Symptoms
- Noticeable shaking felt through the controls or seen in footage
- Buzzing or rattling sound during flight
- Footage shows a rolling shutter wobble effect
- Vibration worse at higher throttle or speed
Likely causes
- CommonCracked, chipped, or bent propeller bladeEven small damage can unbalance a spinning propeller significantly.
- CommonPropeller loose on the motor shaftA propeller that isn't fully tightened will wobble.
- PossibleDebris stuck to one propeller bladeMud, dirt, or tape residue can throw off balance.
- PossibleBent motor shaft from a previous crashEven a straight propeller will vibrate on a bent shaft.
- Less commonWorn motor bearingInternal wear causes vibration independent of the propeller.
What to do
- Power off and remove the battery before inspecting propellers by hand.
- Inspect each propeller closely for cracks, chips, or bends, even small ones.
- Check that each propeller is fully and evenly tightened onto its motor.
- Clean any visible debris or residue off the propeller blades.
- Replace any propeller with visible damage rather than continuing to fly on it.
- Spin each motor shaft gently by hand (power off) to feel for wobble suggesting a bent shaft.
- If vibration continues after replacing propellers and confirming they're tight, a drone technician should check for a bent motor shaft or bearing wear.
Tools and parts

When to call a pro
If new, properly tightened propellers don't stop the vibration, a drone repair specialist can check for a bent motor shaft or worn bearing.
Safety
Use caution
Never fly with a cracked or damaged propeller; it can break apart in flight and cause a crash. Remove the battery before handling propellers.
