Range Testing

Before each flying session, and especially with a new model, it's important to
perform a range check. All Spektrum aircraft transmitters incorporate a range
testing system, which reduces the output power to allow a range check.
1. With the model resting on the ground, stand approximately 100 feet (30
meters) away from the model.
2. Face the model with the transmitter in your normal flying position and put
your transmitter into range test mode.
3. You should have total control of the model in range test mode at 100 feet.
4. If control issues exist, call Horizon Product Support for further assistance.
Advanced Range Testing
The Standard Range Testing procedure is recommended for most sport aircraft.
For sophisticated aircraft that contain significant amounts of conductive materi-
als (e.g. turbine powered jets, scale aircraft with matalized finishes, aircraft with
carbon fuselages, etc.), the following advanced range check will confirm that
all receivers in the system are operating optimally as installed. This advanced
range check allows the RF performance of each receiver to be evaluated
independantly. A telemetry equipped Spektrum Transmitter is required for the
advanced range test.
1. Stand approximately 100 feet away from the model.
2. Face the model with the transmitter in your normal flying position and put
your transmitter into range test mode.
3. Have a helper position the model in various orientations (nose up, nose
down, nose toward the transmitter, nose away from the transmitter, etc.).
4. Observe the telemetry on your transmitter. Note any orientations that cause
higher fades or frame loss values. Perform this step for at least one minute.
5. Re-position any antennas related to higher fades as necessary.
6. Re-test to verify satisfactory results.
7. Repeat as neccesary.
After one minute, advanced testing should yield:
H − 0 holds
F – less than 10 frame losses
A, B, L – Fades will typically be less than 100. It is important to compare the
relative frame losses. If a particular receiver has a significantly higher frame
loss value (2 to 3X) then the test should be redone. If the same results occur,
move the offending receiver to a different location.
TIP: Use the fade values for A to investigate the telemetry link performance.
