Hi!
I was trying to autotune my low-budget S500 chinese-pixhawk quad yesterday…
Everything was going great, roll autotune finished and pitch was ongoing and suddenly my quad went down without any clue.
I was trying to analyze the flight log data using Dronee Plotter, and I see some GPS Glitch but I’m not sure if that was the real issue that put my quad on the ground.
Can you help me on diagnosing the real issue here?
Looks like thrust loss on Motor 3
Thanks!
How can you tell? Which parameter should I’ve been looking for?
And if you’re right, what should have happened? I have no clue… there was zero wind, open field without interference, no power issues…
Graph the RCout’s. When an outpout is commanded to max as it shows for Motor 3 it’s trying to compensate for a thrust loss. Could be a motor, ESC, broken prop, etc.
Ok, thanks for the answer.
I thought it was an ESC, but today I tried to start the quad again and all the motors turn. How can I diagnose a faulty ESC?
Check the solder joints. It’s all soldered right, no bullet connectors?
What ESC’s are they?
Just generic ESC’s, those with banana connectors:
As you asked, I just realized that I used a 5S battery, and those ESC’s and motors are 4S rated…
