Tello is becoming very hot at the bottom

[McEnzo]

Hello
my DJI Tello is becoming very hot at the bottom after a few minutes flight.
I am wondering if this is ok or do I have to worry? Please let me know!

Normal. This is where the heat is dissipated. Hence the grille at the bottom.

Normal, never had issues during flight as Tello uses the airflow to cool down. If you let it sit on the desk it will overheat to 90°C within minutes and just shutdown.

Appears to be normal. It needs to be flown to keep it cool, it will get warm/hot to the touch and will shut down if just left powered up and sitting on a surface. If its not going to be flown power it off.

Mine (Tello and Tello EDU) were at 85°C while flying. After I disassembled them and "modified" the thermal paste they used I got better temps but still not ideal.

TL;DR: Absolutely normal. If it gets too hot it will auto-land and shutoff so nothing to worry about.
