Listing is on CommercialDronePilots Thanks!

As far a photogrammetry (or any kind of photography) is concerned, there is no difference between the 2 versions.

P4 RTK in excellent condition. Includes shipping within the lower 48. Meet up in Western Washington preferred if practical. No incidents, no damage. Because of pricing pressure from the M3E, you can get into RTK at a good price. DJI has said the P4 RTK will be supplied with RID through a...

By "report", I just mean the visualization of the camera locations over the ground. (see a sample from a P4P mission in Metashape below). I'm not saying you will have holes in your results. If you have suffient overlap, the missing images will not effect the results. But there are misses. I...

By all means, give it a try. But it will not solve the problem. Many have tried before you. The strategy that works is to fly with enough overlap so that a few missed captures does not degrade the processor.

The OP's question is in regard to missing images in grid pattern missions. If you do fly these types of missions using a P4P and don't have gaps, I'd love to see your image spacing report.

The P4P is known for this. As far as I know, the cause has never been determined. Like @Meta4 suggested, typically, 100' agl would be considered at the low end of flight height for good coverage. That said, you should be able to increase your overlap to negate any negative effect caused by...

Howdy. The sensor on the P3P is a 1/2.3” CMOS not 1". You may want to correct your listing. Good luck with the sale !

Well, okay. I don't know why you would "hate to ask", but carry on.

You are aware that the v.1 is also dual band, right? https://www.dji.com/phantom-4-pro/info#specs

Unfortunately it is one thing that is similar between all types of society, democratic, socialistic, authoritarian. The wealthy or well-connected play by different rules. Part of the dark underbelly of humanism.

I hate to break it to you, but it's been like that for as long as ...well,...ever. For example, do you see folks snubbing their nose at congressional supenas a lot lately?? You try it and see what happens. Golden rules.

Typically to be followed up by random posts with links.

We do progress perspectives and progress 360's and we usually don't bother using an RTK drone for the job. To be honest, the information provided by the product is sufficient for it's purpose if you are close to the same camera position and use what you have to replicate the view. It may not...

You are limited by the precision of the gnss receiver. So, Litchi can only tell the drone to go to XYZ. But due to the precision problem, that can be up to 10 meters (>30 feet) different than previous. In reality, it will probably be closer than that but no guarantees that it won't be farther...
