I have this now😁

#

I can put some IPA on a cotton ear stick? And just brush it over.

lucid sun
#

Is that one on the right oke, or should I move it more to the center of the pad

dusk wadi
#

I'd say that's perfectly ok, but you can touch it up to match the others

lucid sun
#

Okee! Now its time for the fc 😮

#

I just realised watercoating is gonna be a bitch

#

The motorshield are 3m'd onto the frame

#

Does it matter what I do first? Receiver or vtx

lucid sun
lucid sun
#

Tx to r2

#

Rx to t2

dusk wadi
#

Correct

lucid sun
#

Can I heatshrink the antenna's?

dusk wadi
#

Not sure what part you want to heatshrink but most likely yes

lucid sun
#

The white ends of the tbar

#

For the one under the motorarm

#

And for the front I put a ziptie ontop of the T connection, should be ok

dusk wadi
#

Yeah sure

lucid sun
#

The standard tpu doesn't fit.😁

lucid sun
#

Where does the green black wire go? @surreal meteor

surreal meteor
#

joystick cable

#

for the cam

#

idk if caddx is finally including a joystic or button board with their cams

#

if trhey do its so you can make changes in the cameras settings

#

like turning off the internal OSD etc

lucid sun
#

This is not necessary right

#

It comes with the button board

#

Joystick actually

surreal meteor
#

not a necessity but if it has a camera own OSD it can be overlapped by the betaflight osd and annoying

#

youll have to see once u power it up

lucid sun
#

Oke

#

King dihler

#

🤙😁

#

Last thing

#

Vtx should go with heatshrink up?

surreal meteor
#

this one has a heatsink around it

#

not really necessary

surreal meteor
# lucid sun https://youtu.be/M3dd850WyBM

btw for this: hes talkin about how the cable is too thin but disregards that the ESCs are powered by traces on the board that can reliably send 30A and more through them

#

just to put that advice in perspective

lucid sun
#

Tramp (vtx) goes to VTX (speedybee f405)

Gnd to G
9V to 9V

#

Right?

surreal meteor
#

9V?

#

for the cam right?

#

oh i thought this was a rush tank solo for a second lmfao

lucid sun
#

Haha

surreal meteor
#

they have the same heatsink

lucid sun
#

I can put 24 v in straight from battery😁

surreal meteor
#

video goes to vtx, gnd to gnd, 7-36V to vbat or 9V your choice, tramp goes to a TX pad of your FC

#

tramp is there to have your FC control youur VTX so you can change channels through smartaudio/tramp

#

since the 9V is so neatly there id use that

lucid sun
#

From the top: the video / gnd/ and 5v out have a standard connector to attach to camera

surreal meteor
#

video on the VTX is for video input into the VTX

lucid sun
#

Oke yeah

surreal meteor
#

since you are routing your camera through the FC you need to take that signal which comes out on the VTX pad and sent that there

lucid sun
#

Vbat is 24 volts?

surreal meteor
#

vbat is whatever your battery is at

#

direct passthroguh

lucid sun
#

But battery is fluctuating alot more then the 9V pad I assume

surreal meteor
#

it is but the VTX has its own vreg on board

lucid sun
surreal meteor
#

9V will be cleaner tho

surreal meteor
lucid sun
surreal meteor
lucid sun
#

So i'll not use VTX. But t1?

