21. Drill a hole through the bottom of the
fuselage and through the fuselage
doubler FD for the towhook mounting.
Measure the exact location for this hole
carefully from the plan, as the towhook
position is critical for achieving a good
launch of the sailplane. Install a 4-40
blind nut in the hole on the inside of the
fuselage.
22.
The fuselage is now ready for final sanding. Sand off all "Tee-Lock" stubsa and round the edges of the fuselage with a
sanding block. Start out with 150 grit sandpaper and switch to 220 grit sandpaper for the final sanding.
Servo And Pushrod Installation
23.
Drill the elevator and rudder pushrod exit holes in the fuselage sides as shown on
the plans. Use a 1/8" drill bit at first for a pilot hole and follow it up with a 3/16" drill
bit.
24.
Install the 3/16" o.d. outer nylon pushrod tubing for the rudder and elevator
pushrods into the fuselage by passing them through the previously drilled holes.
NOTE: Make sure that the outer pushrods extend out past the former F-3 for 3/4".
25.
Epoxy the outer pushrod tubing in place at the rear of the fuselage and at the
formers F-3 and F-4.
26.
Use a single-edge razor blade to trim the
outer pushrod tubing flush with the
outside of the fuselage sides.
27.
Die-cut 3/32" plywood servo rails (SR-1, SR-2, and SR-3) have been provided. Trim the servo rails if necessary to fit your
particular servos. Epoxy the rails in place in the fuselage between formers F-2 and F-3. Mount the servos to the rails in the
manner recommended by the radio manufacturer.
The rest of the pushrod installation will be done later during "Final Assembly", after the tail surfaces are mounted to the
fuselage.
BUILDER`S TIP
Although it's not shown on the plans
we recommend that you add scrap
pieces of 1/4"x5/16"x1" balsa
between the fuselage sides to
increase the gluing area for the
stabilizer.
