I have 3 of these PDB's and I'm quite happy with them. They have most features one would need. Pros: - 5V and 12V BEC built in - Flexibility in BEC behaviour for 12V - Nice and compact. You can sit this straight onto the carbon fibre with a layer of tape below - no problems at all. Cons: - VTX pass-through never worked for me with 2 different VTX/cam setups - Some fibreglass shards sticking out (easily fixed though) One thing worth mentioning. There's a few fools here who don't understand the fact that if you run a 12V BEC on 3S, which has a nominal voltage of LESS than 12V, that you end up with 10V. Well of course you do! You can't increase the voltage via a standard BEC. Idiots. I have enabled the BEC 12V output on my quads even though I run 3S. The reason I have done this is because my VTX can handle down to 7V, so 10V is not a problem for me.
I bought 2 of these , when both are powered from 3S, the 12v bec produce a loud buzz. Even with the bridging pad soldered for VCC. On 4S ,it works fine, no Buzzing. Haven't tried with video equipment yet. Have contacted BG,
