Common Sense RC Servo Gauge

The Servo Gauge is an inflight present logger for your radio gear. You can use it to assist diagnose servo or BEC problems in your system. It can also assist you identify exactly what type of switching BEC you need for your system, or if you need one at all.

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

Max present that occurs throughout flight (As much as 5A)
Max average present throughout any 15 2nd interval (As much as 5A)
Average present over whole flight (As much as 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 get too hot and shut down.
Average present will tell you 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 taped details 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 present taped throughout the flight in .1A increments. That is, 12 flashes suggests a max current of 1.2A.

The green LED blinks out the average present in .05A increments. 5 flashes would indicate the average present drawn throughout the flight was .25A

The "Max 15" reading shows the highest average drawn by the system over any 15 2nd duration, and it is shown 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 suggests you ought to look into upgrading to a changing BEC if you run Threes or higher packs.

Servo Gauge will deal with receiver packs from 3.5V to 15V, as well as 5V or 6V BECs.
