There are 480 scan lines (not including overscan) in a 480p video signal.
(1/480)*16 = 0.0333...
As it will take a little less than 16 scan lines to transfer all the data (for those 16 scan lines), and as all of the data is needed to re-construct those 16 scan lines, it will have a minimum of a little less than 32 scan lines of latency.
(1/480)*32 = 0.0666...
If we take into account that there are 60 frames per second:
((1/480)*32)/60 = 0.001111... seconds of latency
that is about 1.111... Milliseconds of latency!!!
Running some numbers:
50 [km/hr] = 50.000/3600 [m/s] = 13.89 [m/s] - breakneck drone speed?
30 [Hz] = 33.33 [mS] - progressive picture frame update rate
60 [Hz] = 16.67 [mS]
100 [Hz] = 10.00 [mS]
240 [Hz] = 4.17 [mS]
Distance the drone is moved pr. picture frame update at 50km/hr, if it can fly that fast:
13.89 [m/s]/30 [Hz] = 46.3 cm
13.89 [m/s]/60 [Hz] = 23.15 cm
13.89 [m/s]/100 [Hz] = 13.89 cm
13.89 [m/s]/240 [Hz] = 5.79 cm
Doing a rolling picture update could very well induce smeering/blurring - confusing your brain

Which is why motion-pictures@24 [Hz] are/were such a big thing - it is moving a frame, pausing and illuminating, moving a frame - so no motion sickness is induced
Most people will not notice the flickering on a big screen@24[Hz] - but it is not gaming. Scenes tend to be relatively slow moving and the director is directing your attention.
You are talking about 60 [Hz] image update rate = 16.67 [mS] image update rate, and it seems you worry about 1.xxx [mS] latency and partial scan updates.
An open WiFi network should have ping rates in the 1.xxx [mS] range, and I presume you don't need encryption - your competitors won't be looking on your screen trying to cheat like it was a game of CS:GO
Another benefit is having the option of using a range extender on your network - ensuring packets are always received. No more drop-outs, though a bit of network setup is required to sort out duplicate frames. This is all about drone flying, not video jamming each other - right?
Another big requirement is your screen/viewing equipment. Does it support 60 [Hz] framerates, and even higher - without blurring the image itself?
A homemade system sounds great, expensive and quite heavy!
WiFi dongles and SBC's are easy to obtain and replace (and have spares of) in case of crashes, and it won't burn a hole in your wallet. Most are even CE/FCC certified
Looking forward to hearing more about your interesting project.
