OK, I'm not much of an entrepreneur, and I don't have time for making things, but I had an idea that someone with some ambition and tools might make into a reality. I would really like to be able to use my four or five 2.4 ghz receivers in my 10 airplanes without having to buy 6 more rx's. I think 2.4 lends itself to this because there is no routing of antenna problems. So my idea is a wiring harness that one would plug all of their servos into. The other end of the harness would be the end that you plug into the rx, and it would be set up to exactly plug into whichever brand of rx that you choose (so the design would be for spektrum, futaba, etc). the rx's themselves could be rubber banded or velcroed into each airplane, so when you want to switch airplanes, you take the rx out, unplug that harness, put the rx into the new plane, plug the new harness in, re-bind, and you are flying. So the harness never leaves the airplane. You would have a wiring harness for each airplane. rx manufacturers will never create this because they want us to buy a rx for every airplane.
I would think this is something that would sell very well if anyone out there would prototype it and get it to market. I know I would buy several. Maybe there is a downside to this that I'm not thinking of, but I think 2.4 really lends itself to one using just a handfull of rx's for many many airplanes....
What do you think?
