Hello,

I tried connecting my drone with my Radiomaster Pocket but it didnt work. I also tried connecting the drone to my goggles unfortunately that didnt work either. Please Help Me!

What I have done so far:
-Changed the PH2.0 to BT2.0
-Cam desoldered itself while changing to BT2.0 and I soldered it back up
-Set up binding Phrase on my Radiomaster Pocket and on the drone aswell

“Cam desoldered itself”
???

"it didn't work"

#

what didn't

tepid knoll
#

Telemetry

#

No Telemetry

finite bobcat
#

Sorry i think not the right chnnel here for that right

ionic nest
tepid knoll
#

💀

#

@ionic nest you did me dirty

ionic nest
#

What ?

tepid knoll
#

You told me to buy the Mob 7 1s that I cant do anything wrong with the FC of Mob 7

#

Now same sht happens

ionic nest
#

What

tepid knoll
#

I shouldve listened to @umbral furnace and buy Meteor 75

umbral furnace
#

i mean probably but we can get this to work

#

show your ports tab

#

and your receiver tab

ionic nest
tepid knoll
tepid knoll
umbral furnace
#

yeah

#

that is very wrong

#

so this is the x12?

tepid knoll
#

yes

umbral furnace
#

ew

#

it's SPI

tepid knoll
#

hahahaha

#

what now?

umbral furnace
#

your Zorro is on the latest version>

#

?

#

Pocket*

#

of ELRS?

tepid knoll
#

3.3.0

umbral furnace
#

can you open the lua on your pocket

#

what hz is it set to

tepid knoll
#

you mean the Packet Rate?

umbral furnace
#

yeah

tepid knoll
umbral furnace
#

uhhh

#

SPI doesn't work with that I think

#

SPI receivers DO NOT support D(D250, D500), F(F500, F1000) and Full Res(100Hz Full Res, 333Hz Full Res) Modes (Packet Rates) and thus will not bind or sync with a TX module in any of these modes.

These are the packet rates that will work: 50Hz, 150Hz, 250Hz, 500Hz.

#

set it to 250Hz

tepid knoll
#

no way

#

you are the best

#

it works

#

now the hard part

#

VTX

umbral furnace
#

right

#

you fixed the camera wire right?

tepid knoll
#

yes it should work

umbral furnace
#

manually set both the vtx and goggles to raceband 8

tepid knoll
#

tried that

#

Like this:

umbral furnace
#

it says it's set to 6 in the top right

tepid knoll
#

yes because 8 didnt worked so I tried 6 didnt work neither

#

I changed it back to 8 now

umbral furnace
#

you have put the antenna on it right?

tepid knoll
#

what?

#

there is already an antenna

#

you mean goggles?

umbral furnace
#

the antenna

#

on the vtx

tepid knoll
#

Do you mean this?

umbral furnace
#

yes

tepid knoll
#

it is connected

umbral furnace
#

yikes

#

uh

#

we can try 1 thing that has worked before I guess

ionic nest
#

Cause if it was disconnected for just a couple of seconds it can hurt the vtx enough to basically kill it

umbral furnace
#

and the vtx set correctly

#

and the antennas are okay

#

plug in battery and plug in the quad

#

and flash it

#

at least

tepid knoll
umbral furnace
#

I assume you can

tepid knoll
#

before I do anything

#

wait

#

This is where it desoldered itselft

#

I tried my best soldering it

tepid knoll
umbral furnace
tepid knoll
#

not my fault it just desoldered itself

#

anyways what do I do here?

#

Or maybe the Problem is that I couldnt solder it well

hollow onyx
#

that’s an issue between the chair and the keyboard

hollow onyx
tepid knoll
ionic nest
#

If you used 450c for 2min maybe it could desolder itself but the board won't be happy

ionic nest
# tepid knoll

Could you send a more detailed photo of this part ? (Take off the canopy and take a closer picture cause here it's hard to tell what's going on)

tepid knoll
#

I can

#

But I will probably return it

#

And get the meteor 75

ionic nest
# tepid knoll But I will probably return it

I doubt they will accept it since you re-soldered on the camera plug but sure, also if we could have a closer look at the whole board it would be nice, just to take a look if any component slided or something

tepid knoll
#

Alright

ionic nest
# tepid knoll And get the meteor 75

Tho the thing you are ommiting is that the f4 5a 1s is far less reliable, I'm going to let you count the number of x12 on this picture and compare it to the number of f4 5a 1s (they are the cross ones, and I'm not saying that they are bad, they are really good, while they work)
What I'm saying is that if you go with the meteor only cause you think it will be more durable, well that's a bad move

tepid knoll
#

I just want a drone to fly with

ionic nest
#

And since this isn't my own picture, I'm going to add my own experience, I have 5 dead f4 5a 1s, and only 1 x12 that died, (and another one that has gyro issues but that was user error since I forgot to plug in an antenna which for some reason messed both the vtx and gyro pretty badly)

tepid knoll
#

I opened the drone now

ionic nest
tepid knoll
#

yes but its just frustration

ionic nest
#

Yeah, but unfortunately user error and bad luck are part of the hobby

#

I can tell that from experience...

