KC,
A buddy of mine and myself have this same scenario and I've been monitoring this thread looking for info. Since the new JR receivers, the 921-922-1221-1222, all have a 35 amp bus with the 922 & 1222 receivers having the soft swtch as it is called, will there still be a need for a powerbox type system? Also, considering the batteries are direct connected to the receivers with high amp connectors (I think they are 15 amps) there shouldn't be a need for the power switch. The 921 & 1221 receivers could use the power switch but isn't the available current limited by the 3 amp connector?

Just searching for a lil clarification......

Thanx,
-SK
