Daryl, the POLKS radio is always on if you don't select a switch. If it doesn't work with the S mix, then do it with the P mix. And all you have to do is slave one to the other. Then reverse the one thats turning the wrong way. Also, if you want to run both elevator servos off the same channel, use a y lead and just turn the horn on one the other way. I have a giant aeromaster and the instructions said the get a "reversed" servo. I scratched my head and just turned the servo horn 180 degrees and presto! No problem.
