Now that you have modified the hardware and/or firmware for the ELEV-8 v3, it is necessary to test its functionality to make sure it is safe to fly. Yes, do this every time you made hardware and/or firmware modifications!
DO NOT SKIP THIS PROCEDURE! Flying with untested firmware is dangerous and can cause severe injury or property damage or loss.
If you have not done so already, REMOVE YOUR PROPELLERS before proceeding!
If your ELEV-8 v3 fails to pass any of the steps below, STOP - disconnect the ELEV-8 v3's battery and return to prior steps to begin troubleshooting the problem.
Pay close attention to the RGB LED on the Flight Controller. During this process, it should continue to flash/alternate colors. Except during power-up, arming and disarming, if the LED stops flashing, there is a problem with your code and it is not safe to fly.
The Propeller microcontroller on the Flight Controller has a system clock that takes approximately 53 seconds to roll back over to zero and start again. Testing for 90 seconds ensures that the rollover will not cause a lock-up.
If your ELEV-8 v3 passed all of the above tests, it should be safe to re-install the propeller blades when you are ready to fly.
For your first flight with modified firware and hardware, follow all safety precautions.
Fly gently, close to the ground, and away from any people, objects, or structures until you are confident that your ELEV-8 v3 is performing normally.
