I just found this post. Coincidentally I have a separate post on RCU asking if anyone has instructions for this unit. I am trying to set one up for a buddy in a Skymaster F4 and have not had much luck figuring out the jumper and switches for setting up the outputs/inputs. On my post I did get a copy of instructions for an older unit (thank you!) which does seem similar and I will try these out this evening but if anyone has a copy of the instructions for this unit it would be very helpful.
Thanks,
David
