While the above Standard Range Testing procedure is recommended
for most sport aircraft, for sophisticated aircraft that contain significant
amounts of conductive materials (i.e. turbine powered jets, some types of
scale aircraft, aircraft with carbon fuselages, etc.), the following advanced
range check will confirm that all internal and remote receivers are
operating optimally and that the installation (position of the receivers) is
optimized for the specific aircraft. This Advanced Range Check allows the
RF performance of each remote receiver to be evaluated and to optimize the
locations of each individual remote receiver.
Advanced Range Testing
1. Plug a Flight Log (optional) into the data port in the PowerSafe and turn
on the system (Tx and Rx).
2. Advance the Flight Log until frame losses are displayed by pressing the
button on the Flight Log.
3. Have a helper hold your aircraft while he observes the Flight Log data.
4. Standing 30 paces away from the model, face the model with the
transmitter in your normal flying position and depress and hold the bind
button on the back 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 Tx, nose away from the Tx, etc.) while
your helper watches the Flight Log noting any correlation between
the aircrafts orientation and frame losses. Do this for 1 minute. The
timer on the transmitter can be used here. For giant-scale aircraft it’s
recommended that the airplane be tipped up on its nose and rotated 360
degrees for one minute then the data recorded. 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 bind button. A successful range check
will have less that ten recorded frame losses. Scrolling the Flight
Log through the antenna fades (A, B, L, R) allows you 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- less than 10 frame losses
A, B, R, L- Frame losses will typically be less than 100. It’s
important to compare the relative frame losses and if a particular
receiver has a significantly higher frame loss value (2 to 3X)
then the test should be redone and if the same results occur,
move the offending receiver to a different location.
