Hey everyone! Finished my first build ever and I’m dying to fly it. I am able to get it off the ground for about 5 seconds. After that, motor 2 ( front right) appears to drop and then the complete set loses almost all power. It just has enough to lift one or two legs off the ground and stays like that unless I throttle off for a couple of seconds. Then it’ll pop back up and fall again.
I notice that the motor that seems to drop first is hotter than the others, almost too much for the touch.
I use beta flight, have calibrated the motors, have checked for crappy soldering and other things like that, and am about to see if a screw near the coils is the issue.
Any experience with this is suggestions welcome, thanks!

Build: spf3 flight controller

oh Also I held it down with my hand and that actually worked. Haha, scariest thing in my life but I put it up to full throttle as I held it down and the motors stayed strong
