How to Solder an

Transform your #HappyModel #Mobula6 by soldering an #ExpressLRS EP2 Receiver

[@peternguyen3732]

Yes just in time. My FRSKY was starting to annoy me with range !

[@paulm1606]

Great video buddy, i will use this as a base to start replacing my xm+ receiver on my old quads like tinyhawk 2 freestyle, iflight cinebee75 hd etc👍. Thanks again

[@CostaFPV]

Thanks dude 🙂👍

Здравствуйте, а как забиндить с радиомастер поккет с этим приёмником, спасибо

[@oneRella]

Thank you!

[@mariofpvbr2714]

Ótimas instruções...uma pena q não consigo soldar 😬

[@Romanian_Productions]

The switch to ExpressLRS receiver was a success, but now the video range is crappie. Do you have any idea why this can be? Thank you for the video, was helping me a lot!

[@CostaFPV]

Probably because of the way the board manages the power distribution. Over the years that the mobula6 has been around, happymodel has released some crazybee lite updates, mine is version 2.1 and I had no range problems after soldering the receiver. Maybe your case is one of the old versions. Sorry I can't be of more help than that.

[@FPV-Catonsville]

I'm about to attempt this in a few days. What size wire do you use to make these connections?

[@Dimensas]

Successfully?

Hi. I tried installing a happymodel ep2 express lrs external rx in mine and cant get the Serial Rx to save in ports on betaflight. When I set it, it just reverts to disabled every time . I have set the Receiver to Serial and Crossfire in the receiver section. Any ideas? I cant even get the soft serial that I want to use to have VTX smart audio on to save either.

[@rcaddict9558]

Hi mate, thanks for vid, i have inverted 1 IR1 , do i ignore that and just use RX1 im sure my elrs is non inverted, happymodel

[@CostaFPV]

Use rx1 for crossfire and ELRS, left the inverted for frsky receivers and any other sbus protocol

[@rcaddict9558]

@@CostaFPV love to all ,thanks

[@miaowzerz]

What aio is this I’m planning on getting a mobula and aparantly they swapped the aio to a crazybee is it still compatible with this?

[@CostaFPV]

This is the crazybee from the old mobula 6, the first one released. Crazybee f4 frsky

[@miaowzerz]

ouh ok thanks @@CostaFPV

[@Romanian_Productions]

Why you are doing so fast? Thanks for the video!

[@CostaFPV]

Tried timelapse. But you can pause 🙂

[@Dimensas]

How did you bind ? For some reason, I'm unable to do that

[@CostaFPV]

Sorry, I dont use the bind Button. I prefer the passphrase

[@gregdavidd]

ON the FC Manual it says RX1 and IR1. I assume IR1 is the TX1 pad?

[@CostaFPV]

Nope, use tx-rx, rx-tx, and avoid inverted pads

[@gregdavidd]

@@CostaFPV OK but on the diagram you show there is no TX1 on the FC. Which pad is the TX1 pad on the FC?

[@CostaFPV]

@@gregdavidd look again, ir1 e tx1 are very close each other

[@balajiprasad9046]

Hi I have difficulty making the solder stick to the pads on FC...what could be the issue?

[@ryanjones6837]

Make sure your iron is hot enough and try leaded solder as I used to use unleaded and nothing would go to pads or anything. Did you manage to get it working?

[@balajiprasad9046]

@@ryanjones6837 yes.

[@Azgorsky]

rx receiver >tx flight controller tx receiver>rx flight controller?

[@CostaFPV]

Yes 🙂

[@ALWA7SHSEX]

How much does it weigh now?

[@CostaFPV]

1g more then the original mobula 6 weigh

[@Roadking013]

What was the little black piece you set the Rx into?

[@CostaFPV]

Dude, I am no longer using that because is too heavy. Using double sided tape. I dont remember where I found 😕

[@Roadking013]

@@CostaFPV right on. wasn't sure if it was a 3D print part or something. I was gonna use double tape but thought you had something better thanks though!

[@cleitonkp]

641 mAh com o mobula6, que milagre é esse?

[@CostaFPV]

Não posso contar meu segredo 🤫

[@cleitonkp]

Kkkk. Tem q calibrar isso aí. O meu estava marcando mais de 1000 hj. 🤣😬🤣
