I upgraded my P3P, app (on iPad mini2) and RC.
RC asked me to upgrade again...did get that!
Did an IMU calibration. Calibrated compass. Gusty day, phantom was jittery and not very keen to stay put. Responded weird to control input, like, I would slowly bank it left, then applied a bit of right stick but it kept drifting left. Aggressive inputs would respond accordingly.
Brought it down, rolled back to 1.6...still a bit jittery, still not going exactly where I pointed it and drifting sideways, still responding weirdly to control input, but less that with 1,7.
Tried going a couple of times between 1,6 and 1,7 and getting consistent results. Did a couple of IMU calibrations...
I'm not sure if it's the gusty wind messing my flight or the drone itself, but I've flown in harsh wind and it felt much more solid in the air and controllable...
Not sure what to do...1.7 gives me less confidence, 1.6 seems kinda ruined too, and it feels strange to me having the RC and APP up to date and not the drone...
Strange I upgraded mine from 1.6 and have not encountered the same. I did not do a IMU calibration. I dont do IMU calibrations unless it fails the check IMU or the values displayed are out of spec after upgrades. Not a big fan of IMU calibration in my circumstance as it is difficult to find a good spot that is free from disturbance in my area.
