The Weatronics website does not mention a 12 channel rx, it only lists 8 and 10 channel rx

Come to think of it though, since the rx will do all the splitting between servos and individual servo reversing and travel, the system doesn't need all the channels, most of my jets would work from 7 or 8 channels with the Weatronic splitting it out to the required number of servos. What a Pity the 8 channel Weatronic doesn't have GPS!
