Hi, i'm having trouble fixing the osd on my googles (my video transmitter is tbs unify pro 5.8 SMA)
When i go on betaflight it tells me that the osd is activated but the goggles show me no osd i thought initially it was a problem of positionning the information in betaflightbut that did not work.
Thank for i hope your answers.
(Sorry for the text in french in betaflight)

Yeah that's probably it

#

You kinda need to have the vtx connected to the fc to get osd

short gulch
#

yeah i thinks that is it i just need to figure out where to connect it on my fc

lime dune
#

What vtx and what fc?

short gulch
#

fc&esc mamba stack f405 mk2

#

video transmitter tbs unify pro

lime dune
#

Oh yeah you did mention the vtx before lol

#

Okay

short gulch
#

ther is indeed 2 cabes that i didn't connect

hexed pagoda
#

a clear picture of your current wiring would be useful

short gulch
#

yep

hexed pagoda
#

okay so

#

first things first

#

that receiver wiring

#

needs to be redone

#

the FC side connection especially

short gulch
#

yeah it is and the reciever antenna is falling apart

hexed pagoda
#

moving on

#

the camera is completely bypassing the FC, so there is no way for the FC to add OSD

#

I wonder where your VTX is even getting power from

#

but that's a side issue

short gulch
#

directly from the battery

hexed pagoda
#

what wiring diagram did you follow? This is not how you'd normally wire this

short gulch
#

for the vtx ?

hexed pagoda
#

for the FC to VTX connection

lime dune
#

Vid, gnd, 9v and tx3

hexed pagoda
#

that's a bit too cropped @lime dune

#

can't see the camera pads up top 😄

lime dune
short gulch
#

oh i can send you it

lime dune
#

@hexed pagoda

short gulch
#

v

#

the white and green are disconnected right now

hexed pagoda
#

VTX to FC:
7-26V to 9V
GND to GND
5V Out to [nowhere or camera power input]
GND to [nowhere or camera ground]
Video to VID
Audio to nowhere
Data to TX3

#

all of the pads needed by the VTX are next to the FC USB

short gulch
#

i should do to the fc instead of the battery?

hexed pagoda
#

makes it less likely for a voltage spike to kill the VTX

short gulch
#

true

#

ok

hexed pagoda
#

Camera to FC:
Power input (5-whatever V) to [FC 5V or VTX 5V Out]
GND to [FC GND or VTX GND]
Video to CAM

#

make sure that you get your wiring verified before you power it up

short gulch
#

but the vtx supports directly the camera is it better ?

lime dune
hexed pagoda
#

eh

#

VTX 5V output tends to give cleaner video

#

but if your wiring sucks, you might end up with unreliable OSD

#

btw

#

duct tape is not a replacement for electrical tape or heatshrink

short gulch
#

electrical works better ?

#

i have some

hexed pagoda
#

it doesn't fall off as easily and isn't so huge

#

but pls get some heatshrink xD

short gulch
#

yeah that should be better

#

also i got this reciever but it's tearing apart

#

should i change them whith this$

hexed pagoda
#

I'm a bit sad that you didn't ask about what radio system to buy before buying stuff

lime dune
#

Did you like... Solder through the main chip on the receiver?

lime dune
short gulch
hexed pagoda
lime dune
#

What

#

No it won't work

short gulch
#

oh k

lime dune
#

2.4ghz vs 5.8GHz

short gulch
#

oh yeah

short gulch
hexed pagoda
short gulch
#

really

hexed pagoda
#

frsky is a bit of a pain to deal with

short gulch
#

i have this one

hexed pagoda
#

oh no, an R9 module

lime dune
hexed pagoda
#

haha

#

hahah

#

oh, and it's an ACCESS X9D

#

even more of a pain

#

oh well, it can be made to work

#

just sometimes when the firmwares don't come together right, it's a major hassle

#

you can nowadays get a radio with 10x the range for < $200

short gulch
#

oh i already had so much trouble connecting the two

#

ahhhhhhh

#

like is this any suitable for long range

lime dune
#

Absolutely not

#

FrSky has like 1km max

short gulch
#

even whith the module

lime dune
#

500-800m usable

lime dune
hexed pagoda
#

and even then it's kinda ass

#

because it's not really a 1W module

#

FRSKY runs it out of spec

short gulch
#

so if i undertand well frsky is trash

hexed pagoda
#

well

#

the build quality is perfectly adequate

#

it's a perfectly well working radio

#

but the transmission system is a major pain

short gulch
#

i experienced it

hexed pagoda
#

both 2.4 ACCESS and R9

#

FRSKY unfortunately tends to sabotage their radios

#

so that external modules have a hard time

short gulch
#

so i i were to change radios for long range what should i goréà

hexed pagoda
#

well, depends

#

if you want the cheapest solution without getting rid of it

#

then just put an ExpressLRS module into the back of this radio

short gulch
#

could i use like tbs?

