View source for Motor Direction Check - Early BruGi Firmware

<i>August 2014</i><br>

'''NOTE: This process applies to all released BruGi firmware prior to 050_r202.'''<br><br>

The big problem with a motor direction check is that it is very difficult to actually see. Here is my method to "See" Motor Direction (re-written May 17, 2014):<br><br>

:1. Start with the system powered up
:2. Controller plugged into the USB and the GUI active with the waveform (trace) chart running
:3. Set the trace chart slider to the maximum (100) value
:4. Lift up the air-frame and while watching the trace chart, gently jerk the air-frame towards a forward pitch down (so the camera has to look up to stay level.

If the motor direction is correct you will see a spike in the orange trace line in the positive (up) direction. This is an indication of the direction of motor '''<i>reaction</i>'''. If the spike was not in the positive direction, either check or uncheck the motor reverse check-box <u>or</u> change any two motor wires where it connects to the board. Do the test again and you should now see the correct response. Repeat this for the roll axis using a left roll jerk motion.<br><br>
