Thanks guys for answering my earlier post. Shame about the deadzone for such a pricey joystick. I guess I'll also have to make some kind of wooden platform to set it on as the vinyl on the couch doesn't like suction cups.

Another Q on the Ace Edge, it doesn't say anywhere what the two dials (the smaller and larger gray rotatable "buttons") do or what their purpose is. I'll probably end up looking noobish...but I really can't figure it out.
P.S. Stupidity Alert: I've been saying "Aviator" instead of "Ace Edge" for my past 3 or 4 posts because I've seen it so many times in other posts...So If anyone could answer my last question as well as this one (What is the trim button on the ACE EDGE, not the aviator, that would make me feel a lot less dumb. Thanks in advance.
