Drone doing flips at take off

#1

Hello!

My drone will not take off! It just does a flip as soon as I take off, and I am certain my propellers are correct. As soon as I attempt to take off, it seems that one of my motors goes to 100% when the other drops to 0%. It appears that the motor shoots to 100% before the other one drops to 0%, so I think it is trying to compensate of the motor going to 100%. I have no idea why it is shooting to 100%.

I have had this quad for a bit and it has flow well before. Because of this issue, I decided to flash the new esc firmware , J_H_15_48_REV16_77.HEX to my anniversary special edition Racerstart REV35 BLheli_S 4 in 1 esc. This did not fix the issue. I have also investigated the motors in betaflight and all appear to be working fine. The orientation of my FC is also correct. I am using DSHOT 600 still, still testing if this has anything to do with it.

Any and all advice would be appreciated. Thanks!

When I had that problem, I found that my yaw was 90 degrees out which can be fixed in Betaflight. The simulated quad on the first page was moving the wrong way around when I connected it to Betaflight and you can change the yaw degrees on the right hand side of the same page , hope this helps.

It ended up being the motors incorrectly matching. My second and third motor was swapped in betaflight
