Note: The following steps are for the use
of the prop saver on the park 250. If you
choose to use the Prop Adapter option of the
Park 250 then you should skip to page 11.
 1. Locate the motor mount and two 5mm plywood
motor mount spacers.
 2. Attach the motor mount to the firewall using the
two 5mm plywood spacers and two 2mm x 16mm
sheet metal screws. A #0 Phillips screwdriver will
be required to tighten the two screws. Note that
there are two different hole location/distances on
the firewall. The Park 250 will use the upper left
and the lower right when looking at the firewall
from the front of the airplane.
Always use threadlock on metal-to-metal fasteners
to prevent them from vibrating loose.
 3. The motor can now be attached to the mount.
Follow the directions provided with the motor and
use a 1.5mm flat blade screwdriver to secure the
motor to the mount.
 4. Connect the leads from the motor to the speed
control.
If you use all E-flite components in the
power system, you can connect the ESC and
motor wires by matching the colors and the
motor will spin in the correct direction.
 5. Secure the motor and speed control leads so
they do not interfere with the operation of the
motor.
