Tail Brace Wires
169.
Four 2-56 x10" Threaded Steel Rods are provided for the Tail Brace Wires. Cut
two of the rods to 8" long (including the threaded portion) for the Top Tail Brace
Wires. Cut the other two to 6-7/8" long for the Bottom Tail Brace Wires.
170.
Four 2-56 Steel R/C Links and four Solder Links are provided for the ends of the
Tail Brace Wires. Take all eight R/C Links and cut off the side that has the pin in
it. Builder’s Tip: A Dremel tool with an abrasive cut-off wheel works best for this.)
171.
Screw a 2-56 Hex Nut, followed by one of the modified 2-56 R/C Links on the
threaded end of each Tail Brace Wire. Solder the modified Solder Links onto the
other end of each Tail Brace Wire.
172.
Fit the wires to the model. Bend the ends of the links as needed to make them fit
flat against the model surface. Use 1-72 x1/2" Rd.Hd. Brass Bolts and Hex Nuts
to bolt the links to the stab and fin. Use two #2 x3/8" Sheet Metal Screws to hold
the lower end of the Bottom Tail Brace Wires to the plywood tailwheel mount.
173.
Adjust all the threaded links until the Tail Brace Wires are snug, but not pulling
the tail surfaces out of shape. Then, screw the hex nuts against the links to keep
them from coming loose.
Radio Installation - Ailerons
The aileron servos and extension chords were installed earlier, before covering
the wing. All that’s left is to hinge the ailerons to the wing and make the aileron
pushrods.
174.
Use four SIG Easy Hinges to hinge each aileron its wing panel. Use the same
procedures you did in the section "Attaching The Tail Surfaces" earlier. The
aileron hinges should be installed in the 3/32" balsa top sheeting of the wing and
aileron (see wing cross-section drawing on the plan).
175.
Screw a Nylon R/C Link onto the threaded end of a 2-56 x10" Threaded Steel
Rod. Screw it on until it’s halfway up the threads. Then, hook the Nylon R/C Link
up to the control horn in the aileron. Fasten a Solder Link to the aileron servo
arm. Center the aileron servo in neutral position. Tape the aileron itself to the
wing in neutral position. Now, hold the pushrod up against the Solder Link and
mark where the pushrod should be cut off. Cut off the pushrods, remove the
Solder Link from the servo arm, and solder the link to the end of the pushrod. Let
cool, then hook the pushrod back up and make final adjustment of the pushrod
length to achieve neutral position. Repeat steps to make the opposite aileron
pushrod.
Elevator
176.
Mount the elevator servo in the plywood servo tray in the fuselage.
177.
Locate the .130 x36" Nylon Elevator Pushrod Tube, two 2-56 x10" Threaded Steel Rods, a Solder Link, and a Nylon R/C
link.
178.
Cut one of the threaded rods to 1-3/4" long (including the threaded portion). Solder a Solder Link on the unthreaded end of
the wire. Screw the threaded end of the wire into the one end of the nylon tube. Try to get all of the threads screwed inside
the end of the tube. This will be the servo end of the elevator pushrod.
