XP70 Instruction Manual
Purpose
This advisory outlines safety standards for operations of
model aircraft. We encourage voluntary compliance with
these standards.
Background
Attention has been drawn to the increase in model
aircraft operation. There is a need for added caution when
operating free flight and radio controlled craft in order
to avoid creating a noise nuisance or a potential hazard
to full-scale aircraft and persons and/or property on the
surface.
Operating Standards
Modelers generally are concerned with safety and exercise
good judgment when flying model aircraft. However, in
the interest of safer skies, we encourage operators of
radio controlled and free flight models to comply with the
following standards:
a. Exercise vigilance in locating full-scale aircraft (get
help if possible) so as not to create a collision hazard.
b. Select an operating site at sufficient distance from
populated areas so you do not create a noise problem
or a potential hazard.
c. Do not fly higher than 00 feet above the surface.
d. Always operate more than three miles from the
boundary of an airport unless you are given permission
to be closer by the appropriate air traffic control facility
in the case of an airport for which a control zone has
been designated or by the airport manager in the case
of other airports.
e. Do not hesitate to ask for assistance in complying with
these guidelines at the airport traffic control tower or
air route traffic control center nearest the site of your
proposed operation.

Daily Flight Checks
1. Check the battery voltage on both the transmitter and
the receiver battery packs. Do not fly below 9.0V on the
transmitter or below .7V on the receiver. To do so can
crash your aircraft.
NOTE
: The transmitter voltage reading has a load
to ensure the voltage reading is accurate. Use a
voltmeter that will place a load on the receiver pack to
ensure the voltage reading is accurate.
NOTE
: When checking the receiver batteries, ensure
that you have the polarities correct on your expanded
scale voltmeter.
. Check all hardware (linkages, screws, nuts, and bolts)
prior to each day’s flight. Be sure that binding does not
occur and that all parts are is properly secured.
. Ensure that all surfaces are moving in the proper
manner.
. Perform a ground range check before each day’s flying
session. The range check should be as follows:
• Do not extend the transmitter antenna at this time.
Turn the transmitter “on.”
• Turn the model “on.”
• Slowly walk away from the model while moving
the control surfaces. The aircraft should function
properly at a distance of 60–7 feet.
• For PCM Only: With the throttle fail-safe preset
to idle, bring the throttle slightly above idle. Walk
away until the throttle drops to idle. This will be the
distance of the range check.
. Prior to starting your aircraft, turn off your transmitter,
then turn it back on. Do this each time you start
your aircraft. If any critical switches are on without
your knowledge, the transmitter alarm will warn
you at this time.
6. Check that all trim levers are in the proper location.
7. All servo pigtails and switch harness plugs should
be secured in the receiver. Make sure that the switch
harness moves freely in both directions.
