Hi Guys, just wanted to know if in your 2 axis gimbals you are powering the fpv with a seperate battery
Jean I power with a separate Zippy 3S 2500 battery. Found I had to much noise in the video if I run off of the main battery. Up until yesterday I was powering the 2 axis, Radians and Video from the same battery. Was getting noise from the Radians/Servos so did a quick rewire running the gimbal from the main power bus, through a Castle BEC and leaving the Video only on the 3S. I have the FreeFly HDMI converter power coming off of the tilt Radian and while I get a bit of noise on that signal I use it only for framing when shooting video from the D800. If I am shooting stills I use another small FPV camera that I built a camera mount that attaches to the top of the lens. Again primarily for framing and the lens i have on that camera is pretty close to the 20mm that I fly.
Hey Gary, I was able to figure it out. I just looked at the daisy chain wires and figured which ones to solder to the transmitter. It's working great now. Sorry to bother ya!
Jean because my power to the gimbal goes through the Receiver to the first Radian. And currently for wiring simplicity I am pulling power for the HDMI from the tilt Radian. So end up getting a bit of noise. Will change that in the future if I find it to annoying when switching to the Nikon for the video feed. It's not bad just not as good as it could be.
I"m powering my transmitter off the flight control board. I'm using one of these filters to take the noise out http://www.dpcav.com/xcart/Power-Supply-Filter-L-C-Type.html I"m taking the (+) (-) voltage off thte board and taking it to the filter. The output of the filter is going to the transmitter. I have no noise.
