3. Pick the triangle stock reinforcements with a hobby
blade and use medium CA to glue them into the mount box
around the inside of the front and back mount surfaces.
4. Drill 1/16" [1.6mm] pilot holes through the "O" marks in
the fi rewall, then enlarge the holes with a 5/32" [4mm] drill.
Insert 6-32 blind nuts into the back of the holes.
Refer to this photo while mounting the motor and ESC
in the steps that follow.
5. Mount the motor mount box to the fi rewall with four
6-32 x 3/4" Phillips screws and #6 lock washers and fl at
washers and threadlocker.
6. Assemble the "X" mount and the propeller adapter shaft
to your motor and mount the motor to the motor mount box
with four 4-40 x 1/2" Phillips screws and #4 lock washers and
fl at washers and threadlocker—notice that the motor wires
are positioned on the side of the mount box for a smooth
connection to the ESC.
7. Connect your ESC to the motor and mount the ESC to
the bottom of the motor mount box—for the Castle Creations
Edge Lite 75 ESC we soldered the female bullet connectors
that came with the motor to the three motor wires (protected
with 3/16" heat shrink tubing) and a Star connector to the
battery wires, then mounted the ESC to the box with a piece
of foam rubber and nylon ties.
8. Power up the ESC and use the transmitter to run the
motor to make sure it turns the correct direction. If the motor
turns the wrong way swap any two of the three motor wires.
9. Cut the two included 1/4" x 1/4" [6.5 x 6.5 mm] balsa
sticks to a length of 1-7/8" [48mm], then glue them across
the back of the fi rewall so the screws don't puncture the LiPo
battery in the event of a crash.
10. Attach the rougher, "hook" side of the included
adhesive-back hook-and-loop strip to the battery mount
plate and the other, softer "loop" side to your battery.
11. Make two 9" [230mm] battery straps by cutting two
6" [150mm] pieces from the rougher, "hook" side of the
included hook-and-loop material and two 6" [150mm] pieces
from the softer, loop side. Join the halves together with a 3"
[80mm] overlap.
