Check allows you to evaluate the RF performance of each individual internal and
remote receiver and optimize the locations of
these receivers.
Advanced Range Testing Using a Flight Log
or Telemetry Module
1.Plug a flight log or the telemetry module
(optional) into the data port in the receiver
and turn on the system (transmitter and
receiver). If using the Telemetry module,
make sure it's bound to the receiver.
2.Advance the Flight Log until F- frame losses
are displayed, by pressing the button on the
flight log. Or advance the screen on the DX8
to show the flight log telemetry.
3.Have a helper hold your aircraft while he/she
observes the Flight Log data. 4.Standing 30
paces away from the model, face the model
with the transmitter in your normal flying
Position. Place the transmitter in the range
test screen and push and hold the trainer
button on top of the transmitter. This causes
reduced power output from the transmitter.
5.Have your helper position the model in
various orientations (nose up, nose down,
nose toward the transmitter, nose away from
the transmitter, etc.) while watching the
Flight Log, or the on screen telemetry noting
any correlation
between the aircraft's orientation and
Frame Losses. Do this for 1 minute. The
timer on the DX8 can be used here. For
giant-scale aircraft, tip the airplane up on its
nose and rotate it 360 degrees for one
minute, then record the data. Next, place
the airplane on its wheels and do a second
test, rotating the aircraft in all directions for
one minute.
6.After one minute, release the trainer switch. A
successful range check will have recorded
zero frame losses. Scroll the Flight Log
through the Antenna fades to evaluate the
performance of each receiver. Antenna
fades should be relatively uniform. If a
specific antenna is experiencing a high
degree of fades, then that antenna should
be moved to a different location.
7.A successful Advanced test will yield the
following: H- 0 holds F- 0 frame losses
A, B, R, L- Antenna fades will typically be
less than 100. It's important to compare the
relative antenna fades. If a particular
receiver has significantly higher antenna
fades (2 to 3X), then the test should be
redone. If the same results occur, move the
offending receiver to a different location.
