Flying at night is my favorite.
I thought
Tello performed poorly at night also, as I experienced twitching, latency, lack of control, and random landing sequences when attempting to fly in low or no light. Thing was, I didn't get the best performance during the day either. Ultimately, I narrowed it down, and fixed all issues by rebooting my Galaxy S9+ every time before flying. This results in a
Tello that is responsive, and very stable, regardless of lighting. While position may drift in low/no light, altitude holds beautifully.
I made a recent post displaying my navigation lights I made for
Tello. You can find it here:

As well, you'll find a night flying session that I recorded last night. Super fun. The couple minor twitches you may see in the video were likely due to interference from my Mavic Air, which I used to record the video as it sat stationary on the top of my truck. Little to no glitches in control when night flying otherwise. Note, I rarely fly without a repeater. The video happens to be without, as the repeater had somehow reset itself, and was not configured when I set out to record.
Good luck. Let me know if I can answer any questions. Many of my most enjoyable flights are night flights. Assuming you have a repeater setup, you may discover you can fly further out (LOS) at night, than you can during the day.
