Wow! I didn't realize those were that cheap.
$11 receivers were a major factor in me choosing FlySky gear. Well, I suspect price is *the* major factor in anyone choosing FlySky gear.
I can put whole new plane in the air for less than some people spend on a receiver. If I had $1000+ of fiberglass and balsa (and hundreds of hours of my time) in the air, then I'd make a different choice. I think the cheap receivers are well suited for FT planes, though.
