Oscillations — fast, high-frequency shake

A fast, high-frequency shake or buzz is visible in flight or in blackbox logs.

💡 The idea: This is almost always P set too high, or noise feeding the loop.

Try these in order

Make one change at a time and re-test — that's how you learn what your car likes.

  1. 1
    Lower P gain

    The most common cause per the Betaflight PID guide.

  2. 2
    Check for mechanical issues (bent prop, loose motor) first

    Mechanical noise can look exactly like a PID problem.

  3. 3
    Review gyro/D-term filter cutoffs

    Insufficient filtering lets noise feed the control loop.
