
the joint. When the wire and the clevis are hot enough 
the solder will fl ow into the joint. Avoid using too much 
solder, causing solder to fl ow out of the joint and clump. 
Use just enough solder to make a good joint. Allow the 
wire and clevis to cool.

4.  

Put a couple of drops of oil onto a rag and wipe the joint. 
This will prevent rust from forming on the joint.

❏ ❏ 

10. Install the pushrod and clevises to the outer hole in 

the servo arm and the outer hole in the control horn. Adjust the 
linkage until the aileron and the servo arm are both centered. 
Then, tighten the nut against the clevis with threadlocking 
compound. Slide the two silicone clevis retainers to the end 
of each clevis.

❏ 

11. Repeat these steps for the right wing panel.

Join the Wing Panels

❏ 

1. Trim the covering from the servo lead cutouts in the 

top of the wing panels. Feed the aileron servo leads through
the cutouts. Taping the leads to the top of the wing will keep 
them out of the way when joining the wing panels.

❏ 

2. Glue the 5/16" x 1-1/8" [8mm x 28mm] anti-rotation 

pin halfway into one of the wing panels as shown.
