You might be interested to see what BVM are suggesting for their Ultra Bandit, 7 JR 8611s plus sundry other servos from ONE battery and ONE JR switch harness. Guess he knows what he is doing BUT no redundancy of any sort and all that power going through the tiny busses in the receiver. Braver man than me, all of my big jets get Powerboxes from now on. Even my little Bobcats get two batteries, switches and regulators.
