My problem with spectrum, its not new technology, its not even really special in anyway. But it is cheap. It feels cheap, its made in the same types of places the $10 receiver is, and I think the $10 might be better. It definately is on price and range. If I had a ubec on the plane or battery pack to blame spectrum completely, I would feel differently about it. I didn't have a servo bind, I didn't have low voltage. I seriously doubt a brown out could have happened. But then again, if that's what spektrum blames it on and everyone else buys it, that's the way it is.
My esc's bec changed from 5.02v's to 4.98v's with full throttle on a low battery and all 4 micro servo's moving for over 30 seconds. Just for fun I tested it with some old full sized futaba servo's, and it droped a bit more, but it was still over 4.90v's. Really not sure how much weight I want to add to a less then 2 pound park flyer to feel like my spectrum gear is safe. If everything else on the plane functions perfectly well and only the radio "browns out", then who's fault is it really? I don't think any of us go out to fly expecting a brown out or not trying to prevent it, if its a 1/4 scale or a parkflyer. Imagine if my plane was wot when I lost my plane or if it was at a feild with others?
Part of the reason I swapped to the $10 receiver, I could hear my motor taking forever to respond to inputs when it was far away. This tipped me off to the fact that my servo's were getting jittery, and I could easily see my plane (6channel spektrum dsm2 full range with satelite) further hen I could fly it. The $10 receiver fixed this, and there is evidence of it happening with my parkflyer spectrum receiver. I would rather fly close then see if I can lose radio signal where I might have a hard time flying the plane. Range test is the same 31-33 paces as the full range. I've gotten over 50 for the $10 one, without jitter or a drop in response, and called that good enough.
My radio is a dx6I, spectrum brand batteries always fully charged when I go out, with a new antenna. Unless there is a problem with the radio, which I doubt.
