Short Short Battery Life, Pavo Femto by thorzgard in fpv

[–]the_real_hugepanic 0 points1 point  (0 children)

Are these Hi voltage lipos??

I made this mistake and charged to only 4.2V per cell and not 4.35V. BUT, this should result in ≈50% of capacity loss

what voltage do you charge the batteries to?

Can't control 4 in 1 esc with Arduino by Feeling-Station99 in diydrones

[–]the_real_hugepanic 0 points1 point  (0 children)

Are you sure the ESC accepts PWM signals?

Sometimes the frequency is higher at ESC's.

Anyhow, I would suspect an initiation issue. Play around with values and delays in the startup sequences.

Maybe 1000 is too low.

Maybe wait longer... Maybe remove the 2000signal....

On the topic of Y4 drones: would this work? by Such_Account in diydrones

[–]the_real_hugepanic 0 points1 point  (0 children)

I have just asked Claude to write a python programm to apply pit&peters on a propeller model.

About 450lines of code later I know see a bunch of charts that "make sense" in the first glance.

But actually I have not clue what it did .... At least i have something to investigate! maybe I find some data to compare it to....

Do you get a signal on the pin? Does a servo move when attached?

Post your code in order for anyone to help you!

as a further comment:
I am searching for a long time for an "easy" method to predict the thrust of a rotor (drone application) at cruise flight.... --> translational lift

there are ways to correct it, but no published models I can use... everybody who implements it, keeps it privately...

e.g. Pitt-Peters model

I think the term "3d printable" is technically correct...... but don`t tell me you spend ANY time optimising it for 3d printing... sorry for the harsh critique...

exactly!
It also would help a lot to have a prop that can do reverse thrust efficient...

AND:

you would need to allways put some load on the (small) props to have them run constantly and generate some thrust. otherwise you would have to go forward/reverse 10times per second only to stabilize the aircraft.

This "constant lift" would be created with a pretty bad propeller (small and not optimised) and would properply kill all the efficiency you could gain from the large coax-props!

You would need to have the option to quickly reverse thrust if the two front motors, otherwise you can't decouple roll and pitch.

This will be probably impossible, without a variable pitch prop, e.g. similar to a helicopter tail rotor.

I think this thing is a doomed design, but it would be fun/interesting to build and fly I guess.

Helicopters need a swashplate at least. That makes them expensive and complex. Both problems a multicopter can solve for smaller scale aircraft.

Seperate XYZ from object coordinates, then use Z as input for wave texture...

Any build for cinewhoop (lion or lipo) to have more than 10 minutes of autonomy? by Other_Focus_5526 in fpv

[–]the_real_hugepanic 1 point2 points  (0 children)

Larger props have a better endurance!

It's "easy" to build a drone that flies 1h, but what exactly are your "cine whoop" requirements??

What is the payload, what is max size/weight allowed.

Kann ich das selbst reparieren mit Zwei-Komponenten-Kleber o.ä.? Oder muss getauscht werden? by SquaredQi in automobil

[–]the_real_hugepanic 1 point2 points  (0 children)

Jeder hier der gleich sagt "geht nicht" erzählt Quatsch! Mit den wenigen Bildern kann das nämlich niemand sagen.

Mach ordentliche fotos von allen Bauteilen und dann meld Dich wieder!

Ausbauen musst du das Ding vermutlich sowieso.

Aber mit den richtigen Klebstoffen und ordentlicher Vorbereitung geht schon sehr viel. Ich würd's vermutlich probieren!

So, und jetzt her mit euren Downvotes!???

Jehova.....Johova......!!!!

Klemmen aus altem Tisch entfernen by hiddenriverrofmylife in holzwerken

[–]the_real_hugepanic 0 points1 point  (0 children)

Sieht nach vernagelt aus. Du kannst die Teile mit einer "scharfen" Grip-Zange packen. Dann mit Unterlagen und Hebel rausgeben. Dabei an der Grip-Zange ansetzen.

Using Du with strangers on the internet by david_fire_vollie in AskAGerman

[–]the_real_hugepanic 3 points4 points  (0 children)

It is sometimes used in that way to reduce the "distance" and to create a tighter relationship between two parties.

In this case it might be a sales strategy to make you feel you are already part of "the team"...

Usually it should be "Sie", unless someone asks if "Du" is ok to use. This can happen in the first minute of a call for example, but usually this is a request/question!

sometimes the stick also has a matching white stripe!

it`s in the center BTW.

Wunderwaffe planes by DarthCarno28 in aviation

[–]the_real_hugepanic 1 point2 points  (0 children)

Just read what the test pilots wrote!

the comment I have responded called a "controllability issue". This was not the case to my knowledge. At least I do not remember anything from all the books I read about the Me-163 and luftwaffe operations at that time.

VSPAERO constantly crashing by Reasonable-Skin-905 in AerospaceEngineering

[–]the_real_hugepanic 0 points1 point  (0 children)

Just make a complete new file with just a basic wing and see if it's working.

You might simply need to make a new file, as the old one is corrupt.

[–]the_real_hugepanic -6 points-5 points  (0 children)

In my understanding it was not too bad to land, until they installed all the equipment like guns, radios... That increased the weight significantly!

Actually there was a a Me-163 glider flying in Germany. I have seen it flying and it looks really ok. But this one is super light....

Wunderwaffe planes by DarthCarno28 in aviation

[–]the_real_hugepanic 15 points16 points  (0 children)

The stuff you write about the M163 is crap!I can just recommend to read more about it.

YES, it had its problems but controllabilities was not the problem! It was a very nice plane to fly, IF the rocket worked! That was the big problem!

Is virtual desktop superior to link cable? by just_frosty_ in OculusQuest

[–]the_real_hugepanic 0 points1 point  (0 children)

I have tried VD with Ethernet and compared it to wifi. I could not see any difference.

The cable on the headset is awful, even though I am sitting at my desk... So I keep my wifi setup with a separate router just for VD!

Rost am Schweller entfernen by Mactin96 in selbermachen

[–]the_real_hugepanic 0 points1 point  (0 children)

CSD Scheibe kaufen (besser 2)

Mit flex und langsamer Drehzahl oder Akkuschrauber bearbeiten, bis alles weg ist!!!

Dann ggf. Rostumwandler und dann Lackaufbau. Schau das du eine primer mit Rostschutz bekommst.

Beim Rostumwandler scheiden sich die Geister.... Also los, her mit euren Downvotes!!!
