I flew a friend's P4 on the weekend for the first time as I own a P2V+. I found it really sluggish and lacking responsiveness. I clicked it to sports mode and the acceleration didn't seem to change. In Atti mode in my p2V+ I can crank the speed and give it a good whirl. I didn't feel that when I flew the P4. My friend hadn't done the updates so is this the reason or have DJI slowed everything down? Just curious.
