Today I got to video a steam railway, and I was taking the Air 2s down the line at platform height, and two things I noticed:

1. In sports mode the drone naturally gains height (the track wasn't level but the drone increased height quickly).

2. I have issues with keeping it in a straight line. Right stick forward and it's slightly moving to the right. I thought maybe it's my thumb, but no. Barely any wind either. When I correct it with some yaw, it will soon drift off again.

I'm aware you need to be dead on to fly straight and that's impossible, but the controls just don't seem to be nuanced enough to get a near straight flight. Obviously up high, you don't notice it as much.
Any tips?

Cheers!

Sounds strange, did you have enough sats (15+) connected? Mine flies quite straight, though I almost never fly in sport mode.

hi,

Try to disable sideways flight and fly again.Number of sats has no effect on flying straight or not....

Log shows the RC inputs and many more flight data to check for this issue.

I would,
1) calibrate the controller
2) have a look at the EXP setting, (probably needs a fairly recent version of the app, I think the facility appeared in one of the 1.5 versions.) The consequences of the settings are depicted as a set of curves, the stick position being plotted along the horizontal axis and the response plotted along the vertical axis. The greater the gradient at any stick position the greater the change is response for a small stick movement.
Generally the default settings produce a shallow slope near the origin (0 stock, 0 response) but the slope steepens as the stick is moved away from 0. This means there is only a small response to small stick movements e.g. 2deg of stick movement, near stick 0, but, for the same amount of stick movement i.e. 2 deg, a much greater response elsewhere along the sticks axis where the gradient is steep.
In terms of avoiding unintentionally adding of roll or yaw to intended just-forwards/just-backwards & just-climb/just-descend this would be good but I dislike the variable response rate that it introduces so I set mine, numerically, to 0.5. This produces a straight line graph and a constant rate of response change for a given stick movement but it does make it difficult to avoid introducing unwanted roll and yaw.
3) Go to https://www.phantomhelp.com/logviewer/upload/ read the instructions there on how to retrieve the flight log. Upload the flight log to that page. You could then either post the resulting URL here and allow us to look at your log or you could download the csv and open it with a spread sheet program, then do a search for "rudder" and you will find a group of column, possibly CL to CO, whose titles contain Elevator Rudder Throttle Aileron.
These are the stick positions, you would need to work out which value corresponds to stick 0/stick-centred but it is possibly 0, the further the shown value is from that value the further the stick is away from centred.

I always prefer to fly forward.  Flying straight is too much stress.

I had same issue for a while then it mysteriously went away...

Upload you’re logs. I checked mine and was moving the stick slightly left or right. The elevation change defiantly shouldn’t be happening if you are not touching the left stick.

I've found it easier to fly straight by using the pinch method vice thumbing.  In reviewing flight data I found that I was ever so slightly moving the stick when using the thumb method.  Now using pinching method I no longer have an issue to fly straight.

Had 12 sats, but it's never flown straight that well.

I've checked logs and I use the pinch method too, nothing showing I'm pushing to the side. I think it's a controller issue tbh.

I've looked at the logs, it's the right-stick. When it's centred the drone flies a little to right. Some issues with construction perhaps.

And yea it rises no matter what.

Thanks! I'll check that out.

I had this issue and it went away after I calibrated the controller

Sounds like you have narrowed it down to the RC then.

Ok.. I've got a lot of time on my old Mavic Pro, and still learning my new Air2S, but I did read something about adjusting the gimbal to look to the side by touching the screen.  Could your camera be looking to the side when you are lined up with the display?  Hey, grasping at straws here....

Hello there b9y. I am sorry for the trouble this has caused and thank you for reaching out. Kindly please try to calibrate your DJI Air 2S remote controller and may we please know if you are receiving any error message on the DJI Fly application as well when this is happening? Thank you.

myabe it is a just wind issue

I did a calibration and tested that out, but figured out it's an error with the controller.
