Hi DJI, is there any chance you will correct the "crabbing" issues which all of your current flight controlers possess?

By "crabbing" I mean the copter is meant to follow a line from point A to point B. Instead of facing directly at point B the copter flies at anywhere from Zero to 20 degrees to the left or to the right.

When performing a survey pattern the copter can face perfectly on one strip, then on the next crab 20 deg right than back to zero on the next.

Problems with this are

1) you do not get proper overlap of the photos
2) when the copter is facing left by 15 degrees say but then has to make a right hand turn it makes a VERY wide turn because it is facing the wrong way to do it.

Really this is my only beef with these controllers and if you fixed it this would make many people very happy!!!!

Any comments welcome even if it is an official "no we are not fixing it"

Please don't comment that this is not an issue or it is my setup or that I should rotate my compass. This is a proven problem.

Which flight controlers possess you know have this issue?
And what about the version of firmware?
Does the same thing happen when you fly a straight line without GroundStation?

I have the same issue. Didn't hurt me that much but I've always taught that the wind is responsable for this. If we have constant side wind it's blowing the copter away from it's route and since it's trying to compensate it rotates a bit around it's vertical axis.

Though, a multi rotor copter can just as well (better) bank (lean) into the wind to compensate for side wind drift. No need to yaw. This becomes even more important if using a camera in "FPV-mode" (look straight ahead).

I am trying to get the same shot but cant find the setting in the new ground station feature to change the heading. Doe anyone know if this is a planned software update?

Hi there, it was with the WKM controller, we have since upgraded most machines to A3 but awaiting support for a ground control station.

Good to hear you were able to find the cause. For the new Ground Station, had you already looked into being a part of the BETA?

Hi there we did not find the cause. We just don't use WKM anymore.

I have applied to the beta GCS three times with no response.

for S900 + A2 - This problem can be decreased with increasing Basic YAW gain value from  120 to 130 or even 140.  This helped me , Also, Hold the Vehicle for 2 Sec at the start of the flight line, this will stabilize the Yaw to 360 and then it can start the forward motion.
