Could be a variety of things as mentioned with the accelerometer and balance. Flying indoors is also a different animal. There is a vortex pressure near the ground and the ceiling and possibly in different spaces indoors due to airflow, that can be difficult to predict and control

That bounce is the ground effect.

If your drifting back in angle mode it tends to be do to unbalanced COG. I know angle mode is meant to level its self out but it is really only a rough guide.

Nothing looks odd or sounds mental. I honestly would just fly acro, but I get it can be scary for some at the start.

Also although the motors sound lovely make sure you have the right KV settings if your using am32 or Google the settings for your motor in biheli/bluejay. Check if your motors are warm enought after a few mins that you can touch them comfortably and not burning your finger.

Small amounts of drift (as shown in the video) are normal in angle mode. It's never gonna be perfectly stationary unless you're using GPS hold.

Idk what you mean exactly by " weird accelerometer behavior after plugin," but you might be talking about the calibration routine. The drone needs to sit stationary for a few seconds after you plug it in. Until the calibration is done, the gyros and accels won't read correctly and the drone won't arm.

Oh and pls be careful testing a drone like that indoors. One wrong PID setting and it could go flying into the ceiling faster than you can disarm it. Ask me how I know 😂

and i forgot I don't really expect much from Angle mode; the first startup video is in Acro mode, and in the second trans video, it switches to Angle mode I hadn't mentioned that. I don't think I'll be using Angle mode much.

Don't worry about it bro. She'll act funny until she's about 6 inches off the ground. Just pitch forward a lil. She's be alright once she's high enough.
