NOTE: When handling the motor and switch harness,
try to avoid bending the wires near the soldered con-
nections. If handled carelessly, these joints can be bro-
ken.
The following instructions are for installing the Turbo
550 motor. If using another motor, you may need to
modify the installation according to the motor manu-
facturer’s instructions.
IF USING A 2-CHANNEL INSTALLATION, PRO-
CEED TO STEP 4 and return to the fuselage side
view on the plan for switch location..
1. ‡ For a 3-channel installation, remove the lock
washer and nut from the top of the switch and
insert the ply mounting plate, as shown.
2. ‡ Locate switch mount just forward of former “B”
and about 1/2” below the top edge of the fuse
side. Refer to the top and side views on the
plan.
NOTE: The motor switch body must be turned, so the
switching action aligns with the pushrod from the motor
servo.
‡ When satisfied with the position, glue the
switch mount to the fuse side and former “B”.
4. ‡ Insert the motor through from the rear of
Former “A”, so that the motor front protrudes
about 1-3/4” out from the front of the fuse. Hold
the motor in its mount, using rubber bands.
For 2-channel only, drill or cut a 1/4” dia. hole
through the fuse side and mount the switch.
5. ‡ Using a scissors, carefully remove excess
plastic from the base of the cowl.
‡ Using a sharp hobby knife, rather than the scis-
sors, cut motor and vent holes. Do not try to
“force” the knife, since it could slip and damage
either the part or you. Instead, make a series
of light cuts, each a little deeper than the last.
6. ‡ Referring to the fuse side view on the plan for
the location of the screws, mark the location of
the screws and drill four 1/16” holes through
the cowl.
‡ Set the canopy in place on the fuse and then
position the cowl over the fuse front and the
canopy.
‡ When satisfied with the fit, screw the cowl in
place.
6. ‡ Thread a #4 socket set screw in the prop
mount and turn a few times.
‡ Open the spinner supplied by carefully insert-
ing a small screwdriver straight into each of the
slots. DO NOT TWIST! JUST PRY OPEN.
NOTE: Carefully read the instructions included with
your spinner. Rehydrating of the plastic will
make it easier to open and close the spinner .
‡ When the spinner backplate has been
removed, place it on the propeller mount.

3. ‡ Using a 7/64” drill, enlarge the nylon bracket to
fit snugly on the switch. You may need a mod-
eling knife to make the hole slightly larger than
7/64”.
‡ With the bracket flange parllel to the switching
action, glue the bracket to the switch.
