i just put this up in case someone finds it interesting and want to give it a try.

use whoop board to look better. weight is important, don't add more weight to it.
use 16awg wires for pigtail and battery lead if you want more power for power loops.(tattu 3s 450mah or talon nfg 3s 450mah)

41g dry. frame 6g, 1102 with 1mm shaft.
betaflight 4.0.3
copy and paste betaflight community presets ( https://github.com/betaflight/betaflight/wiki/Community-Presets)
TPA: 0.40, 1500
"Clip", not scale, 60% for testing ( don't know if you want it more, because those motors are 1102 9000kv on 3s ), 6000kv-7500kv would be better.

whoop board setup: i lowered P gain to R: 25, P: 28, TPA: 0.80, 1500

6/23/2019: 6 minutes of boring flight. don't watch. you can fly a lot better than that :) i can go on for another minute if i want to.

first flight. i still need to get used to it. it has good acceleration. analyze how fast ( or slow ) it is. and decide if you want to try it :)

for 2s, same build. for those who want 2s. 27g 2s 450mah-525mah batteries.
betaflight 4.0.3
copy and paste betaflight community presets ( https://github.com/betaflight/betaflight/wiki/Community-Presets)
R: 55, 78, 37 ff:70
P: 55, 85, 40 ff:70
Y: 35, 100, 0 ff:0
throttle limit: "clip", 90 ( it should be ok with 100% throttle, i just don't like 100% in any setups :)
TPA: 0.80, 1700

here is 2s flight. nothing interesting, but just to show how it flies.

nice! sound :-)
looks its enough powered. how is it on a tiny track, technical track nimble turns, precision flight? if you could make a video in this direction, would be very nice.

1103 are a better fit for these props. but no one would buy those old kingkong 1103 with 1mm shaft.
so, this 1102 setup is a second best build for those props.
the focus of this setup is something really light but have good speed to enjoy in wide open space. of course, with small motors you have to give up something for more speed and that is the low end control. but then it fits where i'm flying, in a park and wide open space.
i don't fly well, so it's hard for me to show how it flies. i hope someone would make this build and leave a link here to their builds or videos. so people can have a better idea. for example, one of the build i put up, 2s 1103 hq3x3x2. watch the videos on that page and compare those to this ( flight at end of the video and this is not my video) :)

You mentioend the 1103 is a better match for this 3 inch prop than the 1102, how so?

1103 are more powerful, so they fly faster and can handle this prop better. better experience overall. still, this is the fastest 3s 1102 ever ( it needs to be 3s for both 1102 and 1103, or you would feel the prop drag ). they are the best props for 1102 and 1103, better than all bi blade 65mm props, in terms of speed, efficiency and handle. with all that said, they are made of bad materials and have 1mm shaft and they come to you bent up and down and all over. it's too bad the company doesn't care.

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
