I have just finished building a 110mm quad and have noticed on the first few flights that the motors are getting quite hot, even after a very short hover. I have spent a bit of time PID tuning and it seems to have reduced the temperature a bit, but I’m still a noob and don’t really know how to tune properly.
Can anyone give me an idea of whether this is a problem, or something that can be tuned out, or should I just not worry about it.
Here is the parts list:
- GEP-HX2 Hummingbird Quadcopter Frame
- MiniCube F3 Flight Stack
- BrotherHobby Returner R3 1106 5100KV
- Turnigy Nano-Tech 460mah 3S 25~40C Lipo
- RacerStar 2035 4-Blade Propeller
- Betaflight 3.2.3
Here is the dump from Betaflight
