It is certainly possible to retrofit an existing controller with the new electronics, that is what was done for the first version. To get their support for doing it is rather unlikely in my experience. I have contacted one, btw. Having been around the block quite a few times, established players goals are usually to learn all they can about your designs and stretch out negotiations as long as possible to give them time for their own internal developments to come to market.
There are real design changes possible once you eliminate the need for a very top-heavy long antenna coming out the top of a controller, and the need for such a large battery array. Our controller runs on a single 9v battery for weeks, even months.
I have had a few people use the small unit, they have liked it, although these
are folks open to new things. Others that are top drivers scoff at basically anything different from what they have already..
My opinion has been it is also better to have something that is uniquely different to highlight the difference over existing systems. However, with the Spektrum patch on top of existing systems, you have essentially the same unit when running a non-75Mhz system, so perhaps now the uniqueness factor is not as relevant.
Essentially all the functionality of an M8 is in there. One guy with the new Futaba unit, which has more dials, buttons and knobs than a space station, which does what?? He's not sure.
btw, we could also produce a radio module for an M8 like spektrum. It was my understanding this was not possible with FCC rules without having Sanwa's cooperation, as Novak had.
Apparantly not required, as Sanwa knew nothing of spektrum, and FCC certification is not even specific to r/c,
as I mentioned before, spektrum unit is a
based module. that has a max speed of 62.5K. Our system operates at more than 4 times that speed, and in fact can go even faster with shorter range.
