Excessive motor RPM on drops

What is your Motor Idle Throttle Value (dshot_idle_value) set to? Make sure it's high enough so the motors RPM doesn't go too low and they can respond fast enough.

If you have Bidirectional DShot you may also want to set up dynamic idle (

I also noticed that during the first part of your flight where you're flying smoothly the logs show a fairly constant pitch I-term around 5, and motor 1 and 3 run slightly higher than the others. This tells me you have a bit too much weight in the back of your kwad. Try to move the battery forward to keep the center of gravity perfectly in the middle of the 4 motors.

Hi coyote, interesting problem. In the logs I see that around 1:06 motor 4 goes completely to 0%, that's not normal. After that I see the yaw I-term freak out quite a bit which is to be expected when only three motors were running.What is your Motor Idle Throttle Value (dshot_idle_value) set to?

That way you can prevent any motor to go below a specific RPM. With Bidirectional DShot I'd also recommend to use "set debug_mode = DSHOT_RPM_TELEMETRY" in your config so your blackbox will log the RPM of the motors.I also noticed that during the first part of your flight where you're flying smoothly the logs show a fairly constant pitch I-term around 5, and motor 1 and 3 run slightly higher than the others.

Also, it’s important to address the potential repercussions of excessive RPM on your motors, especially during sudden drops or maneuvers. High RPMs can exacerbate the wear and tear on your motor, leading to premature failure. Consider investing in quality drone rpm parts that are designed to handle higher RPM demands, keeping your setup robust and reliable. Each component from the stator design to the bearings plays a critical role in maintaining performance and safety.

Make sure you also regularly check the drone equipment to ensure everything is working as intended. Proper maintenance not only extends the life of your motor but also keeps your flying experience smooth and enjoyable.
