i just moved and finally got my drone unpacked. was gonna fly and thought about updating to new betaflight. i have omnibusf4 3.5.5 from jan 2019 and it been flying good. i updated to newest firmware and input all the settings back and it totally screwed up everything. good thing i was able to revert back to my original set up. what do i need to do to get the newest firmware to fly properly...also what happened to air mode on a switch???
