No “modification” yet …. but I got curious as to what’s under the belly-plate of the MP. So, I took it off.
I usually reduce the size of such pics, rather than post full-sized DSLR images. In PS, it’s Ctrl+Alt+I … and missing the Alt I got the “Invert Colour” function. Just posted because it looks …. cool? 
Looks Dave like lots of heat sink type compound/paste around there !.
Hardly surprising when the outside of the belly-plate is all fins. 
Is that plate a cast aluminium material?.
It’s all back together now, but I don’t think so. I doubt there’s massive amounts of heat to disperse, and even the finned plastic belly-plate will achieve quite a bit.
Interesting… I do like a good teardown 
Did you removed those three screws to peer under the main board? I’m curious as to what’s under there now too 
There are so many ribbon cables onto it, as well as the co-ax top-right, that I wasn’t going to go any further.
Also - since I don’t have any heat-sink paste (on my shopping list) I wanted minimal disturbance so that the existing paste would do something.
I’ll need to remake those sinks when I have some paste.
What is interesting, I think I’ve worked out that DJI include several anti-tamper tricks.
When I took the top cover off (some time ago) I noticed that one of the hex-drive screws had some glue in the hex. Same on the bottom plate. Now this isn’t so unexpected or tricky.
However, I (and two other people I know of) have had a problem getting out the same hex screw on the top plate, and I had the same problem with one hex-drive screw on the bottom plate. One of the hex-holes is slightly over-sized … and a standard 1.5mm hex drive fails to work easily. (Solved by leaning the hex at an angle and using it more as a key.)
Done some googling, and other people have had problems with the exact same two screws (one top - one bottom).
That is damned sneaky!
No - not mine - from a YouTube.
Actually, this semi-timelapse YT is rather good. Quite short and internals labelled. (And nobody’s talking over it! 
)
loved watching that 
looks upgradeable inside, I’m sure there will be mods going on
