#(Edited) Help with drone stopping all the motors after it just "hops" off the ground
636 messages · Page 1 of 1 (latest)
Angle mode is not acro
The drone levels itself
And for beeping to occur, you need a battery plugged in if you don't have an additional beeper
Angle/beeper turns on/off, depending on the position of your aux 2 switch
In Configuration tab there are options regarding the beeper
you want RX_SET and RX_LOSS enabled in both sections (beeper and dshot beacon)
As for angle mode:
Acro (the default state):
Roll/Pitch controls how fast the drone rotates.
Angle:
Roll/Pitch controls the angle of the drone, relative to level (as defined by accelerometer calibration)
Maximum angle can be set somewhere in PID Tuning tab and its sub-tabs
ok so when is angled mode turned on or off?
this basically says: "When AUX2 is between 1400 and 1600, turn Angle ON. Otherwise, leave Angle as it is (OFF)."
Angle mode is enabled when your aux 2 is in the middle position
(Edited) Help with drone stopping all the motors after it just "hops" off the ground
Yo GGManiack, i now have a trouble where when i start pushing up the throttle and when it just starts going off the ground it just stops spinning all motors and lands back down
help
all the mototrs are spinning in it's intended way
@hushed onyx
sounds like runaway protection
ok
which means that one of these is wrong:
Motor order
Motor directions
Board alignment
wdym facing the other way
Point the drone's camera at the screen
And then click Reset Z axis
that way the yaw should realign
like the little arrow on the board is facing to the back of the drone
ill try that
now
oh ok
if you know the board is 180° wrong
then let's do that first
in Configuration tab, you'll find Board Alignment
there is a value called Yaw Degrees
add 180 to whatever is in there
ok
so if there was 0, it would be 180.
If there was 90, it would be 270
ok done, it was 0 so i added 180 and then saved and reeboted
now in Setup tab
there is a 3d model of the drone
which rotates in the same directions as the real thing
so if you yaw the drone by 90°, the 3d drone should also yaw by 90° (ignore absolute yaw, the drone has no idea where your LCD is, you can click Reset Z to zero it)
yep
the when i til the drone toward my laptop screen the drone tilts toward me, is that right?
depends on the yaw..
you can see the arrow on the drone
arrow points forward on the drone
okay, quick trick
set the drone so that its camera is pointing at ("seeing") the screen
and then click Reset Z
now both drones should be pointing in the same direction
and they should move exactly identically
yes now they move exactly identically
okie
ideally from a top-back angle
like if you were a camera in a racing game behind a car😄
tag me when you do
send a screenshot of BF Motors tab
Is this your final build?
The motor wires dangling around are a bit sketchy
around the motors?
Shorter, directly to the esc
yeah ill find some tape or smn'
the motor direction in BF is wrong tho
when i flew i t i checked and they were correct
oh ok
First, a sanity check
On all of your props, the top edge should be blunt, and the bottom edge should be sharp.
can you help me fixing them please?
I'm still worried that the sharp edges could cut the wire insulation, which leads to the motor wire touching the conductive frame...
ill wrap the whole thing in electrical tape, will that e enough?
?
@gilded socket I'm primarily worried about the front-right prop btw
but it might be just lighting..
re: ^
just the top front right one needs to go the other way
ive done that
now
why, is it the orientation?
yes
btw - do you know what you get when you flip a CW prop upside down?
nope
what happens to the prop
you have a CW prop
and you flip it upside down
I need you to think xD
to chase out a common misconception 😄
does it do reverse thrust?
nope
to get reverse thrust, it would have to become a CCW prop
which it can't become
when you flip a CW prop upside down
you get a really shitty CW prop
that is better at making noise than thrust
Basically means you need to swap the prop
what?
haven't gotten to swap prop stuff yet xD
send a new pic of the drone
🤦♂️🤦♂️🤦♂️
so that I can sanity check all of the props 😄
okie
Ah fuck I was stupid
For some reason I thought an upside down cw prop would get a ccw
haha yup that's the common misconception
upside down CW = still CW, just bad
Idk I think I flipped a prop once and somehow I felt like it went from cw to ccw
it will have very little thrust
grab a spare prop 😄
and flip it upside down on the table
see how the shape changes
thank you.. for all of the... 15 pixels in total
yeah so basically you have it set up for reverse prop direction
ok, how do i fix that?
