Hello everyone. Im Ranjit from Sydney. I just joined this forum. I also have tello drone which I noticed bit heating. So I did followed Flydrone's idea but little change I did that is I used 6x6mm copper pads 1mm thick. And soldered them just like the thermal pads as shown in his suggestion. Im very expert in soldering so its nice job. then I used thermal paste which is used for high end gaming pc cpus all over. After reassembly my tello is just fine. Its warm but no scary heating. Thanks to every one and keep flying.
