sides of the box (four marks total).
c) After you have all four slots marked, carefully align the front
face of the firewall to line up with the marks. Make sure you end
up with the firewall straight and square in the box. If it is not,
recheck your marks and adjust as necessary.
d) Tack glue the firewall in place. Recheck once more to make
sure that the front of the firewall is at the correct distance from the
back of the motor mount box. That distance plus the length of
your motor must equal 4-1/2”. When satisfied it is correct, glue
the firewall securely to the rest of the motor mount box.
❑ 29) Remove the X mount plate from the back of your motor and
center it on the firewall. Once you are sure it is properly located,
mark the mounting holes with a pencil. Remove the X mount and
drill out the mounting holes with a 7/32" dia. drill. Install four M4
Blind Nuts in the holes, on the back side of the firewall. Put a cou-
ple drops of glue on the flanges of the blind nuts to secure them
to the plywood. Be careful not to get glue in the threads.
❑ 30) Locate the piece of balsa triangle stock provided. Measure,
cut and install pieces of triangle stock to reinforce all the corner
joints inside the motor mount box.
❑ 31) Bolt the plywood motor mount box to the fuselage with M4
x 20mm Socket-Head Bolts and M4 Flat Metal Washers. Note
that two access holes have been cut in the bottom corners of the
firewall to allow access for your hex wrench.
❑ 32) If you have not already re-attached the X mount plate to the
back of your motor, do so now. Then use the M4 x 16mm Socket-
Head Mounting Bolts and Lock Washers to bolt your motor in
place on the plywood motor mount box.
❑ 33) Install your ESC
a) Solder appropriate battery connectors (not supplied) to the
battery leads of your ESC.
b) Most ESCs should fit underneath the battery tray behind the
firewall. If your ESC is too thick to slide in through the wing open-
ing, you may need to enlarge the forward hole in the battery tray
to let you install it from above. Secure the ESC in place with dou-
ble-sided tape or Velcro® tape (neither of these are provided).
c) Now route the ESC’s servo wire back to the receiver and
plug it in.
d) Connect the ESC's motor wires to the motor. Operate the
motor and check the direction of rotation. Always do this without
a propeller attached! If you need to reverse the rotation, refer to
the instructions that came with the motor and ESC.
SAFETY ISSUE: We strongly recommend the use of an “arming
switch” for your motor installation. With an arming switch you can
install your battery pack in the airplane and hook up the wires
without danger of the motor starting. The arming switch keeps
the electricity away from the motor until you “arm” it when you are
ready to takeoff. The most common arming switches are a simple
external plug that puts a break in the positive battery lead to the
motor, such as the Maxx Products Arming Switch shown below.
There are also arming switches built into some of the advanced
ESCs now on the market.
❑ 34) Two hook-&-loop (Velcro®) straps are provided to hold your
lipo battery pack in place inside the fuselage. Feed the straps
through the slots in one side of the plywood battery tray, and then
up through the other side, as shown in the next photo.
In addition to the two straps, it is a good idea to use hook-&-loop
tape (not furnished) on both the bottom of your battery pack and
