RE: Balancer, How important??
You can't expect a standard to pop up overnight. In the next couple of years, you'll probably see one balancing tap design win out over all the others to become the standard, but it'll be a matter of the marketing departments from the various companies duking it out to see which one is the most popular with us, the end users. That's how standards are usually developed: Each company comes up with a design that they think is best, they slug away at each other on the open market, and the one that sells the most becomes the standard.
This is a competitive market, and only when there is a clearly dominant force in that market will you see the smaller players fall in line. Until then, to be compatible with another manufacturer's technology is admitting defeat, and might even be patent infringement, punishable by sizable lawsuits. Cooperatin means lost revenue. That's business in a free market enterprise, and why our R/C stuff doesn't cost four times as much as it does.
