I have been playing with an APM1 on an old quad and needed to reference some connection settings but it looks like all the setup pictures are gone from the legacy apm 1.4 pages... If you dig you can find the verbage but no pics... http://code.google.com/p/arducopter/wiki/AC2_Radio - where did all the pics go?
Just a Google glitch. We've sent a trouble ticket and they should be back shortly.
Thanks Chris... had to blow the dust off the old APM to install on a "beater" quad and just wanted to refresh my recall on the hookups... pictures are worth a thousand words.
