If you have purchased the version of the XPD-8 ARF that
includes the HyperFlow

EDF unit, a 370 BB brushed motor

is also included so you will not need to purchase a motor. If
you purchased the XPD-8 ARF without the EDF unit and
motor, or if you plan to install an optional brushless motor,
consult the Hyperflow EDF manual. This manual is available
at our web site at www.greatplanes.com, and contains
performance charts and motor requirement data that will be
useful in choosing a brushless motor.

An ESC (Electronic Speed Control) with BEC (Battery
Eliminator Circuitry) is required. The BEC allows both the
motor and the radio system to be powered by the same battery
(thus eliminating the on-board receiver battery). The Great
Planes ElectriFly C-25 Mini Brushed ESC (GPMM2025) is
recommended for use with the 370 BB brushed motor.

If using a brushless motor, be sure to choose an ESC
designed specifically for brushless motors and one that is
capable of handling the current draw of your application.

The only adhesive required to build the XPD-8 ARF is
6-minute epoxy or foam-safe CA glue. Either one works well.

When you see the term 

test fit in the instructions, it

means that you should first position the part on the
assembly without using any glue, then slightly modify
or 

custom fit the part as necessary for the best fit.

Whenever the term 

glue is written you should rely upon

your experience to decide what type of glue to use.
When a specific type of adhesive works best for that
step, the instructions will make a recommendation.

Whenever just 

epoxy is specified you may use either

30-minute (or 45-minute) epoxy or 6-minute epoxy.
When 30-minute epoxy is specified it is highly
recommended that you use only 30-minute (or
45-minute) epoxy, because you will need the working
time and/or the additional strength.

Photos and sketches are placed before the step they
refer to. Frequently you can study photos in following
steps to get another view of the same parts.
