title_body: Can I power the VTX and FC from the same vbat pad on the ESC?
upvoted_answer: Yes, you can.  Generally, you want to have your VTX and Camera on the same ground (in order to avoid video noise), so this approach will definitely work.  There is continuity on pretty much every VBAT pad, as well as ground, so having a single pad or multiple pads don't really matter much.
  If you're seeing EMI noise effects, I would still highly recommend running a large capacitor directly on the pads of the ESC.
