I wonder how they hold control surfaces in place when the stick centers? I would assume the radio is so fast that it would bring the surfaces back to trim. If I used a switch to lock the attitude I think I could do this today. I already have the code running to maintain Roll and Pitch attitude.

Theres one for 300 bucks. Is also used for flybar less helicopters. But i don't remember the brand.

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.

No is not that one... ANd no is not crappy peizo is normal MEMS gyros i saw it without the case...

$1500 is only 15 Euros but having some guy who looks like Chris with a goattee talk about it is priceless.

Weird world Jordi, good spot, I think we should be told.

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.

Surely this isn't the first, works a dream though!