isn't that correct?
in BF meanwhile, you have htis
see how all of the arrows are opposite?
compared to the real drone?
tick "Motor direction is reversed"
and then save
yep
done, that looks more right
okay, now, take the props off
on the right side of Motors tab, you can spin up each motor
after you tick the "I'm not an idiot and I took off the props" thingy
I am going to throw this keyboard against the wall really really hard if it misses one more keystroke
what if you are a idiot ??? xD
Then keep the props on and lose your fingers
Okay, tick the "Betaflight team and whoever is helping you is not responsible for harm you cause to yourself with your idiocy, but please take off the props anyway" checkbox @gilded socket
then, spin up each motor INDIVIDUALLY
you need battery for this obviously
you want to check that when you spin up motor #1, motor #1 is the one that physically spins up (refer to the diagram to see the motor positions)
ok
-# I have to admit, I tested motor direction with props on on a 65mm whoop already
okay a whoop is a very different story
wtf, i put the batterry in and i got disconnected
fun
🤦♂️🤦♂️🤦♂️
I also did it on a 5" more or less, but it was accidentally while I was flying
dw it worked
wait which thing do i click on, reorder mototrs or the direction?
I have only managed to take a chunk of flesh off of my finger while loosening props
a friend of mine accidentally full throttled his drone right as he was bending over to pick it up... by a prop.
he has permanent scars on his hand 🙂
neither
on the right side of Motors tab, there are the sliders
and there is the checkbox under them
Prearm saves fingers...
yeah they're in the correct position
and all spin in the correct directions?
I also have scars because of it, could be permanent too
Was 2-3 months ago
oof
yes
heal well 🙂 @slim sky
@hushed onyx
@gilded socket well, assuming you didn't lie to me anywhere, it should be flyable
Well, at least I can show people now how serious they should take safety with a 5"
as long as you reinstall the props correctly
ok ill go try fly it now
I've seen so many bloody pics over the years
Don't cut off your fingers
Always at any time
it is faster than you expect
even this basic 3S setup will be plenty too fast for a newbie xD
Disarming saves both you but also the quad
0 to Mach Jesus faster than you can blink.
Acceleration from drones is crazy
Exactly.
90MPH is 40m/s.
That is 10 metres in quarter of a second.
The time it needs to get to the top speed is irrelevant as its accelerating so fast
(Which, off topic, is why VR headsets as FPV goggles is a dumb idea. 200ms latency means that 90mph drone covers about 8 metres before you get to see it happen.)
It's always a good idea to not take off a few steps away from your drone, especially when flying it for the first time @gilded socket
Better to go a couple meters away
My 5" cartwheeled over 100 metres across a flat grass field once.
All I did was clipped the deck in a sweeping turn 'cos I banked a smidge too far over.
If it had come my way, there would have been blood.
the long lack of response is worrying 
He's either having fun or on his way to a hospital
???
o get it now
Seems like he survived
i id
did
but i crashed it like 15 times before my batterry dies, my second batterry connector i need to resoldier it
i think the first option
thankfully
Where were you flying?
like i have a small field near my house
but the drone is so fricking fast it's hard to control
plus i'm flying los
not like flying LOS makes ny difference but still
Anyways thats a lot to specifically @gilded socket he's the man
@hushed onyx
wrong ping ,ol
i don't have goggles yet
Oof
angle tho
Fpv is easier than Los imo
The entire company? Damn you're loaded
Why would you buy an fpv drone before buying the goggles
do you have any suggestions on like some cheap googles that don;t have thier camera quality crap af
??
🤦♂️🤦♂️🤦♂️
my parents got me them for my bday so don'y judge, all of us are newbies
Cheapest worth having Ev800d, skyzone cobra x are great but more expensive, you can also look for some used goggles and ask in this server if they are worth buying
?
the skyzone cobra's are abit too expensive, but the ev800D are good, are they digital or analog, and if they are analoug how good is the quality?
