so this has been bugging me for a while and i cant figure out if its a tune issue or something mechanical. quad flies ok, like its not unflyable, but there's this weird feeling at mid throttle when i make quick direction changes, kind of a mushy delayed response thing. hard to describe honestly. oscillations arent visible in video but it just doesnt feel crisp the way my last build did.

running 4S, 2306 motors, props are hq 5x4.3 which ive used before no issue. betaflight 4.4, default rates adjusted a bit but filters are basically stock minus dropping the gyro lowpass a tiny bit. blackbox shows... something, im not great at reading it yet so i kind of just stared at it for 10 minutes and gave up.

is this just a P term thing or could it be something else. rebuildt the quad recently after a crash so wondering if somethings slightly off physically too but everything looks straight to me

that mushy mid throttle feeling is usually either propwash that isnt super obvious visually or your D term is too low letting the quad drift a bit before correcting. id bump D up a bit first before touching P, its usually the safer adjustment and often fixes that exact feeling people describe. also double check your motor screws after a crash, even one slightly loose motor will mess with how the quad responds in ways thats really subtle and hard to pin down.

blackbox is worth learning even basics, you dont need to understand everything just look at the gyro traces and setpoint traces overlaid and see if theyre tracking each other. if theres a consistent lag that tells you something about your filtering being too agressive. theres a good video by Joshua Bardwell specifically about reading betaflight blackbox for beginners, think its a few years old now but still mostly relevant for 4.4.

also what FC are you running? some of the cheaper ones have gyro noise issues that filtering alone doesnt fully fix and a rebuild is sometimes when people swap parts and dont realise something changed. had a mate swap to a different FC mid build and spent two weeks wondering why his tune felt worse than before.
