Common Sense RC Servo Gauge

The Servo Gauge is an inflight present logger for your radio gear. You can use it to help detect servo or BEC issues in your system. It can likewise help you determine exactly what type of changing BEC you need for your system, or if you need one at all.

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

Max present that takes place throughout flight (Approximately 5A)
Max typical present throughout any 15 second interval (Approximately 5A)
Average present over entire flight (Approximately 5A)

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

The Servo Gauge installs inline in between your receiver and ESC. It displays the recorded 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 present recorded throughout the flight in .1A increments. That is, 12 flashes means a max current of 1.2A.

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

The "Max 15" reading reveals the highest typical drawn by the system over any 15 second period, and it is displayed by both lights blinking at the same time. It displays in .05A increments. For example, if they both flash 12 times, then 0.6A was drawn for 15 seconds, which means you need to look into updating to a changing BEC if you run 3s or greater packs.

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