Clear Sky (Betaflight 4.0 Dual Expo RPM Filter and Interpolated Feed Forward)

It's been raining for weeks around here, so much so that it's been flooding locally. The rain finally let up and I'm getting to do some more test flying on the latest builds of Betaflight 4.0. I've been having some hardware issues on two of the test builds I'm using, one has some pretty weird gyro noise issues, and the other had a VTX failure mid flight! Those didn't make it into this edit though :P This was mostly my Armattan Rooster on the latest build with F60 Pro II 2500kv, Aikon stack, and T-Motor 5143 props, as well as some footage running my original AMAXInno build with the RPM filtering for comparison testing. I feel like the noise floor in the newest Betaflight 4.0 builds is a tiny bit higher, but still feeling things out. The handling definitely feels sharper, and there is less prop wash in my updated configuration, but I think I need to find some balance in filtering between the two. Will keep testing!
