Landing of my P4P is slow and halting

[Mo of Pocatello]

My P4P now won't descend fast at all. It only descends very, very slowly and pauses all the time. What's wrong? Thanks.

I tried to get the txt flight log out of my iphone, but i-funbox says that "Jailbreak" is required. What do I do? Thanks!

OK, here's a log of a flight made with Litchi. Same thing happens (apparently) when flown with DJI Go 4. Thanks! DJI Flight Log Viewer - PhantomHelp.com

Here's another log, this time flown using DJI GO 4. What are the VPS and IMU altitudes? DJI Flight Log Viewer - PhantomHelp.com

Could be a downward sensor issue. Disable those and see if that solves the problem. They may just need a good cleaning.

You're right. The gimbal guard was the problem. So I removed it for good and recalibrated all the sensors.

What are the VPS and IMU altitudes?

"IMU" is the altitude based on data from the Phantom's barometer. "VPS" is the altitude calculated by the sensors on the bottom of the Phantom.

you were flying with the gimbal guard on?!?

good grief, people.

Why not? This gimbal guard was made to be flown with, but the designer must have forgotten about the downward pointing sensors! If you've had a Phantom 3 Advanced drop from the sky because of battery failure like I have, twice, you'd understand why I would use a gimbal guard.

That makes sense! I can now see from the second log I posted that the VPS stayed near 0 while IMU was a relatively high value!

You're kidding right? You never fly the P4P with the gimbal guard on!

 

[Mo of Pocatello]

No, I was serious. What's wrong with a gimbal guard if the sensors could only bypass it!

omg [emoji50]

In what alternate reality did you ever get the idea that it was OK to fly with the gimbal guard on? I'm guessing you are just trolling us as a joke as nobody would intentionally do something so ridiculous and foolish on purpose!
