Noticed before the firmware upgrade that the P3P was a bit twitchy up and down while in a 15ft gps hover. A bit windy and it seemed that it was compensating very quickly for the wind. About a quick 4 inch rapid climb/decent in a hover. thought maybe its the sonar doing that. After the firmware upgrade last night and another flight today, it still did it. Maybe I will try to turn off the sonar in the app to see if it settles down. And yes I always re cal my imu and compass after a FW upgrade. Anybody else have this twitch?
