Common Sense RC Servo Gauge

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

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

Max existing that happens throughout flight (Up to 5A)
Max typical existing throughout any 15 second interval (Up to 5A)
Average existing over entire flight (Up to 5A)

Max current will inform you if you're risking a BEC shutdown due to overcurrent.
Max over 15 seconds will inform you if your BEC is likely to get too hot and shut down.
Average existing will inform you what does it cost? of the capability of the battery powering the receiver is being used.

The Servo Gauge installs inline between your receiver and ESC. It shows the taped information by blinking LEDs, then you can refer to the chart to go from number of blinks to number of amps.

The red LED blinks out the optimum existing taped throughout the flight in .1A increments. That is, 12 flashes suggests a max current of 1.2A.

The green LED blinks out the typical existing in .05A increments. 5 flashes would mean the typical existing drawn throughout the flight was .25A

The "Max 15" reading shows the highest typical drawn by the system over any 15 second period, and it is shown by both lights blinking at the same time. 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 switching BEC if you run Threes or higher packs.

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