Install the Fan Unit
The fan unit is easy to install, but it takes a little fi nagling
to get it through the intake hole. It’s a good idea to test fi t
the fan without glue so you can make sure it fi ts properly.
Once permanently installed, the fan unit will not be possible
to remove. However, the motor may be removed by taking
off the fan rotor, unscrewing the motor mounting screws and
taking the motor out the back through the tail cone. Once
the motor is out of the tail cone, the motor wires can be
disconnected. If you can’t get a good enough grip with your
fi ngers to pull the fan rotor off the adapter, make a rotor
puller from an 8-1/2" [215mm] piece of 2-56 pushrod wire
by bending it as shown. Insert the short hooks on the ends
of the puller under the fan hub and pull.
ROTOR PULLER 1" [25mm]
3-1/2" [90mm]
1/4" [6mm]

1. With the fan unit on its side (so the wire cutout in
the housing fl ange will straddle the edge of the fuselage
opening), drop the rear, then the front of the unit down into
the fuselage.
❏
2. Rotate the fan unit until the motor wire cutout is centered
in the top of the fuselage just under the fi n. The motor wires
should also be in the top of the fuselage as shown.
❏
3. Guide the fan unit aft until the cone adapter mates with
the tail cone already in the fuselage and the front housing
fl ange is just aft of the opening. Note that the cone adapter
should key around the inside of the front of the tail cone.
❏
4. Now that you’ve confi rmed how the fan unit fi ts, remove
it from the fuselage. Apply a bead of 30-minute epoxy mixed
with microballoons fi ller (or just 30-minute epoxy) around