hexed pagoda
#

You could use Crossfire to get more range
but why would you when ExpressLRS exists

lime dune
short gulch
#

really?

lime dune
#

Yes

short gulch
#

and for the reciever then

lime dune
#

ELRS

#

Happymodel, Naminmo, Skystars, Radiomaster, and Foxeer

hexed pagoda
#

btw, where are you from @short gulch if I may ask?

short gulch
#

oh

#

i'm swiss

hexed pagoda
#

yeah so 900Mhz systems SUCK in europe

#

lots of interference

short gulch
#

another great news

hexed pagoda
#

due to mobile networks

#

but that's no problem

#

because ExpressLRS exists in 2.4Ghz variant 🙂

#

which is actually the more popular one

short gulch
#

nice

hexed pagoda
#

there are loads of modules to choose from for your radio (with its JR bay)

#

and ExpressLRS receivers are cheap

short gulch
#

but is the vtx suitable for long range too?

lime dune
#

400mw or 800?

#

I can't remember all the tbs ones

hexed pagoda
#

that type comes in 200mW and 800mW variant

lime dune
#

Oh

#

200mW wouldn't be suitable

#

800mW would work

short gulch
#

it's the race edition

lime dune
#

Welp

hexed pagoda
#

200mW then

short gulch
#

in 5.8g

hexed pagoda
#

yeah that's medium range at most

#

with good antennas

short gulch
#

like 1 km

hexed pagoda
#

like, on a plane, with a great directional antenna, you might get pretty far

lime dune
hexed pagoda
#

1km in theory yes, but not with cheapo antennas

short gulch
#

ok i think that's pretty good for a start

short gulch
hexed pagoda
#

goggle antennas are more important

lime dune
#

Quick note... I'm assuming from the redbottoms that it's 4s

#

That won't fly very long for LR

hexed pagoda
short gulch
#

yes 4s

#

but all the component are suitable for 6s i think

hexed pagoda
#

flight time on 4S is a bit of a struggle

#

but okay for a beginner

#

just make sure that you land once it starts to hit 3.5V/cell

short gulch
#

so for long range i would have to take the ELRS and change my drone to 6s and the tbs to a better one right?

hexed pagoda
#

you'll have to test the limits

#

to know what you need to upgrade first

#

btw, good job on actually binding the XM+ to the radio lmao

short gulch
#

oh thanks

hexed pagoda
#

the vast majority of people can't do it without help

short gulch
#

it was a very big struggle

#

and plus

#

my radio came from china

hexed pagoda
#

how many firmwares did you have to screw around with? 😂

short gulch
#

so it wasnt right for europe

hexed pagoda
#

haha, it came in FCC mode not LBT

#

which is a pain to switch on ACCESS

short gulch
#

i had to do a script to change it

hexed pagoda
#

since you need some janky LUA script for it

#

yeahh

#

FRSKY used to refuse to provide you the script

#

someone evetually hacked a script together and they relented

short gulch
#

yeah

lime dune
hexed pagoda
#

btw
LBT is not great for long-range

short gulch
#

i'm nt sure why i didn't come to a server like this when i started

hexed pagoda
#

and really
noone cares about your one little radio not running LBT

#

FCC gets more range because it just screams over other radios

#

instead of shutting up like LBT does

short gulch
#

ok

hexed pagoda
#

you'd have to flash the receiver firmware though

short gulch
#

i did

hexed pagoda
#

which RSSI variant did you flash?

short gulch
#

wait lemme tell you

#

oh k dont have it anymore on my pc

hexed pagoda
#

the receiver firmwares come in 3 variants

short gulch
#

but it was an old version

hexed pagoda
#

no RSSI
RSSI8
RSSI16

#

this sets which channel the receiver reports signal strength on

#

IT IS VERY IMPORTANT TO HAVE IT

short gulch
#

access d16

hexed pagoda
#

that's.. not...

short gulch
#

ummm

hexed pagoda
#

anyway, XM+ doesn't have ACCESS firmware

#

only ACCST

short gulch
#

yes you are right it's the ACCST D16

hexed pagoda
short gulch
#

ummm

#

i not sure which one it was

hexed pagoda
#

well, as long as you flashed one of the RSSI versions, you're fine

#

otherwise you'll have to reflash it

short gulch
#

but since it worked?

hexed pagoda
#

?

