If you're interested in FPV, this portion of the Hetzer build may be informative. Kinda long, but lots of info. If you want to do this in a 1/16 tank and use battery power you need an additional board to step up the voltage, but it works pretty much the same as the step down I use for the fan in the video. I think I could put FPV in a 1/16 Tiger and mount everything to the underside of the upper hull, with the camera in the driver's viewport. I might have to try that sometime, just for kix.
