Hi you all, just having signed up for flying giants. I have been flying for 8 years now currently 16 and have mostly worked with electrics anywhere from smackdown 3D to scratchbuilt pylon racers, basically slowly building up in complexity and size. Being not a noob to electronics, I still have some issues.

Now I currently own a 89in. 50cc extra 300, it being my first gas airplane won't win any beauty contest but is my first large scale rc over 60 size planes. I've worked out most of the kinks of interference that the CDI puts off and various things, but now have encountered a more interesting problem; Brownouts (I presume). I have 6 HS hites 5645 digital servos in the plane that are obviously pulling quite a bit of power. I have a battery being regulated into a castle creation 10amp BEC that powers the radio setup on the plane. Also a turnigy capacitor set that is supposed to prevent brownouts plugged into the receiver. When I power up the system and I move the surfaces back and forth they randomly stop and resume again after a couple seconds. Having no servo distribution board, would it be worth it to put one in to solve the brownout issue? My dad being a avionics technician and having worked with models for 40+ years suggested taking two of our castle BEC's and running them in parallel to double the amperage for the hungry servo's which would avoid a expensive servo distribution board. What do you think? If I were to get a servo distribution board, where would I even get one that could support a minimum of 20 amps?
