Hey ciprian,
I have all of mine setup on single channel operation......I have seen guys flick the wrong switch in a panic (which can happen particularly if it is your first jet....the pucker factor is high initially

) and trigger a shut down....not what you need. I think most guys use the single channel operation.
Oh BTW, do you realize now that you are infected and there is no cure for this illness? Congrats on your first jet....enjoy!
My mate has recently bought 3 jets without having flown one and he is seriously addicted like the rest of us....he then bought another the other day but said he would keep it in the box (in denial!!) I suggested that he buy an additional box for his nuts as they were likely to be cut off by his wifey!
Have fun!
Craig.
