Power boxes
 

My seaplane is going to have some long runs for servo and I also wish to use a seperate battery pack for them. I am told I need a power box? It was explained to me that they couple the seperate battery to the servo leads, which would normally be done by the reciever. I have a Airtronics SD-10G and sense most of my teads are over 24" I figure I might as well have the capablity of seperating all 10 mchannels. Can someone steer me to the correct box? Thanks
