Here is a central place for the sharing of Betaflight related flying tips or full tutorials, which could be invaluable for newcomers and advanced pilots alike.
How To Fly An FPV Multirotor In Acro Mode
Joshua Bardwell's excellent series of 27 lessons that use the free FPV Freerider simulator to teach a complete beginner how to fly an FPV multirotor in Acro mode (no autoleveling). A great resource for those wishing to transition from Level/Horizon modes to Acro mode.
Making coordinated turns in Acro mode
In autolevel modes (Angle or Horizon), the flight controller attempts to maintain a fixed angle of pitch or roll which is proportional to the stick deflection. In Acro mode this assistance is not present and the pilot needs to compensate manually. This video explains how this is achieved in flight.
How to Fly FPV Quads
Jack FPV is new to the hobby, but is learning fast. Follow his series of FPV videos as he teaches us how to fly in the Liftoff simulator and also in real life.
