Is there a fix for not flying straight? I noticed this to today. I was trying to fly down the middle of a narrow (20 feet wide) street lined with flags. I took off in the middle of the street , went to about 10' high and started down the street slowly. I constantly had to nudge it back to the left. Before we get to far let me state that I had permission to do this. It's a city cementary and there was no one there. My bird is the P3P and is up to date. I did an IMU check and calibration about a week ago and a compass calibration at the same time. Both were successful. After the update I kept getting weak or no RC  signal warnings so I relinked the RC to the AC and it has been fine. I thought it might be my control so turned it around and flew back and had to nudge it back to the right constantly. Is there a fix? Could my compass calibration be off? Value on the compass before the flight was 1366. There are small power lines that go across the front and back of the cementary and the closest I was to them was about 50'. Any ideas?

It's probably just the wind.  I've noticed when I'm flying an initial Points of Interest pattern that I have to make corrections.  When it flies the actual pattern using the GPS it's ruler straight between points.

Try setting up a waypoint at either end and flying that. As gil says probably just wind.

Which way were the flags blowing? Do you have the video?

Now I'm confused. What in the world are you talking about? You ask me to sync my flight records and give my email address and I do. Then you ask this?

Sorry for your confusion. When I finish syncing, I get numbers of records. It would be better to point out the typical one to show the issue.

The last flight was the most noticeable. Any of the recent flights show some drifting to the left when flying away. The last flight was what prompted me to ask about it.

Thanks for your information. I've checked some of your recent flights.The drone did drift left a little bit (the drifting time was about 2 or 3 seconds) but it kept holding its attitude and responded to your command correctly. You don't need to worry about this and this issue is acceptable. What's more, I'd suggest you to change a set of new props and calibrate the IMU of your drone.

Thank you. The issue reveals itself while flying in relatively close spaces. I will try new props first. The IMU calibration seems to be fine and now it's summer I don't want to extend startup times if I can avoid it.  Thanks again!
