Setting RC_SPEED > 490

If I set the RC_SPEED to e.g. 600 or 620 Hz and set the motors to max speed, the ESCs seem to restart (beep) and the motors switch off for a second. I tested with HobbyWing X-Rotor ESCs.

I have to add that with Navio+ it was working to set the RC_SPEED higher than 490. With Navio2 it seems problematic.

The maximum speed for the RC_SPEED is 490Hz… This is a limitation of Ardupilot as well as the Navio 2 Co-processor.


Then this is definitely a better not touch variable.
