i highly recommend toothpick style builds over this. this is just for fun.

1/24/20: great news. Alexandre Arvinte just made a frame and camera mount for this setup. i really want to give it a try. no one has that frame yet, so try it at your own risk. or just wait for me to try it first :)

1/20/20: i cut down the standoffs again. now they're 9mm from 11mm. i could cut them down some more, but i would need a custom frame for it which i don't know when i can have one.
+++ still trying to find props for 1102. you might wonder why not just change to 1103 and have more options for props. well i just want to work with 1102 for now. and i will try 1103 later. and i don't want to move to 1105 or bigger motors. this is just meant to backyard.

1/19/20: i cut down the standoffs. now they're 11mm from 15mm. i feel it's very crucial for this tiny top-mount build. the shorter the arms the lower the batteries need to be. it's just my opinion. i don't believe i've seen such low profile like this for 2inch quad. but if you have see it, please let me know, so i can learn and improve my build.
+++ there is no need for me to keep the bind and boot buttons so i took those buttons off. i can use " BL " cli and " bind_rx " cli commands. bl 4.1
+++ hehehe i put those commands here so i don't have to remember. because i keep forget them.

i foam taped everything down :) there is no mount for whoop boards.

don't expect it to be fast. it's just a backyard flier. if you fly in a park, big space, i think 2.5" or 3" quads are better.

41g dry ( 3g heavier than happymodel SailFly, i think )
frame: Rotorious FPV LB97 ( very light 8g, i think 8g is good enough for top mount 1102/1103 )
motors: Geprc 1102 9000kv ( it's the lowest kv they have. i would go for 8000kv )
esc/fc: CrazyBee v2 ( anything is fine really. 5A should be enough )
props: hq2x2x4 ( chopped down to 2 blades ), i'm still trying to find props.
cam/vtx, mount: RunCam nano3, tbs pro32, custom mount ( total cam + vtx + mount = 3g )
camer mount is designed by Alexandre Arvinte,
batteries: 2s 450mah (27 grams )

it's not a good day for dvr.
i'm using default betaflight 4.1 still have some propwash but i just want to fly and not care.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

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..
