Common Sense RC Servo Gauge

The Servo Gauge is an inflight current logger for your radio gear. You can use it to assist detect servo or BEC issues in your system. It can also help you identify exactly what kind of switching BEC you require for your system, or if you require one at all.

Servo Gauge is created to be owned from a receiver battery or a BEC and measures the following:

Max current that happens during flight (Approximately 5A)
Max average current during any 15 2nd interval (Approximately 5A)
Average current over entire flight (Approximately 5A)

Max current will tell you if you're risking a BEC shutdown due to overcurrent.
Max over 15 seconds will tell you if your BEC is most likely to overheat and shut down.
Average current will tell you just how much of the capacity of the battery powering the receiver is being used.

The Servo Gauge sets up inline between your receiver and ESC. It shows the tape-recorded information by blinking LEDs, then you can describe the chart to go from variety of blinks to variety of amps.

The red LED blinks out the maximum current tape-recorded during the flight in .1A increments. That is, 12 flashes means a max current of 1.2A.

The green LED blinks out the average current in .05A increments. 5 flashes would imply the average current drawn during the flight was .25A

The "Max 15" reading reveals the greatest average drawn by the system over any 15 2nd period, and it is displayed by both lights blinking all at once. It shows in .05A increments. For example, if they both flash 12 times, then 0.6A was drawn for 15 seconds, which means you should check out upgrading to a switching BEC if you run 3s or higher packs.

Servo Gauge will deal with receiver loads from 3.5V to 15V, along with 5V or 6V BECs.
