[SOLVED] Full throttle at any throttle given

Okay clear now, I see you followed the instructions to do manual programming mode when the automatic mode does not work.

But interesting that it works during the ESC calibration mode. Then it is just like the APM parameters are not being saved into the ESCs.

From the APM side you can double-check the calibration is saved by looking for changes in the RC3_MIN and RC3_MAX variables (like Navio without rc - #6 by netxingnet).

From the ESC side, a good ESC programming tool like RapidFlash will allow you to check them easily, and it could always be some kind of bug/incompatibility in your current firmware version so updating that could help:

Looks like the STOP_RC_PULS, FULL_RC_PULS, MIN_RC_PULS and MAX_RC_PULS are involved here.

If the ESC and APM calibration parameters both look good, then it could be a bug in the automatic throttle center feature of APM and you could look at those parameters. There are also a load of other throttle “feature” parameters, so resetting all parameters to default then going through initial setup could also help, especially if you played around with beta APM and Ground Control versions during your testing.

I guess the sign of an ESC problem would be if some ESCs still start at different times, and if the range/control logic (APM) is the only problem they should all start/stop/max at the same time after calibration.
