receivers are operating optimally and that the installation (position of the receiv-
ers) 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.
1. Standing 30 paces away from the model, face the model with the transmitter in
your normal flying position.
2. Put your transmitter in range test mode. Range test mode reduces the power
output from the transmitter.
3. Have someone 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 fade or hold values. Perform this step for at least one minute.
5. Re-position any remote receivers as necessary.
6. Have your helper position the model in various orientations (nose up, nose
down, nose toward the Tx, nose away from the Tx, etc.) observe the telemetry
on your transmitter or while your helper watches the Flight Log noting any
correlation between the aircraft's orientation and frame losses. Do this for 1
minute. The timer on the transmitter can be used here. For giant-scale air-
craft, 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.
7. After one minute, a successful range check will have less than ten recorded
frame losses. Scrolling the Flight Log through the antenna fades (A, B, L, R) al-
lows 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.
8. A successful advanced test will yield the following:
H - 0 holds
F - less than 10 frame losses
A, B, R, L - Fades will typically be less than 100. It's 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.
