Gyros work fine on 6 volts normal in a helicopter its the servo that cannot handle 6 volts

hey Tassos I have a 14mz and plan on running dual receivers on a powerbox like this are you running each receiver on battery or does the power box do that for you? Also with all that carbon in there have you ever had any issues with blackout? I fly helis and you have to be careful about receiver ant placement due to the carbon frame blackout. I have been scared to make a carbon plate to mount everything for this very reason.

What are the tree boxes above the power box with airlines coming from them?
