Welp, update. Three IMU calibrations and one obstacle avoidance sensor calibration and the issue persists :
Have noticed that the props will sit there and spin for a while, sometimes longer than what might want or need depending on where and what doing. Next time they just sit there and spin, try pulling left stick down, right stick down and to the left and motors stop. Stumbled on this by accident, it may or may not work.I'm sure you have but....have you tried just leaving the sticks in the middle after it lands to see if it will shut down? Mine occasionally takes a long time to shut down or won't shut down when sent the stick shut down command so after landing and sending the shutdown command via the sticks I then return them to the center and just wait.
Also, at night does the spotlight turn on as you get closer to the ground? Maybe the downward sensor is not working properly.

Nope, when I get the Gimbal not ready message, I hold on the ground and wait until it clears before trying to power up. I cant remember ever doing an auto takeoff with the E2P, or if I did, it was only once or twice over a year ago when I got my first EVO. What I have seen is upon landing.You sure you're not getting a "Gimbal not ready" message? I can't take off when that error appears either, but the auto takeoff button seems to bypass it.
You should also try an RC calibration.
By drifting or not shutting down the motors? Are you holding down the throttle until motors disarm?
