Betaflight yaw spin recovery: why a clipped quad spins up, the AUTO threshold and gyro overflow detect
Clip a gate, a branch or the ground at the wrong angle and a quad can start spinning flat on yaw, warbling and climbing while the sticks do nothing. The Betaflight wiki calls this Yaw Spin To The Moon (YSTTM). Betaflight 3.4 added two pieces of code to deal with it: yaw spin recovery and gyro overflow detection. Both are on by default, and most pilots never need to touch them. It still helps to know what they do, because the wrong threshold shows up as strange yaw stutter in normal flight.

Betaflight has two settings that sound like they do the same job: throttle limit and motor output limit. They don't. Throttle limit only changes what your throttle stick asks for. Motor output limit caps what the flight controller can send to the ESCs, whatever the PID loop wants. If the goal is to protect motors and ESCs, for example when you put a 6S pack on a drone with 4S motors, only motor output limit does the job.
Read articleFPV camera angle: how much tilt to start with, how to measure it and when to change it
"What camera angle do you fly?" gets asked at every field, and the number on its own tells you very little. Camera angle is the upward tilt of the FPV camera relative to the frame's top plate. It doesn't change the tune, the rates or the top speed. What it changes is where the horizon sits in your goggles at a given speed, and that quietly decides how fast you end up flying.
Read articleBetaflight presets: how to pick one, check what it changes and apply it without losing your setup
A Betaflight preset is a short block of CLI commands with a description and a few options. The Presets tab finds it, lets you tick the options and sends the lines to the flight controller for you. It saves typing, but it writes to the same settings you would change by hand. The firmware-presets repository opens with a warning: a saved preset permanently changes the configuration, and there is no undo.
Read articleDJI QuickShots and MasterShots: what each automated shot does, how much space it needs and when it stops
QuickShots and MasterShots are the two buttons in DJI Fly that fly a camera move for you. You pick a subject, press start, and the drone climbs, circles or backs away on its own, then flies back to where it began. The results look good with almost no skill, which is exactly why it is worth knowing what the drone is about to do before you press the button. An automated shot follows a path you can't see in advance, and a few of the moves need far more room than people expect.
