the esc at motor #2 is hot to the touch just after plugging in power. also, the first flight it fell out the sky just a few seconds into the flight and subsequent arms did not spin the motor at idle. got a replacement esc but the problem persists. swapped motors #1 and 2 to rule that out, no change. what are the chances I have two bad esc parts?

the flight controller was also replaced but the issue remains. i have since ordered a 60A 4-in-1 esc so ill be installing that when it arrives this week. since the fc and esc is replaced while the motors were swapped with a known good one, i am unsure what else i may try if this doesnt work

With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
