Bugman, I have done all the searching and read so much stuff it gave me a headache. What I was after here was how many people, if any - do what I do and fly simply with two switches and two batteries on one receiver without doo-dads. Didn't really want to hear from the multi-do-dad crowd. Maybe should have said that.
But, to contradict myself; lately, I have been having second thoughts.

I would ask a question. Do you have a link, by chance, to a nice article or site that comprehensively deals with a dual receiver setup.
