h)

A long stick of balsa Tri-Stock is provided to reinforce the motor

mount. Measure, cut, and glue pieces of triangle stock in all the
corner joints on the face of the mount box using medium CA.

i)

If you have not already re-attached the X mount plate to the

             back of your motor, do so now. Then use (4) M4 x 16mm Socket
             Head Mounting Bolts and Lock Washers to  bolt  your  motor  in
             place on the plywood motor mount box.

❑

14) Install your Speed Control (ESC) and Battery

a)

Solder appropriate battery connectors (not supplied) to the

battery leads of your ESC.

b)

Decide on a good location for the ESC in the nose of the

            airplane. The most likely  location  is  on one  side  of  the  motor
            mount    box.   Mount   it  to  the  airframe’s  structure   using    a
            method   of  your  choice – like   double-sided    tape   or   Velcro®
            (neither of these  are provided). In  this case, the Castle Phoenix
            Edge  75Amp  ESC  fit  perfectly  on  the  side  of  the  motor  box,
            and was attached   with shortened servo   screws,  and a   Zip
            Tie   (Not furnished).)

c)

Now route the ESC’s servo wire into the fuselage, and temporarily

connect it to the receiver.

d)

Connect the ESC's motor wires to the motor. Operate the motor
and check the direction of rotation. NEVER DO THIS WITH A

PROPELLER INSTALLED! 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 y our battery pac k in t he 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 A rming S witch (SIG Part# M XACC6972)

shown below. There are also arming switches built into some of

the advanced ESCs now on the market.

e) The battery will sit inside the motor mount box. Slip one or both

    of the Velcro® straps through the slots in the motor mount box
    and attach the hook side to the loop side. It is also a  good idea
    to add some  adhesive-backed  Velcro®  (Not  Furnished)  to  the
    floor of the mount box and to your  LiPo battery.  This  will  help
    prevent the battery from shifting during flight.