Analog, bad
Cobras are analog but better
I haven't tried the Ev800d personally, but you can ask someone who has them about the quality
what about these?
why not, in my currency it's not expensive
in usd it's around 75 ish
Yah but they are probably even worse
I also found these on a facebook community
Those would be better, but how much do they want for it?
Hmm
I think that's not too bad
Especially because they have the tbs fusion module
Just make sure they don't have bad sun spots
wdym by that?
what is that?
If you leave the goggles out in the sun, it can damage the displays
oh ok
Makes some green spots on the display
?
A good analog module
i see
oh i see
ill text them and see
wait what about the transmitter?
do i have to buy it myself?
i have a cam but not sure if there is a transmitter
i built the camera myself?
What is it connected to
no
The drone
yes
Uhh idk if you put a vtx in it or not
no
Wdym by that
yeah it doesnt have a transmitter
Do you have a picture of the open drone?
i havn't put the camera in yet
will a picture of just the camera and everything that was included in the camera thing allright?
?
So I can see the electronics
Hello
what do you think about this
ill take a picture soon
@hushed onyx what do you think of the goggles and the VTX?
vtx seems overpriced, is that USD?
what goggles (all fatshark HD shit looks the same lol) and what price?
no it's not, it's nzd
so about 20 usdt
150 usdt
ah, then the price is alright, but still not a great VTX for a 5"
and what model are they?
i'm not sure, that's all the informatino they give, i can can ask them though
why not?
it's a whoop VTX 😄 wrong mounting pattern to start with, u.FL is also not great on 5"
are any of these good for mine?
just divide the price by 2 to approximataly get USD
well, ig those are worse even xD 350mW isn't a lot for a 5"
the other one is 400mW iirc
figuring out an antenna setup on a 5" with ufl is difficult
mmcx is easier
90° mmcx antennas are made in 5"-ideal lengths
and have a lot less of a chance of coming unplugged in flight
heck, TBS had to invent a screwdown plate do prevent ufls from flying apart
i think i found something decent
?
yeah this one is decent
I personally don't like it that much because it requires 5V power, but it performs fine
my output for my camera and transmitter have 5v
the problem isn't with the availability of 5V, the problem is with the fact that VTX's are very power hungry
oh
and I dislike putting too much load on FC 5V
so how much will it cut my battery by?
not the issue xD
seconds, at most, lol
the issue is the current capability of the FC's 5V regulator
what does that mean?
The FC takes battery voltage and steps it down to 5V, for itself and external electronics (receiver, camera, etc)
also will it be compatible with the goggles and fc
that step down circuitry has a limit as to how much current can flow through it
i have an esc that steps down to 5v
you don't want to use ESC 5V, that shit is vile..
noisy as hell
how old are your ESCs, jesus
5V on ESCs hasn't been a thing for a very long time
at least in drones
I can't recall what your setup has lol
but anyway
what FC have you got?
no it goes from battery to esc which steps down to 5V which then goes to FC
jesus christ
I'll be really surprised if you ever get watchable video...
there's a reason that style of build was abandoned in like 2016
ESC 5V is extremely noisy
wdym it's noisy?
not sure how to explain that from scratch, what exactly do you not understand about it?
is it like the radio will be noisy, like in photography if you tur your sensitiviy(ISO) up it begins to capture extra "noise" (light)
is it like that but only with the vtx transmittion
it is a similar kind of noise but much more varied and rough
the ESC does a lot of very harsh things with a lot of electrical power
that causes a lot of random electrical fields to pop up
if the 5V regulator is on the ESC, it can very easily end up being affected by that
so the 5V may be 5V on average
i do have a step down convertor
but if you look at the graph of the voltage, it's a mess
That's why 5V regulators very quickly transitioned onto the FC's, which don't have to deal with a lot of power
so, what FC have you got?
That thing definitely has its own 5V regulator
actually it has a 5V and 9V regulator
Are you not using the ESC that's meant to be used with this board?
