Edf Fan Preparation & Installation - GREAT PLANES EP F-20 Tigershark ElectriFLy Instruction Manual

EDF FAN PREPARATION & INSTALLATION
This model uses the Great Planes ElectriFly Ammo 24-45-
3790 brushless in-runner motor (GPMG5185, included) and
the Silver Series SS-45 brushless ESC (GPMM1840, not
included)
❏
1. Use the included EDF fan instruction manual to assemble
and break-in the EDF fan unit. Do not install the rotor cone.
Use threadlocking compound on all screws. Before you glue
the EDF unit into your airplane, we recommend that you
check the fan and motor for proper operation. If there is a
problem it is much easier to take care of before the fan is
glued into the airframe. If you prefer, you can use double-
sided tape to hold your fan in place, but you will need to
recess the EDF channel in the fuse to accommodate the
thickness of the foam tape.
❏
2. Apply 30-minute epoxy or CA to the fan duct in the
recessed area where the EDF fan unit mounts. Mount the
fan in the model so that the ridges on the fan case drop
into the corresponding grooves in the fan duct. Mount the
motor so that the wires exit the motor and face the top of the
model. Allow the glue to fully cure. Note: During installation,
you may notice that the fan rotor's fl ange makes contact with
the inner duct cone. This is normal and helps improve fan
effi ciency. When you fi rst run the motor on the plane, the
fan will seat itself in the foam. If you feel that the fan is too
tight against the inner duct cone, you may trim the duct cone
using a hobby knife before installation. Trim a little at a time
and check the fi t.

3. Cut the 2" [51mm] piece of hook and loop fastener
material in half so that you have equal amounts of material
to fasten your ESC and receiver in place. Stick one piece on
the back side of your ESC. Turn the model over and route the
ESC motor leads through the upper channel inside the fuse
and out into the motor bay.
❏
4. Connect the supplied motor lead extensions to the
motor wires. Refer to the instructions that came with your
ESC to correctly arm and operate the motor. Check the
direction of motor operation and that air is blowing out of the
back side of the EDF unit. If the fan is rotating backwards,
swap the position of any two motor leads and test the fan
rotation again. Use 1/4" [6.4mm] diameter heat shrink tubing
(not supplied) to secure each connection. If heat shrink
tubing is not available, you may wrap the connectors with
electrical tape.
