Range Testing (continued)
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, L - Frame losses 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 and if the same results occur,
move the offending receiver to a different location.
Tips for Getting the Most from your PowerSafe System
Flight Log
The optional Flight Log is highly recommended. The Flight Log can be used to
test the battery system using the built-in voltmeter and applying a load to the
servos/control surfaces. The voltage should never drop below the rated voltage
(5.9 volts) even under a heavy load.
When the system is first installed it is highly recommend that an advanced
range check be performed. (See Advanced Range Testing)
If any receiver is performing less than optimally (higher than normal fades) that
receiver should be repositioned and the advanced range test repeated until low
fades are recorded.
During first flights with sophisticated airplanes (significant conductive
materials onboard, many high-current draw servos, carbon construction,
etc.), it’s a good practice to keep your first flight in close then confirm the RF
link performance using the Flight Log to determine the performance of each
attached receiver. Extend the distance on subsequent flights and record the
Flight Log data confirming that all systems are performing properly.
Storing Your System
If the system will be stored for more than two weeks, it’s important that
the battery be disconnected from the PowerSafe Evolution. The PowerSafe
Evolution draws a small amount of current (less than 1ma) even when the
switch is turned off and the battery will drain and could become damaged if left
attached for an extended period. This is especially important when using LiPo
batteries as irreversible damage could occur to your batteries.
