DJI Naza V2 failsafe question
Been flying my TBS Disco around and been playing around with failsafe, and noticed something strange it has been doing recently. When it enters failsafe it doesnt exactly come down in the same area all the time, probably within 5 feet of the take off point, is this normal? It seems to be acquiring sats fine. And also the strangest thing it does when coming down from the move over to decend to the landing it drops for a second then hovers drops then hovers and finally when it does settle to the ground it touches once for a second then hops off the ground a few inches two more times before it settles and the motors shut off. Is this normal and more specifically the hopping off the ground after it touches? This is my first quad and naza so just curious. Thanks!

Perfectly normal. GPS accuracy is limited by government so within 5 feet is perfectly within acceptability. The hop sometimes is caused by vertical gain being off but if it is only one or two light touches I would leave it be

That's pretty common. One thing you could try to help is a GPS calibration. Where you fly. Look in the manual for instructions. Pretty easy to do.

Ok.. I will do a calibration and maybe mess with the gain, currently the vertical and yaw is set at 100% the rest are at 125%....

Ok here is what I found...
Did the calibration "dance" twice outside and after the first calibration the bounce was worse, like 6-7 times. Tried the second one and it was back to the 2 times it was before. After that I tried moving the quad on a set of 6" legs and for me that was the answer. No more bouncing. Must have something to do with ground effect??

That is quite possible though I would imagine even at 6 inches high it would still be in ground effect.

Thanks for the update
