I wonder what he is using for a gyro?

The "GyroChip". The specs are on the above web page. 60 degrees/sec
maximum and +- .5 degrees drift/8hours (I don't believe that).

See the following (from April this year).

Dear Mr. Lassen:

The term "GyroChip" refers to a family of quartz rate sensors
manufactured
by Systron Donner Inertial Division - SDID (all of SDID sensors share the

same technology; i.e., quartz not silicone).  Single axis sensors range
from
the QRS11 (highest performance and most expensive) to the AQRS rate
sensor.
Multi-axis sensors include the MotionPak and DQI packages.  SDID does not

sell the sensing element only.  All SDID rate sensors are complete; i.e.,

electronics are integral to the sensor.  The customer is only required to

provide a DC Input Voltage and the rate sensor output will be a DC analog

signal that is proportional to angular rate (angular velocity).
Integrating
the rate output will provide the customer with angle or angular
displacement.

To meet your unit price goals (<$100), may I suggest our AQRS rate
sensor.
SDID provides this rate sensor to the automotive industry for an
anti-skid
control system.  We currently manufacture 5,000 to 8,000 per day of the
AQRS
rate sensor.  In small quantities of the AQRS-00075-109 rate sensor (1 to
3
units) the unit price is $300; when purchased in quantities of greater
than
1,501 sensors, the AQRS-00075-109 unit price is slightly below $100.

If I can be of further assistance, please contact me directly.

Best regards,