#

that's irrelevant

short gulch
#

why would i need to reflash it?

hexed pagoda
#

to get signal strength info

short gulch
#

ooh

hexed pagoda
#

in BF you'll see signal strength on AUX4 (CH8) or AUX12 (CH16)

#

based on the version (RSSI8 or RSSI16)

#

the version without RSSI doesn't send signal strength

#

which is not usable

short gulch
#

so

hexed pagoda
#

that's the radio

short gulch
#

i got this

hexed pagoda
#

we're talking about the receiver

short gulch
#

the reciever i think i did not flash it

hexed pagoda
#

don't lie to me then 😄

hexed pagoda
short gulch
#

i thought it was for the radio

lime dune
#

receiver firmware

hexed pagoda
short gulch
hexed pagoda
#

then you didn't flash the receiver

#

anyway

hexed pagoda
short gulch
hexed pagoda
#

huh

#

that's unusual

#

you managed to get an XM+ with V1 firmware

#

since your radio is on V1 firmware too

#

that means that your XM+ is at least almost 2 years old 😄

short gulch
#

ahh

#

nice more good news

hexed pagoda
#

details really

#

just didn't expect it

#

if you ever need it

#

here are XM+ V1 firmwares

short gulch
#

would it be better if i would to go to newers version?

hexed pagoda
#

I'd love to tell you

#

but idk

#

FRSKY never publicly stated why they made ACCST V2

short gulch
#

ok

#

would i have the same problems if i were to take a module ELRS

#

and a reciever

hexed pagoda
#

well, your problems are sorted for now

#

ELRS also needs firmware flashing, BUT, it can be done over wifi

#

and the guides are EXTENSIVE

#

like, ELRS has the best documentation of anything in the hobby

short gulch
#

ok that's a nice point

#

so ELRS in 2.4 ghz

hexed pagoda
#

ELRS exists in both 2.4GHz and 900MHz variant

#

your R9 (900Mhz) module can be flashed to ELRS

#

and some R9 receivers can too

short gulch
#

so i dont need to buy a new module

#

just a new reciever

hexed pagoda
#

well, as I said, I wouldn't recommend 900Mhz in europe

#

I tried it, it's not ideal

#

however, you can try it on your side

#

it's just that ELRS 900Mhz hardware is hard to find

#

2.4GHz stuff is MUCH more common

short gulch
#

so my actual module (flashed) would be 2.4 or 900?

hexed pagoda
#

R9 will always be 900

#

you can't change the hardware inside of the module to run a different frequency

#

if you want to run 2.4GHz, you need a 2.4GHz module

short gulch
#

how much of a difference would it be in km

#

in europe

hexed pagoda
#

900Mhz has a higher theoretical range limit, as long as you stay away from mobile network towers

short gulch
#

okay i fly in mountains would it be okay?

hexed pagoda
#

on 2.4GHz, people have gone 40km on planes and similar distances on quads (but with higher power levels)

short gulch
hexed pagoda
#

that decides how much flight time you've got 😄

short gulch
#

oh so ?

hexed pagoda
#

if you only have flight time to fly 5km away, then you'll only fly that far

short gulch
#

right

hexed pagoda
#

to fly far you need to fly for a long time

short gulch
#

so what is the power?

hexed pagoda
#

so you need a special long flight time build

hexed pagoda
short gulch
#

ok

hexed pagoda
#

how "loudly" it sends the signals

short gulch
#

i have it on my vtx

hexed pagoda
#

same thing

short gulch
#

but i'm not sure why it w'ont go up

hexed pagoda
#

your VTX is limited to 200mW

short gulch
#

max power?

hexed pagoda
#

yes

short gulch
#

so it sucks a little

hexed pagoda
#

yes

#

long range records for ELRS

short gulch
#

ok

hexed pagoda
#

basically

#

start with what you've got right now

#

just make sure you can see signal strength and stuff

#

and then upgrade whatever is too weak

short gulch
#

but that was my problem

#

i recorded a vido and i lose signal rly fast

hexed pagoda
#

video signal?

short gulch
#

yeah

hexed pagoda
#

did you set your goggles to the same band & channel as the VTX ?

#

MANUALLY?

short gulch
#

yes

hexed pagoda
#

did you use auto-search?

short gulch
#

yes

hexed pagoda
#

then you have yourself to blame for your misery

short gulch
#

o

#

i have the skyzone but i think they only have auto

hexed pagoda
#

they have manual.

