VTX lead doesn't fit my new vtx
« on: January 10, 2017, 13:44:23 »
Hi,

After a crash resulting in a broken vtx, I decided to buy a new one. After getting help of which one to use I ended up buying one which doesn't fit my lead.

The image below shows the new one on the right and the old on the left. The new one won't fit on my cable, is there any way of making this work without soldering? Do I have to take it back or could I get a connector?

No way to fix without soldering, all the vtx come with their own leads

Did you get the correct connector with the new vtx? (you should have  :smiley:)

Quite sure the only way is to solder the new connector to power supply, and cam.

If you did take it back, you'd have to just get a like for like vtx, to do a straight forward plug in and play!

Don't be afraid of soldering  :laugh:

Looks like a Luminier VTX. It's a good VTX and a good connector, mine is 14 months old and going strong. But you'll have to do a little cable splicing or soldering. Nothing unusual there :smiley:

Technically, if the crimps between the two adaptors are the same you can lift the white tabs on the adaptors and remove the wires then do the same to the other set of wires and switch the adaptor over

I'd be inclined to use the new wiring and it's silicone and your old wiring is plastic coated. Far more durable.

Hi , thanks for all the information.

I was wondering if this method could work. Would i be able to cut the existing wires and attach the new wires to the existing so the connector will fit the vtx.

See below images of existing wires and the new one. Would i only need to keep the red, black and yellow on the new wires as thats the only ones i have on the existing. I have attached the diagrams that show what the cables are.

And how do you attach the two sets of wires? This is tradionally a soldering job

Hi,

My Dad is an electrician and he used these metal clios (think there called crimps) that connect wires together. Would you be able to tell me if i've got the right wires as in do i cut the two red ones completely off (image 3) and leave the yellow black and red and then attach them to the yellow balcjk and red existing ones?

Wire crimps = crap connection  :laugh: and you want a good camera/power wiring connection for FPV !

Crimps are only good for wiring car sound systems and tow bar elecy hookups  :laugh:

Hi,

Ahah I would but I've never tried it and it's extra money as I need to buy a soldering kit! How hard is it, don't want to mess it up!

Soldering isn't that tricky and you can't really get away from it if you're building/modifying quads. Just don't go too cheap, you need a fair bit of power and ideally temperature control. Also solder quality varies quite a bit. I've been using the following..

To add to Revs comments just do not get any lead free solder it will just end in tears unless you have done a lot of soldering you definitely want 60/40 leaded solder for best results also don't forget some heatshrink tubing to cover up those joints

I've just got some 63/37 solder to try, I read it cools more evenly resulting in a better, shinier joint. But I can't confirm that yet. Will report back soon :smiley:

Probably be worth checking the member map to see if there is anyone near you, whilst I agree with the others that soldering isn't hard and is pretty much mandatory, I can understand it being intimidating and the upfront cost is huge just to get two wires tacked together, if you are close to someone they may a) do it for you and b) show you how

That's a fair point, it's a big outlay for one job. TBH a cheap low power soldering iron (<£10) is fine for this kind of work. It's just that it'll struggle like hell to do anything that draws the heat away quickly, like ESC pads and PDB's. Small stuff, flight controllers, etc, no props with the cheap one.

Or as suggested, let us know where you are and someone could help.
