rear of the fuse. If necessary, enlarge the slot with a small
razor saw.
❏
2. Use a hobby knife or a 5/32" [4mm] brass tube sharpened
on the end to cut a groove in the leading edge of the rudder
to accommodate the nylon tail gear bearing. Drill a 1/8"
[3.2mm] hole into the rudder for the “arm” portion of the tail
gear wire.
❏
3. Temporarily join both elevators to the stab with the
elevator joiner wire. Cut a half-round notch in the leading
edge of the rudder to accommodate the joiner wire. Test fit
the rudder to the fin and tail gear wire with three hinges.
Make adjustments where necessary. (For clarity, the
elevators are not present in the photo.)
❏
4. Remove the rudder, elevators and tail gear bearing
from the fuse. Take the elevator joiner wire out of the
elevators. Roughen the joiner wire with coarse sandpaper
so glue will adhere. Carefully apply a small dab of petroleum
jelly to the top and bottom of the tail gear bearing where the
tail gear wire goes through to keep glue from entering.
❏
5. Apply 30-minute epoxy to the joiner wire and to the
groove and in the holes in the elevators for the joiner wire.
Insert the joiner wire into the elevators (if you’ve had to
make any adjustments to the joiner wire to align the
elevators, be certain you’ve installed the joiner wire
correctly). Wipe away excess epoxy with a tissue dampened
with alcohol and immediately proceed to the next step.
❏
6. Apply 30-minute epoxy inside the slot in the fuselage
for the tail gear bearing and to the hinge of the tail gear
bearing. Install the tail gear bearing and wipe away excess
epoxy. Fit the elevators to the stab with the hinges.
❏
7. Apply epoxy in the hole in the rudder for the tail gear
wire. Also apply epoxy to the bare balsa in the notch for the
elevator joiner and to the groove for the tail gear bearing.
Wipe away residual epoxy. Fit the rudder to the fuse and tail
gear wire with the hinges.
❏
8. Permanently join the elevators and rudder with six
drops of thin CA on both sides of all the hinges.
Refer to this photo for the following three steps.
❏
1. Mount the engine mount to the firewall with four 6-32
x 3/4" [19mm] socket-head cap screws (SHCS), #6 lock
washers and #6 flat washers, but do not fully tighten the
bolts. Place the engine on the mount. If necessary, trim the
fuselage where required to accommodate the needle valve.
❏
2. Adjust the mount to fit the engine and place the back
plate of the spinner on the engine. Center the engine and
mount in the fuse, then tighten the screws to hold the mount
to the firewall. Position the engine to provide the desired
clearance between the back plate of the spinner and the
front of the fuselage–approximately 1/8" [3mm] is adequate.
Note: If your engine is too short to allow the drive washer to
extend 1/8" in front of the plywood spinner ring on the front