#

Happens way more often that you would like

tepid knoll

That's not looking too good, in orange there the capacitor looks like it might have bursted, and in blue there should be a resistor there, check it it is shorted with the pin in red

#

Also the blue resistor looks like it got broken in half

tepid knoll
#

this means "no way to save it" ?

ionic nest
#

This means go check if what I said is right or not cause it will tell us how badly you screwed up

tepid knoll
#

I dont have a proper multimeter at home

ionic nest
#

Just a visual inspection will do

tepid knoll
#

there is no connection between red and blue

ionic nest
#

And is the resistor broken ?

tepid knoll
#

there is no resistor

#

I thought you meant this

ionic nest
tepid knoll
#

but there is no resistor

ionic nest
tepid knoll
#

yea I messed up

ionic nest
# tepid knoll but there is no resistor

Well, since the ufl is right on top, I'm assuming this is part of the vtx section and a vtx needs some really clean and smooth power, so that probably fucked it up

#

Plus there is that capacitor next to it that blew up

tepid knoll
#

this means the fc is dead

ionic nest
#

Most likely

#

Well, the vtx part at least

tepid knoll
#

Well then

#

This is where my journey ends

#

I couldnt even fly once

#

FPV hobby really is time and money consuming

tepid knoll
ionic nest
tepid knoll
#

like which soldering iron

#

etc..

ionic nest
# tepid knoll Which tools do you use?

Ts101
A 70yo 2kg caliper that is actually way more accurate than most digital calipers
Ifixit it tweezers and manta kit
The "sexy screwdriver set" from tbs
An omnifixo
A bunch of other stuff I just have laying around on my desk that just come in handy from time to time

tepid knoll
#

Desk?

#

working desk?

#

or is the desk only for your quads

ionic nest
# tepid knoll working desk?

Yup, just my normal desk,
I do have a workbench with all the tools my grandpa accumulated over the decades, but it's in my basement and I'm too lazy to go in my basement when I want to work on my quads so I just do it on my desk

tepid knoll
#

I see btw if you dont mind! Where are you from?

ionic nest
#

The french alps

#

Best region in the world in my objective opinion

tepid knoll
#

Nice nice

#

You have your peace

#

@ionic nest I will buy the Meteor 75 Pro as my last hope

ionic nest
#

Cause that thing is a chonker

tepid knoll
#

I will fly only outdoors

#

and indoors if there is enough space

#

like in a big room

ionic nest
#

It's an 82mm

#

It's much bigger in the air than a 75mm

#

Go with a meteor75 instead

tepid knoll
#

whats the difference?

ionic nest
#

The pro uses 45mm props

#

The standard uses 40mm props

#

It's actually a big difference

tepid knoll
ionic nest
tepid knoll
#

yes but what makes the difference

ionic nest
#

Uses bigger props

#

More thrust

tepid knoll
#

is it bad when I have 45mm props and its 82mm

ionic nest
#

More weight

ionic nest
tepid knoll
ionic nest
tepid knoll
#

I want a whoop

ionic nest
#

An 85mm is a whoop

#

And 85mm uses some 2" propa

tepid knoll
#

I have setup only for 1s

#

1s batteries

#

charger for 1s

#

what do you think about meteor65 pro

#

is that also like 72mm?

ionic nest
#

It's great

#

Just throw the gemfan props in the garbage and get some 35mmx3

#

The 35mmx3 are way better

tepid knoll
#

There is really no quad which I can fly when I get it

tepid knoll
ionic nest
#

Well, a meteor65pro will fly on some 300mah 1s which is what I assume you have

ionic nest
tepid knoll
#

its 31MMX3

ionic nest
#

Gemfan 1208

#

If you want the full performance of the meteor65pro you need the 35mm props

ionic nest
tepid knoll
#

I have it next to me

ionic nest
#

Well then you swapped the props

tepid knoll
#

No these are the ones that came extra

ionic nest
#

GF1208

tepid knoll
#

Just tell me a drone with prop guard to fly lightly indoors and mostly outdoors and I dont have to change a thing

ionic nest
#

It will take you like 10 seconds

tepid knoll
#

ok got it

#

then I will buy that

ionic nest
#

Tho make sure it's the pro version

#

The regular version is very underpowered

tepid knoll
#

How much difference is there between Meteor65Pro and Meteor75Pro? (Power)

ionic nest
#

Well, there will be quite a bit of difference, but the meteor65pro will be infinitely better at indoors