surreal meteor
#

you need to get the video to the VTX

#

those 3 pads is where oyu r camera goes on

#

this is what u use for the VTX

lucid sun
#

I know but this VTX can ask like 2.5W

surreal meteor
lucid sun
#

10

#

My bad

surreal meteor
lucid sun
#

Im used to calculating in kw

surreal meteor
#

in Ampere

#

277mA

#

not much current

lucid sun
#

Jup

surreal meteor
#

if u use vbat itll ask even less current

#

cuz higher voltage

surreal meteor
#

you are not plugging the cam into the VTX are you

#

i mean you can if you do not want OSD

lucid sun
surreal meteor
#

nope dont do that

#

this bypasses the FC

#

if you want onscreen display you wanna route the cam to the FC

lucid sun
#

Ah

surreal meteor
#

and oyu want OSD

#

to see the battery voltage and so on

lucid sun
#

I hope the wire is long enough

surreal meteor
#

wdym it doesnt have to be long

lucid sun
#

So for vtx I dont use the 5v out now

surreal meteor
#

u wont use it

#

no need

#

unless the 5V vreg on your FC dies but then u got other problems

lucid sun
#

Oke cool

#

And I connect both vtx grounds to 1 gnd on fc

surreal meteor
#

no

#

just one is enough

lucid sun
#

Does it hurt?

surreal meteor
#

its unnecessary

#

makes it easier to build

#

way too much hassle trying to put 2 wires on one small pad

lucid sun
#

They always told me it will act as an antenna

surreal meteor
#

wa

lucid sun
#

Ok

#

Nvm

#

Thanks alot for your help

surreal meteor
#

like i said

lucid sun
#

I'll continue tomorrow I want to nail the vtx

#

Yes

surreal meteor
#

or use vbat

#

or BAT as it is labelled on the FC

#

and i would use these 4

lucid sun
#

Thanks man, I see now. The connector trew me off

Let's make vote for when I sleep:

Vbat or 9V for foxeer Reaper vtx 2.5W

surreal meteor
wary anchor
#

9v is generally better filtered

surreal meteor
#

i mean itll double filter so yeah

#

and stop worrying about that the cables could be too thin for the power going through them

#

its fine

#

the traces on the boards are even thinner at times

lucid sun
#

This mount is for mounting on airplanes and such right?

dusk wadi
#

I've used that in a frame too, but in your case that's useless and won't work

lucid sun
#

For the big vtx

#

What place, im thinking about C

#

A could be possible maybe

dusk wadi
#

Think of how it affects taking the top plate off

lucid sun
#

I will mount it the the tpu part of C, or is this not sturdy enough

dusk wadi
#

Either you need to be able to easily able to unplug it

lucid sun
dusk wadi
#

Eh, should be fine

lucid sun
#

Heatshrink canals should be on the touching mounting surface I assume

#

Like this

lucid sun
#

I find it weird, it comes with mounting screw holes. But it doesn't fit anywhere. Maybe it's because my frame is kinda designed for digital

dusk wadi
#

The mounting holes are 20*20 but actually meant to mount a fan

lucid sun
#

Ah that makes sence

#

It will overheat without?

dusk wadi
#

Nah, being mounted on a drone provides it with all the airflow it needs

#

Mostly an issue in planes and stuff

lucid sun
# lucid sun For the big vtx

B would probably be the best spot, for cooling🤔 and no noise from the battery.

But it doesn't fit in its length, I would have to rotate it 90° making the outputs coming outside the frame😐

lucid sun
#

Makes sense

lucid sun
#

Lemme try something, i'll send some photo's for an idea.

lucid sun
#

So the cap is a bit in the way

#

Does it matter if the outside of the capacitor is hitting both the + and - of the solders blobs

#

And, If I elevate the vtx with the
thickness of the arm it can fit.

dusk wadi
#

Check for continuity

lucid sun
#

Oke

#

For my gps this is the way?

#

M8q-5883

dusk wadi
#

yea

lucid sun
#

What do I do with the ground I don't use. Cut it off short?

lucid sun
dusk wadi
#

you can remove the pin from the plug

lucid sun
#

Super

lucid sun
#

Oke for scl sda

#

I assume not like this

#

But:

#

180° ?

dusk wadi
#

no first one was good

lucid sun
#

Oh

#

Oke🤞

dusk wadi
#

tbh you might not wanna even use the compass, I've heard it doesn't help/even makes things worse on betaflight rth

#

but you can disable it in fw after too

#

so there's no harm in wiring it

lucid sun
#

Actually

#

And I can always just unplug the connector from gps without the wires acting like weird antenna's?

