I'm using an MX-20 transmitter with a GR-24 on the CS8 and a GR-16 on the gimbal. I'm trying to map transmit channel 9 to receiver channel 5 on the GR-16 without success. On the MX-20, the "Rcv Ch Map" shows R12 for bind 1 and R08 for bind 2. However, when I press "set" on R08 the output channels start at "Ch 1". According to the manual (pgs 69 & 70) it should start at "Ch 13". Am I doing something wrong or looking at this the wrong way? TIA, Mike
