If I wanted to adapt this to a 7″ cruiser that I want to get as smooth flight as possible, which settings should be changed (to suit the size)

Thanks

It would be great if you could add the issue report to the Butterflight repo here: https://github.com/ButterFlight/butterflight/issues
Thanks for contributing!

Bug Report – with reversed motors set, turtle mode doesn’t spin the motors opposite of the normal direction. they spin the same direction. Anyway you can work this out? I’d be happy to test for you if needed.

Thanks

Citation from RCG and FB:
“In most cases Kalman will not give better results on a mpu-6000 or any 8K gyro: those have internal built in filtering (and delay) and you can already use minimal filtering in BF for them. Reported cases show adding Kalman (or BF biquad fir2) will give worse results.
On the 32K gyros the kalman enables us to get read of all the extra filtering needed due to the higher noise coming from the gyro.”
“…You can still use the fast kalman filter on 8k8k with the mpu6000…”

Butterflight is a fork from Betaflight so it inherits the same code from Betaflight. Yes the filters part is now different between Beta and Butter flights. Don’t know the exact details, but the Betaflight was actually testing the real Kalman filters in the early 3.3 versions. Then later somehow Betaflight team had moved to a different type of filter (so called “Biquad + FIR”). While they also perform very good, they are not the real Kalman filters that users were so excited for.
The decision to move from Kalman filters to Biquad filters was probably one of the reasons why the Butterflight was born.

Montis Thank You!

Thanks for comment and for early tests. Watched your Tube video and enjoyed. Looks like this Butterflight is real butter.
