So I'm a real noob, and got a prebuilt as my first drone. Took my first massive crash a while back and have finally gotten round to fixing it. I had issues with motors spinning at different speeds and decided it was issues with the ESCs after some tinkering. Four new 30A multistars later and the different speeds was fixed but i was getting zero response from my transmitter (A FlySky i6). One restore to default settings in betaflight later, i had response, but the throttle would continuously increase once armed and the drone would do flips once the throttle was lifted even slightly. After fixing that issue, the drone would take off about a foot, and then do flips. This results in my suspicion that the gyro is dead. To fix this, i'll have to replace the flight controller. I'd prefer for the software to be betaflight but need some advice on what the best replacement would be, if not just to replace it for the exact same fc.
Any advice or recommendations would be really appreciated.
