Hello friends! New poster looking for help. I am also relatively new to FPV so forgive my assumptions and anything obvious I am forgetting. I have a Tinyhawk S that I lost video signal on. Assumed it was VTX since I have no signal at all. Figured if only camera was bad I would still get OSD in goggles. I decided to upgrade camera and vtx anyway cause I really like my tinyhawk. Now have the Runcam nano 3 and Rush Tiny Tank installed. Everything was going well for the first few batteries...then nothing! Upon doing some test I found that if I held the vtx antenna within an inch or less of the video antenna I could get a picture ( although bad). Also if I pinch the antenna connection to the vtx I can get a picture but only out to about foot from video receiver. Also sometimes when I boot up for testing the vtx will be scorching, unplug, replug normal. So assumption number two...I have another fried vtx. Now the question, could the flight controller be frying the VTXs? I have check the voltage going to the vtx and it is 4.8 volts. Any thoughts or ideas would be greatly appreciated!
