Precision Landing Problem

ArduCopter Copter 4.0
1

Hello everyone,

I upgraded FC firmware from v3.6 to v4.0 several days ago.
After upgrading, I found that Precision Landing works differently from that of the previous version.
The distance error to the target is larger than before on windy weather. It looks like it doesn’t control a drone when it approaches the landing point. (please see the attached parameter file)
There are some additional parameters on v4.0 and should I set parameters for the better performance?

Thanks in advance.

Is there anyone who have tested precision-landing on Copter 4.0 ?
There is no change in parameters for PL but I am wondering why it doesn’t work like the previous version.

We are testing now. An exact fit does not work properly. Never managed to board the lighthouse. I think either roll back the firmware to 3.6.8 or switch to PX4

Switch to PX4 is the worst advice i think :slight_smile:
