Caution re Dynamic Home Point Function

[GadgetGuy]

Dynamic Home Point is available with the RC 2 controller and Mavic 4 Pro. That's what I'm using.

That's odd. One of distinguishing factors between the controllers at launch was only the RC Pro 2 was capable of Dynamic Home point. Has there been an update for the RC 2 where they announced adding that feature to it?

That's what was my first impression, that only RC Pro 2 has this feature. I have M4P with RC2, and DJI pushed out a big update for the RC2, few days back, perhaps this DHP is a new addition. I was pleasantly surprised when I checked and found it there

So was this announced as a new feature in the update release notes?

Missed the last RC 2 update. Undoubtedly for adding or tweaking the functionality with the new Mini 5 Pro, and supporting DHP on both the M5P and Mavic 4 Pro. Good for them.

I'm sure there is also a new comparable update to the RC Pro 2 to add in the M5P to the list of available aircraft.

There is; I updated both my RC2 and RC Pro 2 to add the M5P to the list qlthough I'm reluctant to purchase an M5P since I already have the A3S and Mavic 4 Pro; my A3S has seen very little use since MP4.

I am exactly in same shoes, I have an A3S that I was actively flying before getting my M4P, I have not flow it since M4P arrival. It is a good drone though, planning to keep it.

What I am actively pursuing the RC Pro 2 purchase, but man, they ask for it more then what I paid for my A3S fly more combo package, its just crazy!

Should have purchased the Creator edition, that RC Pro 2 is nice, its what I did. Have five batteries each for the A3S and MP4 plus DJI ND filters for both, beautiful hard cases for both, backpack and all. I was considering purchase of additional batteries for the MP4 but I don't really fly that much, five batteries is enough, besides don't want to end up with older batteries.

I just updated both of mine as well, getting ready for the arrival today of the Mini 5 Pro. It is the only drone DJI now sells that does not broadcast RID while simultaneously offering many of the same features as the Mavic 4 Pro, like instant on by opening the props, rotating gimbal, Free Pano, Dynamic Home Point, Lidar, and a 10 minute improvement in flight time over the Mini 4 Pro (30 minutes even in windy conditions, based upon one reviewers testing vs. 16-20 minutes on the Mini 4 Pro), even though rated for only 2 more minutes. It's also 0S4+ when used with the RC Pro 2. It also is the only DJI drone to offer a Bicycle tracking mode. Great new addition to the fleet.

Whose Bicycle do you intend to track?

 

[GadgetGuy]

Whose Bicycle do you intend to track?

Why do you assume that I intend to track a bicycle?

I was merely citing a new DJI feature unique to the Mini 5 Pro, where it can now be used for tracking a bicycle, in addition to people, cars, and boats.
While some may use it to track themselves riding a bicycle, FAA would have a problem with that, but it isn't sold here, so it's a useful feature elsewhere, especially in combination with Dynamic Home Point, so 30 minute one way flights are possible tracking a bicycle off road. Not recommended in traffic in the city. LOL!

I can confirm that DHP is available on the RC2 with the Mini 5 Pro. My testing resulted in the drone stopping about 20 feet above me, and waited for me to perform the landing.

What altitude did you have set in the RTH settings on the Safety tab?

 

[Aeolus]

What altitude did you have set in the RTH settings on the Safety tab?

Sorry, I don't recall. I'll do some more testing and report the data.

 

[MS Coast]

It's stored in the settings on the controller.

I'm curious because I'm trying to understand how the drones sets the altitude to hover when it reaches the home point. When I tried DHP runs on the Mavic 4 Pro, it seemed to be related to the RTH altitude I set.

I performed some tests to determine the height at which the drone stops when doing a RTH with Dynamic Home Point active.

I set the Auto RTH Altitude to 30 m (~100 ft) for all test cases. I started the RTH with the aircraft at 40 m (~130 ft); 30 m (~100 ft) and 20 m (~66 ft) altitude and about 120 m (~400 ft) from the location of the Dynamic Home Point, in each of Optimal and Preset Advanced RTH modes (so six test cases in all).

In all test cases, bar one, the drone stopped and hovered at 30 m (the preset Auto RTH Height) above the location of the Dynamic Home Point, and landed within 0.5 m (~1.5 feet) of the controller location when I dropped it straight down.

Environment was a level, open area. GPS HDOP at the time was 3.8 (which implies good accuracy for GPS location).

In the other test case, the drone stopped at 26 m (~86 ft) above the location of the Dynamic Home Point. In this case, the RTH was initiated at 20 m (~66 ft) altitude (i.e. below the Auto RTH Altitude I had set) with Optimal RTH mode.

I think this is consistent with your impression that the Mavic 4 Pro's hover altitude is related the the RTH altitude set.

I agree. I'm still wondering if the DHP hover altitude is increased when there are nearby obstacles. I've not done any tests to sort that out, since I don't have any immediate need to use the DHP feature.

I just finished a flight tuning the EXP settings and I tried out the new automated camera swap when recording video. One screen touch and roughly one second for the automated change. It's much better than manually stopping video, changing camera, and restarting.
