102 SPEKTRUM DX7 • GENERAL INFORMATION
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 4.7V on the receiver. To do so can crash your aircraft.
Note: When you check these batteries, ensure that you have the polarities correct on your
expanded scale voltmeter.
2. 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 properly secured.
3. Ensure that all surfaces are moving in the proper manner.
4. 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 60–75 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.
5. 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.
