So here it is... take some awesome hardware with firmware that is totally odd to tune and reflash it with betaflight 3.4. Stock PIDs. Quick raw rip in the yard. #love.
My personal opinion... butterflight is super smooth but very difficult to tune out issues where in the traditional betaflight methods would have been an easy fix. (And believe me, i tried for dayssss) Same exact quad/fc flashed with bf3.4 on default PIDS felt allot more responsive and locked in than butter's "odin" and was far easier to tune out the imperfections/preferences seen here.
BF3.4 hex file for the helio spring imuf fc available in the Helio slack channel.

**Im glad i did though** lol
