With Parallax GroundStation software now installed on your computer, you can use it calibrate the throttle range of your ESCs and check the spin direction of your motors before mounting your ESCs to the booms, as you will do in the this section's three steps.
This section will take approximately 20 to 60 minutes to complete, depending on skill level and equipment.
Before moving on, the ESCs (electronic speed controllers) will need to be calibrated. This process tells the ESCs the minimum and maximum throttle range sent from the flight controller to the ESCs. If this is not done before flight, your motors may not respond correctly – causing unstable or unpredictable flight.
This calibration process is done using the Throttle Calibration button and by disconnecting and reconnecting your flight battery in a specific manner: you will need to have a charged battery and be able to connect and disconnect it during this process. Again, make sure that your propellers have been removed.
The Parallax GroundStation application will visually indicate when to unplug or plug in your battery during this calibration process. Watch for screen indicators.
To hear what the series of beeps in instructions 4 and 5 should sound like during a successful calibration, download this .zip file containing a wav sound file for each instruction [3].
Now you will check that the motors are spinning in the desired direction. If any motors are spinning in the wrong direction, it is a simple matter of switching any two of the ESC outputs to fix the issue.
Warning! Propellers should not yet be installed on your ELEV-8 v3. If you have done so, remove them now before continuing.
If the motor spun in the correct direction (as indicated by the markings on your top chassis plate, shown below), skip to step 8. If it did not, follow steps 5-7.
If the Motor Did Not Spin in the Correct Direction:
With the motors all spinning the correct directions, you can now secure the ESCs so that they don't move during flight. By securing them to the booms, they won't get in the way of folding up your ELEV-8 for transport if you ever choose to do so.
