I am slowly upgrading my fc40 to where I want it. ATM I have a fc40 with walkera h2d gimbal and go pro 3, using the multistar 4k mah with 9" props. I plan on getting the boscam 500mw tx/Rx combo. I am running power to the gimbal using the aux power cables supplied on the phantom. Question is if I run power to the vtx using the same aux power will I place too much of a current draw through the board. I am trying to make replacing batteries as quick and neat as possible which is why I'm only going to use the jst on the battery as a last resort. Next I plan on installing a canbus and dji mini iosd. Which wil draw for regulated power so I'm pretty sure I shouldn't have a current concern with it. Any help or suggestions are greatly appreciated.
