Thanks to all who responded. I found my questions anwsered, also more info on runryder. I now have both the module for my 9c and a spektrum dx7 system. both have their advantages. also one person even rerouted their antenna wire inside the back of the module into the transmitter case to get rid of the plug sticking out of the backside of the module. I use a tray and that is one thing I dislike about the add on modules. more info can be found on the runryder site about this modification.
