: 1. How they work, e.g. whether they're inertial or magnetic.
I have heard of two kinds, inertial and piezo-electric.

: 2. Whether they drift.
They do not have corrective circuitry, so they must a little.

: 3. What sort of outputs they produce. I'd guess that they output a
: couple of PWM signals suitable for feeding straight to servos.
You may want to post this question on the rec.models.rc forum, some of the
Heli wizards could give you great info...

: 4. Anything else about them that would be of interest to someone
: building mobile robots on the cheap!
