Voltage drop under load

[Taildraggerrc]

Also to the OP you might look into replacing the switches to the jr e switch. They have a deans connector from the battery end and 2x jr out to your rx. This will give you the current advantage of one more plug in parallel

I am most certain your issue is the bottleneck on each switch going to the rx with one male jr plug. Also the e-switch is fail safe

I am running the xg11 as well. On my 108" extra with 2x 2500mah a123 and power safe 11 channel rx I get a one tenth voltage drop during a crankshaft! I'm so,d on these type of receivers..

Powersafe RX's are awesome. Too bad the others can't come out with something like that.
