How to get the Motors to start?

[axelnied]

I managed to upload the mix table to the AQ.
The ESC32s are set up with CL values in open-loop mode...
I am using T-Motors 2212.

I can arm the motors via stick (throttle down, yaw right) but the motors won't start.
Only if I move the stick up a little bit, the motors would start to run.
When I move throttle all the way back again the motors would stop.

What is the right procedure to get the motors to start when armed?
I was experimenting with the PWM_MIN_START in QGC, but without success.

Thats exactly how mine behaves. The motors will not start when armed only.

I would really prefer to have the motors spin (on low) when armed!...
On the MWii software there is an option to turn it on and off. I was experimenting with it with a bloody ending Never lean forward over your TX!!!

Maybe there is an option to set initial PWM higher. But I can not help here.

Since I cut my arm with a sailplane when opening the throttle with my "belly" while leaning foreward I always hold my left thumb on the thottle.

Menno,

That means, if you fly your AQ and pull the throttle stick all the way back, your motors stop midair (and will probably start rotating the opposite direction due to free fall)?

I see 2 different discussions here.
On one hand the "spinning idle on arm" signalizes "We're up and running" - I like that, too.

On the other hand you should avoid a free fall with zero throttle. Idle spinning motors won't do much to give the FC a chance to avoid a crash.
Below hover point it descends, below take off throttle point it falls, zero throttle makes it drop like a dead bird.

Unless we have a free fall detection with automatic emergency reaction we leave it up to the pilot's thumb.

Norbert,

Thanks for joining this conversation... Maybe I will change my question(s) to
Q1: How do I get the motors to spin on arm?
Q2: How do I avoid "free-fall" with zero throttle if motors stop at minimum throttle setting (stick back)?
Q3: How does your current setup behave?
