I.. both respect and absolutely abhor what you’re doing
#Great Pyramid Anhedral Quad

How big is this frame? Having a hard time figuring out the scale

not sure why angling them so they work against eachother would make it faster?
unique jacinth
a turbo charger forces more air in a chamber, thus increasing the oxygen level for the combustion, so not really comarable.
edf are mostly about the airspeed, and the gain from ducting with sizes used in models usually isn't that great, the reason they are used in models is mostly aesthetics & size
ground effect is mostly interaction with the ground that lowers the drag on the wings
i don't necessary see how any of those compare.
but lets for a moment look at what you say you want to achieve:
you assume that angling the propeller pulls in more air.. why?
you claim compression - but there is not chamber that the air could compress against, so it will go the path of least resistance - feel free to give a source reference to explain the fluid dynamics you seem to believe countering that.
but unless there is some really cool effect in play here, the energy you lose from having thrust vectors in opposing direction, I don't think you'll harvest much here
long silo
Is it possible that it will help against propwash? And against VRS?
unique jacinth
it looks cool, although it will need to stand higher for the props not to strike ground

Or only fly in Egypt?

No Betaflight FC is going to expect to be shaped like an Egyptian tomb, just turn the PID controller way down
It's not going to fly well (stable with low filter) but that's to be expected
I also agree that you won't get more energy than a flat quad. Collision of airstream has too much energy lost in entropy - in a perfect world you'd only get the same amount of power.
It's also related to the interfering airstream and different center of mass - which introduces way more entropy. A lot of propwash.
I don't have a mouse so I cannot draw a diagram. But a flat plane quad has the most torque for rotating.
If you draw a tangent anywhere on the center of a circle, it will always be perpendicular to the line from that part to the center. Any other line is not going to increase thrust...
Why?
Even so. If you treat them as the fulcrum, a prop that is directly perpendicular to the center of mass + fulcrum has the most torque
Oh, it's not a gif...

I forgot to elaborate on this: turn master multiplier down is what I mean.
I've not been in a course where torque changes in any frame of reference.
However, this is one of the most unique builds I've ever seen, so I ask for you to send a video once it gets flying.
Material? Including whatever's holding the joints together?
braided fishingline and glue...
you're gonna have to run more filtering, I can assume, without looking at a blackbox
jagged horizon
is there a reason you left a void under the frame?
i feel like it could have been built stronger
wary flare
Cool. I want to see this flying.
tight oyster
same

more liftoff force right
you can downgrade to a small motor with the same power, reduced battery life tho
long silo
At least it flies! And as I can see, you haven't to travel to Egypt for every testflight
scarlet ledge
have one-switch arming with horizon mode enabled. Chuck and arm

Wow sht that's fking fast

Looks nice!

You should make it an upside down pyramid 🤓

Did you see the video of the world record fastest drone ?
strange heath
This is a little to complicated for me
strange heath
I wanna see a video of that thing going hard
hushed wyvern
will the fpv cam be mounted on the top?
https://youtu.be/szxRORFl_lc?si=u20ZBlUfDKO9bDOu
I have no idea if you have seen this video, but its very interesting
strange heath
A stubby antenna at that sticks trought the bottom plate ? (Axii stubby antennas are great)
strange heath
That could work but I don't know how the signal wil be
strange heath
Maiden when ?
hushed wyvern
Not sure if you would see a lot trough the top plastic camera thing. As it has 4 non see through lines
Other than that it looks really nice
strange heath
Whyyyyyyh
hushed wyvern
Im not a specialist in aerodynamics but maybe this part could cause a lot of drag.
Although I dont really see a way to fix it as the propellers sit there too.
strange heath
Thanks for translating I don't know a word german
hushed wyvern
Would be amazing to see a test flight tomorrow!
You're drone definitely has some very cool and special looks. Any way on how you will prove that your design concept of the angled propellers creating a negative pressure effect does indeed improve the flying characteristics and topspeed?
hushed wyvern
I'm very excited to see a video!
strange heath
Weird are u using the m10 chip ?
long silo
Did you solder the shield to the ground?
hushed wyvern
Whats the highest flown speed on this?
summer scroll
can you fit bigger props in a smaller foot print like that ?
arms too thin you have vibration problems

can you fit bigger props in a smaller foot print like that ?
if thats the case could be verry intresting smaller arms better vibration and realy much more air
summer scroll
Mini quads need stiffness, Long arms are one of the main problems of bigger propeller sizes.
So if you can use shorter arms for bigger propellers it is a major advantage
icy gust
anyone still knows whats going on with this design?
you aren't going to get any news from him
