I found similar topic (Motor still spin after shut off) , but will ask for clarification here as well.
So, the issue is, that after putting throttle all the way down, motors stop spinning only after couple of seconds.
MOT_SPIN_ARM is set to 0 as well as MOT_SPIN_MIN is also set to 0.
Copter crashed and you need quickly show down the motors.
There are few possibilities:
- Disarm - 2+ seconds for proper stick movement and disarm delay.
- Motor emergency stop - 1+ second for reaching correct switch and use it.
- Just move throttle to 0 - <0.5 second, but it does not work :(.
I have cheap Chinese drone for training and on throttle down it stops spinning of the motors instantly.
Currently I worked around 3) using Taranis features:
On Throttle > 0 -> Motor Interlock ON via aux channel
On Throttle ~0 -> Motor Interlock OFF via aux channel
Having this, motors stop pretty quick, but I feel there is better way to achieve this, rather such hacks.
So, question is - is there a way (by tuning some parameter or so) to enable behavior of instant stopping of the motors?
