Install The Radio System - GREAT PLANES Little Toni ARF Instruction Manual

10. Make any adjustment needed to align the paint lines on
the cowl with the fuselage. At each of the reference lines you
have drawn on the fuselage, measure from the fuselage back to
the cowl 1-1/2" [38mm]. Mark that location on the cowl.
11. Drill a 3/32" [2.4mm] hole through the cowl and fuselage
mounting blocks at one of the four locations. Temporarily screw
a #4 x 3/8" [9mm] sheet metal screw and a #4 flat washer into
the cowl and fuselage. Drill a hole at another location. Install
another screw and washer. Do this for all four mounting blocks.
12. Remove the cowl. Apply a couple of drops of thin CA
to the holes to harden the threads. After the glue has cured,
install the cowl with the #4 x 3/8" [9mm] sheet metal screws
and #4 flat washers.
13. Using a technique similar to the way you located and
cut the cowl for the engine cylinder head, make any
additional cut outs needed in the cowl for the needle valve,
muffler, glow plug, etc.

1. Locate three .074" x 36" [.074" x 914mm] pushrod
wires threaded on one end. Screw a nylon clevis onto the
threaded end of the wires 20 full turns. Install a silicone
clevis keeper onto the clevises.
2. Slide two of the wires with clevises attached into the
openings closest to the back of the fuselage on both sides
of the fuselage.
3. Connect a nylon control horn onto each of the two
clevises. Position the control horn on the elevators,
positioning it the same way as you did with the ailerons.
Mark the location for the screw holes. Drill through the
marks you made with a 1/16" [1.6mm] drill bit, drilling
through the elevator. Secure the control horn to the elevator
with two 2-56 x 5/8" [16mm] machine screws and the nylon
mounting plate.
4. Connect the third rod into the remaining opening in the
fuselage. Connect the control horn to the clevis and attach
the control horn to the rudder in the same way you installed
them to the elevators.
