Hi all. Some advice or suggestions needed. Yesterday I was shooting stills and video for a school. The web people asked for some pan and tracking shots along the front of the school and over the property. As with many urban schools, there were houses across the street, overhanging trees and a line of small trees near the curb the length of the property. I planned on using Course Lock to do some of this so I could lock the bird on a line parallel to the school so I could rotate the camera (drone) to face the school and do long tracking shots. The idea was sound, but in practice I found that I wasn't just pushing the left stick forward or back, but kept veering it slightly to the right or left so although it held its forward movement, it would creep towards the school or trees. I know here are some accessory products that help keep the stick on a line. Or maybe there's a technique for doing this. How do you (whoever actually does this) keep flying on a line when its critical to do so? Also I need to slow down my rotation I forgot which setting will do that.
