a. Create a new spreadsheet
b. Go to File > Import > Upload. Drag your .CSV flight log file in, and Google Sheets
will import all the data
c. Sheets should automatically recognize this, but if it doesn’t, select Comma as the
separator character.
d. From here, you can view or edit any of your flight data
e. If you want to view it as a plot, select the data you want to view, then go to Insert
> Chart
f. Any data you view should also include the “Flight Time (sec)” column. Once the
chart is created, check the box beside “Use column B as labels”
4. If you don’t have a Google account(though they’re quite easy to create), there are
several account-free data viewers as well.

Troubleshooting
If you experience an error or anomaly when using the Signal R2 kit, you can likely diagnose it
with this table of problems and solutions. If you experience a problem not listed here, or none of
the solutions work, please contact BPS at [email protected].
Problems
Causes/solutions
Signal won’t turn on at all with the power connected
●
Check polarity of power input
●
Check voltage of power input - must be above
7v
●
Check for a possible short circuit on servo
outputs
●
Ensure all nearby metal objects make no
contact with exposed contacts on the PCB
Signal turns on, flashes the LEDs once, waits 2-3
seconds, then plays the 2-tone buzzer indication
●
Signal is missing an SD card, or it is not
connected well - remove and re-insert the SD
card
●
This can also be a file formatting error on the
SD card, sometimes it occurs with cards above
32gb in capacity. Try using a smaller card, or
reformatting it as FAT32.
Signal turns on, flashes all LEDs once, and immediately
plays the 2-tone buzzer indication
●
Signal cannot find the configuration file on the
SD card, or did not read it correctly. Remove
the SD card and delete the CONFIG.TXT.
Place it back in Signal and boot it up again
Signal boots up successfully, but does not enter
pad-idle mode, instead going straight to powered-flight
mode, with the red and blue LEDs flashing
●
The launch detection threshold is too low in
the configuration file. Anything less than 9.85
will likely cause this.
Near the end of startup, Signal halts the process and
●
Reboot the computer. Signal may have
