string tied to it - this is the other end of the string in the aileron
servo bay. Leave the string in place for now.
❑
3) From the kit contents, locate the bag containing the two
factory covered aileron servo hatches, the aileron servo mounting
blocks, and the mounting screw hardware. The aileron servos are
now mounted to the factory covered plywood servo hatch covers -
note that there is a left and a right hatch cover, made to fit the left
and right wing panel hatch openings.
Begin by installing the
rubber grommets and brass eyelets (supplied with your radio
system), into both aileron servos. Use epoxy or slow CA glue to
mount the 3/8" x 3/4" sq. hardwood servo mounting blocks to the
inside surface of the hatch cover, using the servo itself for spacing.
First, position the servo with its output arm directly over the center
of the hatch's clearance slot and centered in the middle of the "1/2
slot" cut-out. Allow the glue to set. With the servo mounting blocks
now glued in place, remove the servo. Assemble the remaining
servo hatch cover and servo mounting blocks in the same manner.
❑
4) From the screws included in the aileron servo hatch bag,
select the four smaller #2 x 8mm PWA mounting block screws.
These screws are used to mechanically secure each servo
mounting block to the servo hatch cover. Use a ruler to find the
approximate center of each block and mark the location onto the
covered side of the aileron servo hatch. With a 1/16" dia. bit, drill
two holes - about 1/4" deep - through each servo hatch and into
the mounting block, at the marks just made. Install and tighten the
four screws in place through both servo hatch covers.
Use the servo mounting screws provided with your radio system to
secure both aileron servos in place to the mounting blocks on each
aileron servo hatch. To avoid possibly splitting the mounting blocks
with the screws, first pre-drill the holes with an under-size drill bit.
❑
5) The servo hatch covers, with the servos in place, are now
prepared for mounting into each wing panel. Carefully insert the
servo cable into the servo bay and position the hatch cover into the
recess (if the scrap piece of wood with the retrieval string tied to it
is in the way, break the piece of wood away and lay it in the servo
bay for now). Use small pieces of tape to hold the hatch in position
on the wing panel. Use a 5/64" dia. bit to drill four holes in each
corner of the servo hatch, through the hatch and the corner
plywood mounting gussets, built into the wing. Be careful when
doing this, not to run the drill bit through the top of the wing!
Remove the servo hatch from the wing.
Re-drill the four corner holes in the servo hatch, using a 1/8" dia.
bit to allow clearance for the #3 screws. The aileron hatch covers
are now complete and ready for mounting.
❑
6) At this point, it is time to connect the two aileron servos to
the Y-harness and the receiver, in order to set and adjust their
center points. Slip the servo arms onto each servo and place them
together on your workbench, with the servo arms facing each
other.
This gives you a good visual reference.
Turn your
transmitter on and then the receiver. Re-position the servo arms
on the servo splines, getting them both as close to 90
O
as possible.