I am hella confused now 😄
why are you using another ESC with a 5V regulator?
i am using the thing in tio left
*top
You have a FC and 4in1 ESC
The 4in1 ESC doesn't step down 5V, the FC does it
it doesn't?
when i checked the documentation for the helios it said that it did
?helios?
ooh
BLHeli_S is an ESC firmware that this runs
ooff
the ESC hardware is designed to run BLHeli_S firmware
that's what makes it a BLHeli_S ESC
but anyway
oh i see
In your case, it's the FC that makes 5V
Its 5V regulator can do 2.5A... lemme do some math
Do you have any decorative LEDs on the drone?
nope
I'm not asking, it's literally in the specs 😄
The VTX will draw up to 0.8A roughly
so it's kinda fine
camera is like 0.3A
the FC itself like 0.2A
so is this still applicable?
nope
from your description, it sounded like you had individual ESCs with 5V regs on them 😄
oh, i didn't realise
thanks for explaining
Your FC has its own 5V regulator so in terms of noise it should be okay
The 5V regulator is beefy enough
so even that should be okay
so what harm can the fact that the vtx is taking from the fc cause?
Some cheaper FC's use a 1.5A regulator, in which case it wouldn't be okay
The VTX draws up to 0.8A
what about mine?
The Speedybee TX800 VTX draws up to 0.8A from the 5V line.
Your FC can produce a total of 2.5A.
Receiver = 0.2A, Camera = 0.3A, FC itself = 0.2A usually
those are mostly peak numbers, not necessarily sustained
VTX (0.8A) + RX (0.2A) + Camera (0.3A) + FC (0.2A) = 1.5A
so you should have 1A to spare, which should be okay
on some shittier FC's which have a 1.5A 5V regulator, it wouldn't be okay
that's one of the reasons why I was worried
oh ok
anyway, the TX800 is generally well regarded
last thing all the stuff are compatible with each other (goggles-VTX)(VTX-FC)
just get an antenna with a 90° MMCX connector for the vtx
yeah
I'm not sure how good of a value those goggles are
the module in them is good, the goggles themselves, idk
did you measure your IPD?
to see if the goggles will even work with your eyes xD
what does IPD mean?
inter-pupillary distance
why?
distance between eye pupils
something like this?
that's an adapter not an antenna xD
would that be a problem?
you can buy an antenna that directly has the right connector
with slimline goggles like those fatsharks, yes
you have to adjust the screens to match your IPD
and the adjustment range is limited
any of these?
those are all adapters, not antennas xD
ill probably go check it out before i'll buy them
for me, none of those goggles work, because my IPD is just way too wide (bigass head)
🤦♂️
should be fine but again ill have a look before ill buy them
these kinds of antennas exist
these are antennas any of these?
the selection on that site is impressively tragic
one thing to note
antenna compatibility
RHCP x LHCP (signal polarisation)
you need the same kind on the goggles and vtx
oh
do you have enough info to determine if my goggles are compatible with the vtx?
?
the VTX is not the problem
it's just about antennas
a RHCP antenna sends a RHCP signal (RHCP = right hand circular polarised)
essentially, RHCP means that the signal has a right-hand spin on it
and, to receive a RHCP signal properly, you need a RHCP antenna
a LHCP antenna will almost entirely reject RHCP signal
Analog FPV is mostly RHCP
but it's up to the owner
oh
so idk what antenna is on the goggles
it'S not written in the post
anyway, back to the shop and VTX antenna...
they don't have any RHCP MMCX antennas
correction
no nvm
none that I can see
only LHCP
oh
God dammit that shop is cursed.
Yeah you should
So, for 90° MMCX antennas, Kiwi quads only has LHCP ones.
okie i will
so i'll ask about the antenna
but should i order the vtx?
where is that from?
From Speedybee's website
not rlly
should i buy from there?
nono
I'm sending it to show you what's in the package of the TX800
The TX800 comes with
- a small linear (non RHCP/LHCP) antenna, which you could use to get started (veeery short range though)
- a MMCX to SMA adapter
so you can use a SMA antenna as well
(warning, SMA and RP-SMA are different connectors!)

