Pilot RC Yak 54 - User Manual

1. Inventory the parts in your kit and familiarize
yourself with the assembly manual before start-
ing on this project. If this is your first aerobatic
model, get an experienced modeler from your
club to help you or call your local retailer.
2. Start working on the fuselage before the en-
gine is mounted. It is lighter and much easier to
handle on the workbench.
Rudder and tail wheel installation
1. Start with the Rudder before going to the
elevator since it will be easier to get to and
mount all the hardware.
2. Cut out the slots in the rudder to accept the G-
10 fiberglass dual rudder horns making sure they
are equal distance on both sides of the rudder to
prevent an off center throw. Apply 15 minute
epoxy to the horns making sure the holes are
filled and then slide the two keeper lock plates
in place at the same time. Wipe off any excess
epoxy with rubbing alcohol. Install the 4/40 ball
and swivel rod ends to keep the horns aligned
while the epoxy cures. Only snug up the bolts
and nylon insert nut so as not to crush the fiber-
glass horns. Make sure the push rod swivels are
mounted in the same width holes as the rudder
arm.
3. Trial fit the rudder hinges in place to make
sure it is free. You will glue this in later after
you get the tail wheel bracket mounted.
4. Draw a center line on the tail wheel mounting
block.
5. Tape the tail wheel bracket into place and
drill 3 holes the same size as the bracket holes.
6. Remove the access hatch in the rear.