#

So now I just wire the camera, and then im done??

dusk wadi
lucid sun
#

My only concern is that I didn't plug the fc to esc plug in good. But I don't think it goes any further

#

It has connection gnd to gnd

dusk wadi
#

should be fine then

lucid sun
surreal meteor
#

you know how antennas have a big hex nut looking part that screws on?

#

thats what the black print is supposed to go on

#

to make it easier to tighten it by hand

dusk wadi
# lucid sun

the rings and nut go on the outside to tighten the plug onto the 3d print

lucid sun
#

Oke so both rings on the outside

dusk wadi
#

eh tbh idk for sure

lucid sun
surreal meteor
#

the connector nut is a lil small isnt it

lucid sun
#

I couldn't find this

surreal meteor
#

They work quite well too

lucid sun
#

1 ring has like little teeth, the other is pre-torqued or whatever

lucid sun
dusk wadi
#

teeth are made to bite into the plastic

#

spring applies pressure

lucid sun
#

I can imagine

#

But probably springwasher on the inside of the frame. And the teeth pointing towards tpu on the outside? And then the nut to secure

surreal meteor
#

thats how i would do it but i dont use that style pigtail

lucid sun
#

I didn't choose this product

#

😜

surreal meteor
#

me neither lmfao

lucid sun
#

But connection is only the middle part right

surreal meteor
#

and the outside

lucid sun
#

Aswell

surreal meteor
#

ye

lucid sun
#

Oke so it should matter

surreal meteor
#

which is why it shouldnt touch the carbon

lucid sun
#

I see

#

@wary anchor you know this rings stuff?

dusk wadi
surreal meteor
#

all that matters is that its tight enough to not rattle around

#

and ideally not unscrew itself

#

but thats what you got the 2 washers for

lucid sun
#

Oke:)

#

Using pliers to tighten it is a no go then.

surreal meteor
#

just be careful not to mess up the threads and not to screw throguh the tpu

#

but use some force aka pliers

#

or a socket if u got one

lucid sun
#

👌

surreal meteor
#

thats a very long antenna for a 5" lol

lucid sun
#

I didn't pick this

#

🤣 haha, no but I need long range. Im gonna fly over water and such

lucid sun
#

Bottom of the drone of top plate

surreal meteor
lucid sun
#

Or I can just go over vtx

#

Squish it into place

surreal meteor
#

what is below the vtx?

lucid sun
#

Motor arm

surreal meteor
#

does the vtx not fit on the bottom?

lucid sun
#

No, only if I elevate it 0.5 cm to the level of motor arm

#

Big ass unit

surreal meteor
#

ye just put the strap above the vtx then lol

#

i presume youll zip tie the vtx to the 3D print?

dusk wadi
#

there should be slots in the top plate

#

for the strap

surreal meteor
#

not really

lucid sun
dusk wadi
#

oof

surreal meteor
#

nothin against putting the strap around the top plate

dusk wadi
#

does that 3d print just friction fit on the standoffs ?

lucid sun
#

Yes

dusk wadi
#

then yeah just leave enough space to slide the strap through

surreal meteor
#

wait do you have 1 or 2 straps

lucid sun
#

2

#

But I have a big ass unit battery

surreal meteor
#

ye then 1 back one above FC

lucid sun
#

And to mount the vtx to tpu I was thinking just zipties with heatshrink around them?

dusk wadi
#

you don't need to put heatshrink on the zip ties

lucid sun
#

So it will not slide out🤔

#

I have no idea about the forces on this thing

#

But 200 km is fast

dusk wadi
#

do you have a battery pad ?

lucid sun
#

Yes

dusk wadi
#

oh wait you meant the vtx

#

yeah no that won't slide out if you tighten it against tpu

lucid sun
#

Oki👌

#

And last thing the sma to mmcx cable

#

You need to watch out with bending this?

surreal meteor
#

dont kink it

#

just coil it or something

lucid sun
#

Coil

#

I could feed it through this little spacing

#

But this is gonna get squashed by the vtx zip ties

#

So better down the bottom?

lucid sun
#

But what do you mean with coil it

dusk wadi
#

just run the excess length in loops

dusk wadi
#

Tuck it in and zip tie it to the bottom plate

lucid sun
#

This doesn't matter for noise and such?