#

every goggles have manual setting first, automatic second

#

people are just too lazy to read the manual and think like
"oooh, automatic, I get to be even more lazy" 😛

#

you need to figure out what band & channel your VTX is transmitting on

#

and then send the goggles to the exact same one

short gulch
#

ok that's me PepeKEKcry

hexed pagoda
#

if you wire up DATA to TX3 on the FC

#

then we can make it so that the VTX is controlled by the FC

short gulch
#

ok

hexed pagoda
#

so you don't have to use the stupid button on the VTX

short gulch
#

okkkkk

#

ok i'll try to put the right band

#

so i learned lots of things this morning

#

thanks a lot

hexed pagoda
#

np

#

glad I could help
sorry for the tone with FRSKY sometimes... it's just very frustrating

#

FRSKY did a lot worse things than just the firmware issues xD

short gulch
#

so i'll send you a photo of the drone when finished so you can see the heat-shrinkable sleeves 😀

hexed pagoda
#

😄

#

just... fyi

#

what I say is "do as I say, not as I do"

#

I did my own ugly wiring jobs, worse than yours 😂

short gulch
#

not possible

hexed pagoda
#

I just learned my lesson eventually xD

short gulch
hexed pagoda
#

that's what I'm here for - to prevent people from having to learn them the hard way xD

#

oh no why did my VTX blow up again kekw

short gulch
#

also i'm gonna strap a thumb on the drone soon

short gulch
hexed pagoda
short gulch
#

no wayyyy

hexed pagoda
#

dead serious

unknown.png
short gulch
hexed pagoda
#

yikes

short gulch
hexed pagoda
#

I hope you're balance charging batteries 😂

#

btw, what charger have you got?

#

if it's blue imma flip

short gulch
#

about that

#

...

hexed pagoda
short gulch
#

i kinda broke my balancing port....

#

of my 4s battery...

hexed pagoda
#

ah

#

lol

#

you're only like the 4th person this week

short gulch
#

that'smy charger

hexed pagoda
short gulch
#

yeah

hexed pagoda
#

lipo detonator 2000

short gulch
#

we can say that

hexed pagoda
#

those chargers are very dangerous

#

I know from personal experience.

short gulch
#

oh you had the same?

hexed pagoda
#

it's a B6 knockoff

#

all of them suck

short gulch
#

an advice for one ?

hexed pagoda
#

in regards to the battery connector
buy 4S balance lead extensions

#

and sacrifice them to replace the broken connector

short gulch
#

?

hexed pagoda
short gulch
#

oh it exist?

#

but should i buy a new charger?

#

if it's dangerous

hexed pagoda
#

right now the battery is a more pressing concern

short gulch
#

oh you saw nothing...

hexed pagoda
#

do NOT charge batteries without balancing

#

seriously

#

they will blow up

#

that's why that radio blew up

short gulch
#

oh

#

and i never carged my radio battery

hexed pagoda
#

there is a fixed number of times that you can do unbalanced charging
That number is between 0 and 10 usually

short gulch
#

charged*

#

uh

hexed pagoda
#

with old/hurt/crappy batteries, it's very close to 0

hexed pagoda
short gulch
#

thats my old one

#

il'ts like a balloon

hexed pagoda
#

yikes

#

that's trash

short gulch
#

now i only buy tattu battery

hexed pagoda
#

GNB are great tbh

#

this seems like user error xD

short gulch
#

oh

hexed pagoda
#

tattu are great too

short gulch
hexed pagoda
#

in regards to the charger
these chargers tend to fail progressively, after about 1 year of (Very) heavy use
they take longer and longer to finish charging, right at the end when the battery is almost full
their balancing circuitry slowly fails
when it fails, it's 50/50.
the charger will either kill itself and drain the battery
or, it will overcharge the battery until it explodes

short gulch
#

okayyyyyyy

hexed pagoda
#

your charger will handle it with no issues

short gulch
#

ok

hexed pagoda
#

well, if it has the right connector 😄

#

anyway, just be careful with the charger

#

know the symptoms

short gulch
#

yeah

#

ok

hexed pagoda
#

for a replacement, ask in #🧾shopping-advice

short gulch
#

i was gonna ask

hexed pagoda
#

oh, battery repairs:

short gulch
#

that's nteresting

hexed pagoda
#

make sure that the pins in the balance connector don't touch each other

#

that's the same as shorting out the battery

#

it will light itself on fire (the connector)

short gulch
#

i learned evrything the hard way

#

(about fpv i mean)

hexed pagoda
#

xD

short gulch
#

what you don't know too

#

is that i had 2 tinywhoops before this drone

#

both never worked

hexed pagoda
#

F

short gulch
hexed pagoda
short gulch
#

so true PepeKEKcry

hexed pagoda
#

btw
if you think your charger is bad

short gulch
#

that's yours?

hexed pagoda
#

yes

#

an old photo though
looks worse now

#

and in regards to broken balance plugs

short gulch
#

so you started like me PepeKEKcry

hexed pagoda
#

2018 pics kekw

#

the black charger was powered by my PC psu
my actual working running PC

short gulch
#

at least you have a real imax

hexed pagoda
#

haha no

#

that's a knockoff too

#

and it tried to detonate one of those yellow lipos

#

charged a cell to 4.5V

short gulch
hexed pagoda
#

anyway, gtg back to work

short gulch
#

so thanks for all your advice
