Need a little help with this. My scratch built cessna bobcat twin will have EMAX 2215/9 motors with 2 hobbyking 30 amp blue series esc's and I thought I would add a 10 amp castle BEC . I will be powering 8 - 9gram servos . My question is how to correctly wire this . With the castle bec drawing power from one of the esc's, do I disconnect the red wire from both esc's or just the one that has the bec connected? Hope this makes sense. This build has taken me forever, but I'm getting close to the finish. It will be the classic Songbird from the Sky King TV series.