#

I will push it more down into the cap

#

For room for the straps

dusk wadi
#

if that starts vibrating maybe

lucid sun
#

So it's better if it's just pushed onto the cap, doesn't matter if it actually touches it

#

Or should I heatshrink the cap or something

dusk wadi
#

nah the outside of the cap isn't conductive or anything

lucid sun
#

Oke great

#

To take of the top plate all I have to do is cut 1 zip tie

dusk wadi
#

unacceptable 😁

lucid sun
#

Exactly

#

It hurts

#

😁

#

Last steps, for testing on computer it's better to keep this of? For pressing buttons or anything?

#

And the nuts on the stack you can screw solidly handtight (by hand)

dusk wadi
lucid sun
#

😏

#

If someone can guide me through it in like 1h, Lets see!🤣

#

Anything I should check with multimeter? Apart from Continuity at the battery leads?

wary anchor
dusk wadi
#

visual checks and triple checking your wiring, check back on wiring diagrams and such

lucid sun
#

Does it matter if the motor wires are hitting the fc

lucid sun
#

I hope not

#

@surreal meteor you know this stuff☺️

smoky brook
#

It's only bad if it touches the gyro

surreal meteor
#

if u can try to get em to not do that

smoky brook
#

but it's not really ideal anyway

lucid sun
#

Mhh oke

#

extra zipties

#

Thanks

#

Frame is pretty tensioned when screwed together

#

But carbon composites can bend

surreal meteor
#

that dont look right

#

top plate isnt supposed to bend in an S is it?

#

are you sure you didnt accidentally switch up the taller and shorter standoffs?

lucid sun
#

Im pretty sure

#

The difference is 5mm

#

In standoff

#

Now when tensioned it's alright

#

I think it's because the vtx tieraps/tyraps and the battery strap is kind of pushing things up

smoky brook
#

That still does not look great

lucid sun
#

Should I add rings?

#

Washers

surreal meteor
#

something is defo not right there

#

its like there is a plate missing in the back that is supposed to hold it up

#

what frame is this

lucid sun
#

Maybe it's compressing the tpu mount

surreal meteor
#

nad thats slid on the standoff

lucid sun
#

iFlight Titan DC5 v1.4

#

It's like this🤔

surreal meteor
#

@smoky brook am i seeing things or is it bending on the product shot as well?

#

thats the only sideview they give you oin the website

smoky brook
#

doesn't look bent to me

surreal meteor
#

i think it is but not as strongly

lucid sun
#

Is it possible I bend it

smoky brook
#

No

lucid sun
#

By tightening 1 screw before the side slabs were correctly in

#

I mean it's carbon

#

Should bend back

surreal meteor
#

it will bend back

#

but the standoffs arent making an even plane on top

#

which is not right

#

by the way the frame is made these 4 standoffs should be the same length can you check that?

lucid sun
lucid sun
surreal meteor
#

i hope its nto a manufacturing fault

#

or packaging error

#

idk but something doesnt add up here

lucid sun
#

Oke took it all off

#

Plate is straight

#

Wtf

#

Why

#

That's why

#

Now what

lucid sun
dusk wadi
#

Wth

#

Are the others not recessed like this?

lucid sun
#

No

#

Well the one opposite

#

But the front no

#

Or back

#

But ok whatever, washers?

dusk wadi
#

I'd take off all standoffs and see what lengths they are

lucid sun
#

I don't have:)

#

The standoff are the same

#

Woah look what I found 😏

dusk wadi
#

a bit scuffed ngl

lucid sun
#

I have to sand them a little bit

#

Lol

lucid sun
dusk wadi
#

yes absolutely

lucid sun
#

But wait

#

Maybe

#

I know

dusk wadi
#

ah uhm

#

did you maybe put those pieces upside down

lucid sun
#

That was what I was thinking

#

Mhh..

