Dave, it's probably a pitot-static tube.. one tube is for the forward-facing opening and the other is for an opening that is flush with the metal casing to measure static pressure which we get by just measuring the air pressure inside the fuselage. Their method is probably more accurate but probably overkill for small UAVs.
The AC-3X integrates accelerometers: AC-3X (593$)
Skookum Robotics is going to release a unit with accelerometers: SK-720 (not released)
HeliCommand from Robbe uses an optical sensor: HeliCommand (starting at 550$)
Those systems can keep a helicopter (or maybe a plane) in place but the purpose of most of the so called flybarless units is to make the mechanical flybar of a helicopter obsolete. There are several products available amongst them is the DIY 3Digi.
There's a reason it's $300, crappy peizo gyros. For $1500 I would assume this one of using MEMS instead.
I've heard lots of bad things about the Gaui, apparently they drift from one flight to the next, which isn't surprising considering they are using pots to trim the gains.

It can't be true that there isn't other gyroproducts build for a rc plane.
I really hope the community would consider making something similar. :-)
