Flying Models Ivan Munninghoff had good things to say about the X-Plane software as far as setting up and testing new designs. Does anyone on this forum have experience with this sim?

I want to connect my Multiplex MC 4000 transmitter to the PC and utilize the full 12 channel capabilities. I'd prefer to buy a ready made interface but would make one if the information were available.

I sent for the software but am still waiting for it. What is your experience here?
