I used the stock cables that came with Internal Power Connector. I used a 'helping hand' to hold them in place over the V & G contacts while I deposited solder on there.
If you have tried multiple times and it isn't adhering, try using a wick to remove excess solder from there or lightly sand the contact before soldering again.
Jep, tried to sand it down and then the solder is adhering. But I think I but too little solder on the board. When I heat it, it just pops off. I think the cables from the power connector are somewhat thinner. I'll try again later tonight.
Weirdly enough my Phantom assistant isn't working properly with the setup. I'll try rerouting some connections from the Naza and use Phantom2 Assistant to see if that works. FPV system was working great except for the gimbal which tends to look down all the time and not responding to pitch control. So much for 'plug and play' lol!
That's strange. Which gimball are you using?