#

So this means taking it all apart again

#

No way

lucid sun
#

As straight as a pancake

#

Finished building my drone, need BF help

#

Can someone guide me through betaflight

lucid sun
#

If I just want to connect it and shoot it up once hover and go back down. How long will it take me to set it up?

#

No gps rth or anything

surreal meteor
#

shouldnt take long if you remember which UART you soldered what to

dusk wadi
#

you need to flash the receiver (or set the bind phrase through webui), do your ports, make sure the motor directions are correct, check channel map, assign your modes and it should takeoff

lucid sun
#

Alrighty

#

So like 1h

dusk wadi
#

I might be forgetting something

surreal meteor
#

chekc motor mapping too

lucid sun
#

you need to flash the receiver (or set the bind phrase through webui) which you recommend

surreal meteor
#

which ever is needed

#

if its already on the right firmware use webui otherwise flash reciever

dusk wadi
#

It's already on 3.0 so you can just set the bind phrase, but iirc there was a fix to get both rssi values in telemetry

#

So might be worth flashing at least at some point if you care

surreal meteor
#

webui is the faster route for just getting it done basically

dusk wadi
#

Yep

lucid sun
#

I don't understand but nothing you can do about it I guess🤣

#

In downloading bf config and bf now

surreal meteor
#

if i wqere you id spend some time doing some research on everything

lucid sun
#

So better not rush it in 1h to just get it to spin the motors

surreal meteor
#

and also whatever you do DO NOT HIT THE "RESET TO DEFUALTS" BUTTON

lucid sun
#

oke o.o

#

I saw some post coming around, someone who did that.

surreal meteor
#

ye dont do it

#

that button resets everything including flight controller specific settings

#

leading to you usually having to reflash the FC

lucid sun
#

Pre-release is ok?

dusk wadi
#

You don't have to download that

#

Just the configurator

surreal meteor
dusk wadi
#

But yes you'll want 4.4 for the better rth

#

So get the 10.9 configurator

lucid sun
#

Oke got it

lucid sun
#

4.4 is just the "OS"

smoky brook
#

4.4 is the OS which is flashed to the flight controller from the configurator

surreal meteor
#

or at least the beginning

#

it explains that

#

valid for 4.4 as well

lucid sun
#

I also saw something about overheating your vtx when on cable

#

or is this only when you also have the battery plugged iun

surreal meteor
lucid sun
#

even when its on 9v instead of vbat

surreal meteor
#

ye

lucid sun
#

cool

surreal meteor
#

the 9V rail isnt powered by 5V usb

#

lol

lucid sun
#

so I should be ok plugging it in:)

#

maybe 9v became 5v

#

;P

#

I didn't know I had so many leds

#

Jeez

wary anchor
#

there's the rx and the FC and prolly the VTX

lucid sun
#

the superD actually

#

didn't expect that

#

or the camera

surreal meteor
#

elrs recievers be bright af

lucid sun
#

I like it

#

it illuminates the TPU side panel

wary anchor
surreal meteor
#

ye its really cool

lucid sun
#

He doesn't say to change these sliders in the video, but he has them enabled. Should I enable virtual connection mode

dusk wadi
#

Nah

#

That's to be able to connect to a "virtual" drone in the configurator to access the available settings for demonstration purposes and such

lucid sun
#

you guys flash FC? or like pc if it works it works?

dusk wadi
#

So might as well do it before setting it all up

lucid sun
#

ah oke, I thought 4.4 came later

#

that this was just it's own software

#

will do!

dusk wadi
#

Huh?

#

You have the configurator

#

Which let's you change settings on the flight controller, and flash (read "write software") the fc

#

I'm telling you 4.4 has much better rth so it's worth upgrading to in your case

#

Flashing from a major version to another 4.3 -> 4.4 wipes your configuration

#

So I'm telling you to flash first, and then set it up

lucid sun
#

yeah I get that.

