LYONS, Colorado USA — Nine years ago, Missile Works Corporation set the
hobby rocketry electronics market on its ear when it released the RRC2,
the lowest cost two-stage barometric altimeter available at that time.
Fast forwarding, Missile Works redefines the altimeter market once again.

Jim Amos, owner of Missile Works Corporation, is introducing his lastest
product: the all new RRC2-Mini.  The RRC2-Mini is a small footprint
altimeter based on the company's RRC2 technology and shrunken into an
impressive 1" by 3.15" form factor, small enough to fit within a 29mm
airframe tube.

Using the latest surface-mounted device technology combined with a
silicon resin conformal coating that prevents the sensitive electronics
from being exposed to corrosive residue and gases produced by recovery
ejection charges, the RRC2-Mini is individually calibrated using Missile
Work's new "Heise" absolute pressure standard to operate up to 40,000
feet above mean sea level, attaining pressure resolution to within .001
pounds per square inch.

Another feature is the use of interactive menu programming and operation
by way of push-button pads and LEDs, eliminating the need to use
on-board DIP switches.  Combined with a plethora of "user setpoints,"
the end user can control virtually all aspects of the device's
performance, including: main deployment altitude (from 300' to 3000' AGL
in 100' increments), mach delay inhibit (from 0 to 30 seconds in 1
second increments), drogue Delay (from 0 to 15 seconds in 1 second
increments), main delay (from 0 to 15 seconds in 1 second increments),
deployment mode (for standard dual event deployment, apogee event only
or main event only), and operations mode.  Groupings of setpoints are
able to be stored into two setpoint "profiles" to allow for different
flight regimes.

Just like the original RRC2 astonished the hobby marketplace with its
arrival, the RRC2-Mini is on target to accomplish the same thing,
bringing you all of these features for a retail price of just $79.95!
Missile Works is in the process of totally redesigning their web site to
showcase this new product and should be available soon.

Physical and Operational Features:

 o Small "Mini" footprint (just 1" wide x 3.15" long)... 29mm capable
 o Virtually all SMD construction with silicon resin conformal coating
   to prevent corrosive BP residue damage
 o Sea Level to 40,000 MSL Operational capability
 o Individually chamber caibrated using our new "Heise" absolute
   pressure standard (0.001 PSI resolution)
 o Full HIL (Hardware In the Loop) calibration to null out operational
   tolerances
 o Dedicated "large screw" compression terminals with dedicated power
   switch connections
 o Easy "2 hole" mounting with 4-40 hardware

Functional Features:

 o Interactive menu programming and operation via pushbuttons and
   LED's... NO DIP SWITCHES
 o All User setpoints are stored in non-volatile EEPROM
 o 2 complete setpoint "profiles" are available by the flip of a switch
   for programming or flight ops
 o All flight data is stored in non-volatile EEPROM for post-flight
   recall, even across power cycles
 o Complete on-board diagnostic capability

User Setpoints:

 o Main AGL - adjustable from 300' to 3000' AGL in 100' increments
 o Mach Inhibit - adjustable from 0 to 30 seconds in 1 second increments

   main only
 o Operations Mode - enable/disable low-freq chirping, power-up
   battery/setpoint chirp, and LV lockout
 o 2 complete "profiles" of setpoints are available... setup each
   profile for different flight regime

Post Flight "Log" Data:

 o Peak AGL elevation (feet)
 o Peak Velocity (feet per second)
 o Time to Apogee (in seconds)
 o "Launch" counter (cumulative total flight count)
