I would agree with you, if there where no signs of arming. But this is not the case. We have a green LED that shows you the state of arming. Furthermore you GCS is TALKING to you. If this is not enough, you can read out the mavlink messages and add some extra LEDS or a beeper (with mav2hott).

BTW, I had some experiance with accidentially rotating props. It took 12 stiches to get my forearm back in shape. And it was just a sailplane with 0.5kW, throttle @ maybe 25%. I do not want to imagine what would have happend with my 4kW Mustang or the 4.2kW TRex 700.

Using it like that you need the throttle hold to arm and after arming you switch the throttle hold of and the motors start spinning.
Way better because then you know what you are doing. That is the way every helicopter is armed since way back


This method is not totaly correct because in this case copter are in active phase of steering [sorry for my eng]
This mean when you arm with stick you have to make one more gesture to switch, or if you switch before it will couse yowing moment. And more, if multi placed on start not stright leveling it will begin to leveling with motors.

When armed it only have to speen on minimum rpm whithout active levelig or steering.

The LED totaly invisible during daylight, and less visible under gps skirt.

Speening is distinctly visible and play warning for bistanders, especialy for unpredictable children and animals.

You fly in the wrong spot if this is the case.

Fly safe

Didnt you fly in vicinity of people never?

Anyway it would good and responsible decision from programmers to make this feature for unresposible pilots.

This is always a controversial topic, and people have definite opinions on which way it should work. Since there are valid points to each position, the only way to satisfy everyone is to make it an option to spin or not when armed.

I personally want the motors spinning when armed, and I consider it a significant safety feature. The LED is only visible from a certain angle, so you have to make a special effort to look at it. It's absolutely certain that spinning props will be a more obvious sign than a solid vs blinking LED that you have to make an effort to look for.

FWIW, I've approached the AQ with it still armed, but I have enough previous scars to remind me to look for the light. The problem I have is that most FCs don't require you to hold the disarm position quite as long as the AQ does, so out of habit, I tend to not hold it long enough to actually disarm the AQ. I'm retraining myself now, but this is how accidents happen, and it would be much more obvious if the props were spinning.

I would definitely like to see this as an option.

Cheers,
Rusty

I agree that an option to have the props spin like the MK would be very good.

Another great safety feature is to have the board disarm after 30 seconds with no Tx inputs. Getting distracted and forgetting the AQ copter is armed is a very real danger.

Good idea
I am supportive for an option "spin @ arm" and for auto-disarm after a certain time with not taking of.

For instance Wookong disarm in 3 sec if no throttle input.

I too would like to see the motors spin on arming, simply because that's what im used to with my three other controllers. As it's a very personal thing, an optional setting would be great.
