Spinning props when disarmed

[Fletch]

Had a few problems with clean flight today ... Reflashed and had the same issue again ... And reflashed the  in the previous version and had the same issue....


I don';t use motor_stop I like all 4 props to spin at idle when its armed so I know for sure when its armed and dis-armed.

What I do is set the min and max throttles from the receiver tab in my case 991 to 2015 ... Then on the motors tab slide the master up until all 4 motors are idling nicely and set that as my min throttle signal. 

However ... When I power up the props start to spin (sometimes it takes an arm dis-arm cycle) throttle has no effect and they don';t change speed as you tip the quad...
When you arm they stop spinning.  Normal service appears to be resumed ... as you throttle up it flys and is nice and stable

Its bloody hard unplugging your battery with 4 props spinning!

I';ve got a really shonky video that kinda shows what I mean ... But was doing it one handed (yes I know I should have taken the props off)

I';ll upload it soon ....

How do you disarm? If it';s min throttle full left rudder your naze might not be getting the min throttle command due to you tinkering g with min throttle on tx. You could try changing arming to a switch

[Fletch]

It is ... The green LED is changing status with the ARM / DIS-ARM stick command

[xxpitt]

Maybe jyst turn motor stop on then till you find out what';s wrong. Better than losing some skin

i tried having props spinning when armed but it wasn';t for me. couple of crashes with the quad in the dirt with props still spinning for a few seconds was enough for me to go back to not spinning when armed.

Usually when i crash the props are already gone!

But the point of this is i managed to make the props spin while dis-armed!

When you update do a full flash erase. There maybe something left over from the previous config.
Can you post your settings for the following from the CLI

set mid_rc = 1520
set min_check = 1040
set max_check = 2000
set min_throttle = 18
set max_throttle = 2000
set min_command = 16

Ignore my values I';m using WiiESC in non standard setup  ::)

<thenickdude> mincommand is what is sent to the ESCs when disarmed
<thenickdude> when you calibrate the ESCs you calibrate against mincommand on the bottom end and then the ESCs treat that as their "idle" level and start spinning some 50us after that level
<add1ct3dd> set min throttle to 1100, and min command to 1000, then set your sticks from 1000 to 2000, and calibrate escs again

Cropped answer from IRC ... Basically my understanding was wrong

Beat me to it.

Glad you are sorted.