these are just examples.. there are more on the website
I'm not rating them, figure out which one you like based on price and size...
figure out where the VTX will fit in your drone
and from that figure out how the VTX + adapter + antenna will fit
@hushed onyx should i ask the guy who's selling the goggles any questions?
i there's like a little space under the reciever which i'm not sure that enogh, but i also do not kn ow where to put the power cable
i know
nope
That space Is usually for the rx I think

It looks like your stack is 180° rotated
The upper side with the metal parts is the front
🤦♂️
The arrow should point upwards to the metal part
d o you know how i can position my camera?
I'll change that tommorow
@hushed onyx i found out the antenne type, its the rhcp antenna on the goggles
Also guys do you think i will be able to fit this?
and where?
og god I forgot that you have that massive shitting receiver
lol
Could you just like... switch to ELRS? 
Just scrolled up.
What the shitfuck is that? The Nineties called and want their Rx back.
I genuinely wouldn't feel safe using FlySky on a quad of that size.
and that's the second one I'm dealing with in parallel today
wait what's elrs again?
is that a transmitter or smn?
wait does that mean i also have to buy another controller?
yes it is a transmitter
A better radio link
You'd need another controller or an external module
🤦♂️🤦♂️🤦♂️
like what do i do?
i'm allready broke from buying the goggles, the drone itself
also
what does this mean
?
TBS Fusion is the video receiver module that goes on the goggles. It combines two signals, from two different antennas that you attach to it. The regular antennas are omni antennas that receive signal from basically all directions. A patch antenna has a smaller "field of view" essentially. It can receive signals from much farther away, but only in a specific direction. RHCP stands for "right-hand circular polarisation", it's the type of polarisation that the antenna uses. This is the typical polarisation used for analog video on anything bigger than a tinywhoop (they use linear polarisation antennas because they can be much lighter and smaller)
i'm just not sure how i can squish a camera and vtx onto the drone lol
^
Is the battery wire coming out the front of the drone? If so:
Rotate the ESC 90 degrees (you'll have to update the motor order in Betaflight after that) so that the battery plug comes out the side. Maybe put some tape along the edge of the frame too so it doesn't cut the wires.
Mount the camera where the battery plug used to go.
If the frame is tall enough, mount the VTX on top of the flight controller stack
yeah that was a temorary solution
does it say how tall the vtx is?
if not then what?
No that shows the outer dimensions and the hole mounting pattern
then how do i know how tall it is
it also says that it comes with an antenna but i have no idea what kind it is
mach 5
frane
the fc itself is 3.5 by 3.5
the hight will fit but whats are the length and width?
^
It says it comes with this one.
https://www.speedybee.com/speedy-bee-5-8-ghz-antenna-v2/
oh ok
No what is the brand and model of flight controller?
have no idea but this is what came with it
Looks like it's this one
http://dakefpv.com/pd.jsp?id=38
yeah
nope
not sure what is then
do you need the dimension or smn?
do you know the length and width of the vtx?
Do you have a link to the frame?
Yeah. But also if it looks like there's plenty of space above the FC then it'll probably fit
The other option is to move the FlySky receiver somewhere else and mount the VTX where you have the receiver right now
I think, anyway. Assuming you've got mounting holes there
do you know how i should mount the camera though?
3D printed mount, if you've got access to one
Depending on the camera and the mounting options the frame provides sometimes you can get pre-designed ones
Or sometimes there'll be side plates that come with the frame that are meant to hold the camera in place
It really depends on what your frame came with
i have this mount:
There's no picture?
there you go
Oh yeah that's standard. I meant moreso the mounting options provided by the drone's frame itself
wait so just cheking
do i have to buy an antenne for the vtx ?
Only if you choose not to get one bundled with the VTX
Huh?
this thing
ow well ill buy the vtx and goggles and see what else i need
Ah. Can you send the specific link you're buying the VTX from?
yeah
The reviews say it comes with an antenna, so it's probably best to hold off on buying an antenna for the VTX until it arrives and you can confirm whether it comes with one or not
it comes with a tiny linear antenna which isn't exactly useful when the goggles have a RHCP antenna...
Oh yeah definitely get a proper one lol
Like.. for initial setup and some short range flying mayyyybe
