Just after some more advice if anyone could be so kind!
The other day I took my drone out for its first few flights and on the last flight I landed, lets say…a little heavy…The UFL on my VTX ripped clean off taking the antenna golden solder pad with it! I was Gutted…
I had then scoured the web to find out if this could be fixed, and with many different types of VTX, yes they could well be repaired or (hard mounted?)
However, with this one I couldent find anything! Especially since the solder pad was torn off anyway.
Its a Holybro Atlatl HV Micro.
I then brought another one, and installed it just fine.
But I cant help feel that its a bit poorly designed?
As you can see by the picture there is very little support even from underneath.
What does anyone reccomend? Add more solder on the sides? Or pins? Or a load underneath (under the board) ? Or can a good glue sort that also? If so what kind is best for a hot UFL?
Im so worried it will simply ping off again…even from a little tumble!
This is just an assumption, but has worked for me in the past.
The active part (centre) should go straight to a component. Maybe a cap or inductor, dunno cos I didn’t listen in electronics school as I thought I knew it all. A wire from the mmcx centre to the below may work, then heavily solder the grounds of the mmcx. Other than than, it does look weak.
Have you got adequate strain relief on the vtx antenna/pigtail? Couple of cable ties should help protect your new one (although there are no guarantees with fpv) lol
Hi thats bad luck. I’d do as others recommend strain relief on the antenna cable plus reinforce the connector. I’d use hot melt as its good filling gaps use it over the pins/pads and then fill the gap between the mmcx and the white connector to give extra strength (careful you don’t get glue in the qhite connector might be best to tape it close first) and then a dab on the opposite side and if you have space underneath.
Also in the assembled picture it lools like the red/blue/yellow/black twisted cable is pushing the antenna cable up from flat. If thats the case then the tension would have caused the disconnect when it had the hard landing shock. Suggest you try to get the antenna cable to run flat and strain relief it and put the twisted cable over the top if possible.
Hi @Yith yup could be a problem if the VTX is over the 80C on a regular basis although you could use the specialist hot melts like polyamide and polypropylene which have higher melting points. An alternative would be a little 2 part epoxy like araldite or plain car epxoy resin. Although tough to remove if to ever need to
ill give these suggestions a shot!
