Drone throttles up on its own (real flight not Betaflight)

Hi Pilots!
I'm having a hard time diagnosing the problem with my first self built drone.
It seems like the throttle is always going up on its own after a few seconds of flying, I've tired Acro/angle/horizon mode and it does the same thing. I've reflashed the FC too.
On the video I cut the motors as I felt it speeding up on its own, as this has happened on all my test flights.
the one thing I haven't touched is the Tuning as I'm still learning about this. (and most other things about fpv)
I'd appreciate it if anyone can't point me in the right direction
✌️

If your FC supports black box logging suggest turn it on and get a dump of the blackbox logs posted on google drive or directly here if you can so can check out what's happening with the receiver input and gyros etc. when it decides to go full throttle. In general would say double check just using right stick that all directions are working correctly and make sure the FC is "soft mounted" that is it has some small rubber rings between the FC pcb and the stand offs/screws holding it in the frame. Often if the FC is getting rattled by the screws the gyro will be getting knocked around and cause the quad to react in glitchy ways. Blackbox logs help eliminate any chance of receiver input being interpreted incorrectly.

Thank you, I will try to lose up the screws, I'll also check if I can turn on the blackbox, I'll post some updates!
