battery leads of your ESC.
b) Decide where you want to install your ESC. We fastened
ours to the inside of the fuselage with common Velcro® tape (not
furnished).
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. Changing the
direction of rotation is normally a simple matter of swapping two
of the motor wires.
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.

32) The lipo battery pack will ride in a plywood battery box on
the floor of the fuselage, just in front of the servo mount. In this
step we will assemble and then install the battery box.
a) The battery box consists of (2) plywood sides and (1) ply-
wood top piece. Glue the top and sides together securely.
b) Take one of the supplied Velcro® straps and pull the short
"fuzzy" portion loose from the longer "hook" strap. Glue one end
of the short fuzzy strap on to one of the box sides, as shown in
the following photo. Glue the plain side to the wood, not the fuzzy
side. Epoxy glue works best for this step.
c) Cut the hook strap in half, and then glue one end of it to the
other box side. The hook side should be glued against the wood.
Epoxy glue works best for this step.
d) Trial fit the assembled battery box inside the fuselage. Note
that there are slots in the plywood fuselage floor to accept the
tabs on the bottom of the battery box. After you are familiar with
the fit of the battery box, glue it permenently to the to the plywood
floor and to the front of the servo mount.
In addition to the Velcro® strap at the front holding your lipo bat-
tery pack inside the box, it is also a good idea to use additional
Velcro® tape (not furnished) on both the bottom of your battery
pack and on the top surface of the plywood floor, to make sure
the battery pack will not move around during aerobatics.

33) For electric power we must let more air flow through the
firewall into the fuselage to cool the ESC and lipo battery pack.
Look closely at the bottom of the firewall, below the motor mount,
and you will see a rectangular shape that is partially cut through
the firewall. There are 4 tiny connecting tabs - one on top, bottom,
and each side - that hold it in place. With your thumb, push hard
on one side of the cutout and it should pop loose as shown in the
next photo. Use a knife if necessary. Discard the piece.
