Product Name: Thefpv Chaos Vtx V2 Video Transmitter (25-1200mw, 2-6s, Vtx Telemetry / Control, Mmcx/Sma) × 1
Brand: Unmanned Tech
The Vtx looses/drops output power after a minute or two of flight making the transmission unsuable, tried different channels, power setting, antenna and Vrx/goggles. same results unfortunately
I tried different channels, power setting, antenna and Vrx/goggles. same results unfortunately
The picture suddenly becomes dark/snowy and the signal is lost. after power cycling the video returns.
Is this on the bench that it happens? As the unit will reduce the VTX output power as the unit gets hot to protect itself, and this can happen when testing on the bench without any cooling airflow over your drone.
If its happening in flight, then is the unit again getting any sort of cooling airflow over it?
Could you send over a photo showing how you have installed it and I can get this passed on to investigate further, if the unit itself is faulty we will get it replaced for you.
Thanks Alex,
I realised of the issue when in flight.
The vtx was mounted on the top of the FC with about 8mm of spacing below and 5 mm above under the top deck. I had another VTx mounted on the same place before but did not have an heating issue.
Unfortunately I have desoldered the vtx and repackaged it ( picture in previous message ) . I agree, I guessed too it could have been an overheating issue but it seems to happen also on 25mW output?
Thanks for your prompt help.
Regards
Luca
Can I send it back? I would prefer a store credit as I would purchase a different vtx if possible.
Thanks
