Volts and Amps Reports
The Volts and Amps reports are useful to better understand the flight characteristics and to identify potential issues with the aircraft. Path Color
The path color represents the Amperage used during the flight. It is common to see higher Amperage values while climbing up (red and purple colors), as well as while flying against the wind.
Consistent, non-green colors over a few flights may indicate the aircraft is working harder than it should, possibly due to a heavy load, bad motors, bad propellers, internal circuit problems, etc. Voltage Placemarks (letters)
Placemarks (letters) represent the location where notable voltage drops occurred. Voltage drops are normal and typically happen along with higher current (Amp) use. It is normal to see voltage drops when the load of the aircraft increases (Amps), typically seen when climbing up.
The lighter blue voltage drops (0.02v-0.1v) are normal and are seen on many flights. The darker blue voltage drops (more than 0.1v) happen more rarely and should be inspected more closely. Last, the darkest blue color indicates that the voltage dropped below 13.9v, which may indicate a risky flight condition. The low voltage indicator will show up on approximately 7% of all flights. Standard Range vs. Flight Specific Full Range
The range you select affects the flight path colors that are shown on the map.
The Standard Range uses standardized Amp values, determined based on all other flights, to show a constant color based on the Amps used. A certain value will always show the same color on all flights.
The Flight Specific Full Range will take each flight's lowest and highest Amp used, and adjust the colors to this specific flight range. This will cause all flights to show both the green and purple colors. This full range mode is very helpful with 'calm' flights (where only green or orange are shown), to allow the user to identify the portions of the flight that consumed the most energy.
Other Uses
Pilots who seek to master longer flights and better battery use can study the impact of their flying characteristics and observe how different maneuvers impact the battery use.
Return to Home (RTH) settings should be adjusted with the understanding of the energy required to climb up to the RTH altitude.
It is also recommended to view the KML files with Google Earth, to observe the different colors throughout the different altitudes.
