No, throttle is calculated as an average based on your climb_rate. You can fly around in Stablize and if you hover at least 10 seconds, it will auto-calibrate.

This is good to know.  Thanks

But my question revolves around where I set my throttle when the quad is at a high altitude where I take pictures,  since I can not see if it is holding steady or not.

So I should hover for this period of time, check the throttle position, then use this position for Alt_Hold at high altitudes?

(Loved the ABC report)

Jason,

I'm having problem with holding height with APM2 and 2.5.3

When I engage AH lets say at 1 meter, the quad rises to about 3 meter.

Could this, what you are refering to ch7 be the problem? Can I reset the auto calibration?

I discribed the problem On the 2.5.3 thread but haven found a real solution to the problem.

I would say that 1 meter is somewhat low for AH on its own, considering ground preasure changes.  But I see with AH after JS's statement that you need to find where the center Hover throttle point is on your quad.  Let the quad settle for a moment and then engage AH.  I do not understand if the calibration remains acurate all the time, though.

 

Jason did not comment on CH7 feature.  But for me after finding the "Sweet Spot", keeping a dome over the FC and putting a small hole in it's top (1/4'), my quad holds very well, better than my NAZA.