#

I thought speedybee has it's own software also. And it works parallel with BF but you only update BF

#

I understand

#

but..

lucid sun
dusk wadi
#

Where it says release

#

Set that to release candidates

lucid sun
#

My bad, I thought show release candidates did the trick

dusk wadi
#

All good

lucid sun
# dusk wadi All good

When reading through posts like this. I felt like, these kinda things were not gonna happen to me

#

😛

#

so I can skip this now

dusk wadi
#

You can disable the accelerometer in the configuration (?) tab I think

#

Or just calibrate it lol

#

Ah but you're still on 4.3

lucid sun
#

Yeah I have to connect before flashing for backup

surreal meteor
#

thats different

#

apply custom defaults

lucid sun
#

Ok so I apply

#

Just to be sure😏

#

before the name was speedybee now its different

#

still f405 tho

dusk wadi
#

Huh that's weird

#

Eh prolly fine

surreal meteor
#

ye dw bout it

lucid sun
#

It's like im coding a UFO, this is cool

#

eventough I didn't coding shit

wary anchor
lucid sun
dusk wadi
lucid sun
#

dont get me wrong, it's easy.

#

I assume ardupilot is a bitch?

#

😛

dusk wadi
#

Haven't experienced it myself but senko can tell you about it stare

lucid sun
#

loogi also right 😛

#

Addicted to ardu

dusk wadi
#

I, don't think so, ummm_yes was fighting with it the other day

wary anchor
#

hehehehehe

#

hehehehehehehehehehe

#

yes.

#

just a bit

#

a tiny bit

lucid sun
#

xD

#

im kinda confused about ports

#

UART1 is my vtx UART2 is my superD receiver

smoky brook
#

Why are you turning on MSP?

lucid sun
#

UART6 GPS

smoky brook
#

MSP is not a "turn this UART on" toggle.

surreal meteor
lucid sun
surreal meteor
lucid sun
surreal meteor
#

gps is under sensor input

#

if u lookin for that

lucid sun
#

I don't have it connected yet

#

can I already set it up?

surreal meteor
#

ye

lucid sun
#

probably next week

surreal meteor
#

but dont if u wanna hover test it

lucid sun
#

and he said something about the ports resetting everytime, I don't really understand when they will

lucid sun
surreal meteor
#

lol

lucid sun
#

O.o

#

oke:)

surreal meteor
#

idk what the default failsafe is on bf 4.4

dusk wadi
#

Eh, as long as you don't enable rth it shouldn't prevent you from arming without a lock right?

lucid sun
#

I just disabled it for now

surreal meteor
#

ye

lucid sun
#

oke so save and reboot

surreal meteor
#

aye

lucid sun
surreal meteor
#

happens

#

unplug and plug back in

lucid sun
#

again

surreal meteor
#

is the right com port selected

lucid sun
#

yes

#

maybe it's because of this

smoky brook
#

You cannot disable MSP on the USB interface

#

It's grayed out

surreal meteor
#

literally

surreal meteor
lucid sun
#

xD

smoky brook
#

now we just have the big yellow button that says reset settings

#

forgot it was only red in RC builds

surreal meteor
#

the beloved button

lucid sun
# lucid sun again

first it says closed serial succesfully and then this failed to open serial poret

smoky brook
lucid sun

hell yeah

#

i like reworded things a bunch of times to make it as neat as possible

lucid sun
#

you forgot the word betaflight

smoky brook
lucid sun
#

ALL settings to betaflight default

smoky brook
#

It literally does what it says. Zero

#

the absolute minimum config

surreal meteor
#

its already a long warning

lucid sun
#

true

surreal meteor
#

gotta make em concise

smoky brook
#

We'll be doing a proper Betaflight Wiki/Docs re-write, I may mention it there

lucid sun
#

Im proud of you that you prevented so many people ending up with useless drones

surreal meteor
#

its not useless after that

lucid sun
#

now I need help with my error..

#

😛

surreal meteor
#

idk why it is failing

smoky brook
#

tried re-plugging it?

lucid sun
#

yeah 3 times

smoky brook
