Key to the individual menu points:
- Chemistry: this is where you set the battery type. Three different types of
battery are available:
• Two-cell LiPo
• Two-cell LiIon
• Five-cell NiMH
• Two-cell LiFe
- Capacity: you can enter the nominal capacity of your batteries at this point.
- Output voltage: you can select the output voltage to 7.4V or 5.9V
CAUTION: if you intend to select the 7.4V output voltage, please ensure
before you make the change that all the consumer units connected to
the unit, i.e. all servos, receivers and gyros, are compatible with a 7.4V
supply. Information on this subject can be found in the instructions for
these components supplied by the manufacturers.
Compared with a direct, unregulated voltage of 8.4V, the advantage of a sta-
bilised 7.4V supply is that the voltage is always constant. This means that
the servos in your model always run at the same speed and with the same
torque, regardless of the manoeuvres you fly. For example, if you were to
operate the servos on the unregulated voltage of LiPo batteries, their run-
ning characteristics would alter as the freshly charged batteries steadily
discharged during the flight. Another major advantage of a regulated 7.4V
voltage is that it completely eliminates damaging voltage peaks (spikes);
this extends the useful life of the servos substantially.
