STEP 1: INSTALLINg THE ELEvATOR AND RUDDER SERvOS
❑ Install the rubber grommets and brass collets onto both your elevator and rudder servos, making sure to install the collets with the
flanges toward the bottom of the servos.
STEP 2: ASSEMBLINg THE ELEvATOR PUSHROD
IMPORTANT The elevator pushrod is assembled slightly differently than what you might be accustomed to. Because of the
narrow diameter of the hardwood dowel, we've elected to drill two staggered mounting holes for the two threaded pushrod wires.
This will allow a more secure hold-fast for the two threaded pushrod wires. Because the two mounting holes are staggered, you'll
also need to remember that when you make the 90º bend in each threaded pushrod wire, that you make one threaded pushrod
wire shorter than the other one so that they both line up evenly when installed.
❑ Cut one hardwood dowel to a length on 9-1/4" (235mm).
1" (25mm)
YOU'LL NEED THE FOLLOWINg PARTS FROM THE KIT:
YOU'LL NEED THE FOLLOWINg TOOLS AND SUPPLIES:
❑ Install the elevator and rudder servos into the two rear-most servo
mounting holes in the plywood servo tray, making sure to drill 1/16" (1.6mm)
diameter pilot holes for the mounting screws.
IMPORTANT When installed, both servo output shafts must be toward
the back of the fuselage.
❑ Drill one 5/64" (2mm) diameter hole through the center of the hardwood
dowel, 1" (25mm) in from one end.
❑ Drill two 5/64" (2mm) diameter holes through the center of the opposite
end of the hardwood dowel. Position one hole 1" (25mm) in from the end
and the second hole 1-1/8" (28mm) in from the end.
1" (25mm)
IMPORTANT Drill the two holes perpendicular to the first hole that you
drilled.
1-1/8" (28mm)
❑ Cut a shallow groove from the base of each of the three holes to the ends
of the dowel. The grooves should be just large enough for the pushrod wires
to fit firmly into when they are installed.
