Before beginning the assembly of your model you
should decide if you will be installing an electric or glow
power system. If you opt to install the electric system,
you will need to prepare the firewall at this time to
provide cooling for the speed control and battery, and
drill the holes for the blind nuts to mount the electric
motor.

Step 1
Use a drill and 7/32-inch (5.5mm) drill bit to drill the four
holes in the firewall for the blind nuts. The location has been
etched in the firewall.

Step 2
Use a hobby knife and rotary tool with a sanding drum to
remove the three areas on the firewall to allow cooling air to
pass into the fuselage for cooling.

Step 3
It may be necessary to remove the covering from the bottom
of the fuselage to allow cooling air to exit the fuselage when
using older batteries. If you are using the new Thunder
Power Generation 2 batteries or equivalent then the cooling
hole is not mandatory.
