I installed my lightbridge on the S900 using a futabe 14sg remote . All the channel are working fine but only up to the 8th channel. Any Chanel after the 8th channel is not working . I conceted the F2-F4 prots of the A2 to the Shut ,Mode , Aux 1 over the zenmuse gcu . When i use the futaba dirctlly bind over the A2 all the rest of channel are working .
