POINTLESS MOTIVATION ???

Disclaimer.
Common sence and basic math tell me that what i have built is almoste pointless.
This is because i have added almost as much mass as power.so to speak.
The final figures i predict this craft will have only marginal increase in power to weight .
So why bother , I just wanted to see if i could make it work and the math does not tell the whole story.
Does it fly diferently from the standard sub 650g acro quad.
8 motors.
8 esc.( 4 individual and 1 4 in 1 )
1 f4 fc pdb.
1 vtx.
1 cam.
1 rec.
2 frames.
WTF was i thinking.
Esc config. running 2 esc off 1 signal .
1 connect and config the 4 in 1 .
2 tap the signal wires to the individual esc sssss.
3 disconnect the 4in 1 at the signal plug.
4 connect and config the singal escs.
5 plug in the 4 in 1 and test in bf .
HLFIW.
It has just rained here for the first time in 9 months and i want to fly
wednesday 21 2019 3.30 pm . 166kph in an instant.
Sounds terrifying no prop wash , feels heavy and like you just want to hit the throttle and throw it around .
I felt like a little kid swinging a big stick. Glorious and terrifying all at the same time.
Also i clipped a bushy branch and spun off 2 props and still flew home , down on power but i could not tell i was missing props.
ill be building a 7 or 8 inch rig for long distance and will be using this config.
Now all i need is to choose a long range setup.

we need an update on this when you fly it, the reliability of your mashed escs will be super interesting too

How does she fly? Does it do weird stuff when you yaw? I want you to put braces to hold the arms apart so your esc's dont get crushed, and I want you to ditch the 2nd top plate (why is it there? is it just thematic, or is it structural?).

Hi The top plate is structural and a handy place to put the battery strap..
Im also looking for some rubber balls to jam inbetween the motors for anti crush and vibe dampening.
and seeing as you look so carefully can you spot the mistake.
would have flown it before posting but tis raining here for the first time in 9 months.

Also: i've been trolling around on this site for 2 1/2yrs+ and you are only the 2nd person to post an 8 motor build like that (over and under).

I think that it would be better to use fc that have eight motor outputs.

Yes you are probably right but i dont have one

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..
