It's a competitor system.

It's both module based and non-module based (I can't find any information on his website that says what he does, but it SOUNDS like he rebuilds your radio if it's not a module based radio.)

The receivers are smaller, partly because the pins stick out instead of being inside the box (like everyone else.)

He's listened to our feedback quite a bit and has moved to using "our" controllers rather than making his own (which looked quite cartoonish, imho. . . )

I won't spend another several-hundred to get another radio system since my spek is working great.
