pulsext wrote: I had my elevator servo fail on me today (thankfully after my four flights!) and after very careful inspection it was clear that the pot has failed. There is mostly no movement with stick inputs and when there is, it is intermittent and only working with the servo held in different angles. My question is what would cause the pot to fail like this? I obviously do not want to just replace the servo only to have it fail in the same manner! Could it be the higher voltage of the 6.6v life pack? Or could it be that there was too much load on the servo? It is worth mentioning that it is a new servo with less than 10 flights on it. Any advice will be gladly appreciated!
For all analogue servos, including HS-311, suggest best compromise is to run a
switchmode regulator at 5vThe higher the voltage, the higher the servo speed and torque and heat generated which also results in a much faster burn out
of components being reason many new digitals have a partial or all alloy case.
Without viewing the servo and installation, it is difficult for readers to get a full understanding of where any problem originated.
