The G-Wiz LCX, HCX and HCX Hi-g are precision, state of the art flight computers for experimental, amateur, high power and model rocketry.

The Gwiz LCX is a low cost, feature packed computer comprised of an accelerometer, high performance RISC processor, and 2 high current pyro driver channels plus a third pyro driver channel and barometric sensor for 2 stage deployment. 

The Gwiz HCX is the simplest full-on flight computer going today! The Gwiz HCX takes the fully featured G-Wiz LCX to a much higher level of sophistication recording features to allow you to record data during the flight, and download it to your computer afterwards.

Unzip before trying to install, and read the ‘ReadMe’ file first.

The G-Wiz use proprietary firmware algorithms to determine the key events in a rocket's trajectory. The key events monitored are:

  • Launch
  • Booster burn-out
  • Sustainer ignition (when applicable)
  • Sustainer burn-out
  • Coast
  • Apogee
  • Low altitude

All G-Wiz are HyperTEK compatible! While some altimeters and flight computers experience reset problems with larger hybrid motors, the proprietary algorithm used in the G-Wiz properly detects the launch and continues to function reliably throughout the flight. Buy and fly a G-Wiz with confidence.

G-Wiz LCX

LCX_sm (Click to Enlarge Image)

Specifications:  (Red features are new to the LCX)

  • 3 Outputs:
    • Pyro output 1 - Jumper select between Launch detect (for clusters) and Burnout detect (for staging)
    • Pyro output 2 - Fires at Apogee detect.  Inertial Apogee is standard, and used by default. Apogee detection based on Accelerometer data is not subject to problems with Mach transition.  Apogee detection based on Barometric data works better in cases like strap-on boosters, where tumbling may occur.
    • Pyro output 3 - Can be set to fire a number of seconds after inertial apogee (ARLISS mode).
      • On the base LCX, can also be configured for stages.
      • Fires at a configurable low altitude, defaults to 800’. Can be configured in range of 10 to 2550 feet or meters in 10 (foot or meter) increments.
    • All Ouputs have optional timer with 1/8 sec resolution.
    • Can handle up to 4 stages.
    • If a timer is used on a stage output, and Apogee is detected before the timer ends, the output will be inhibited as a safety feature.
  • Status Beeper shows readiness at launch, and maximum altitude upon landing, Battery level and continuity of each output.
  • Altitude is Barometric based.
  • Barometric sensor accurate to over 70,000’
  • Metric or English Altitude readout and specification.
  • Analog to Digital converter reads accelerometer and barometric sensors to 10 bit precision.
  • High performance RISC processor uses proprietary techniques to calculate altitude properly. It does not rely on linear simplifications, but follows atmospheric pressure to altitude models very closely.
  • High current FET driven pyro outputs are capable of delivering up to 4 amps for a full second, on the cluster / stage output, and 5 amps one the other 2 outputs.
  • Available in 50g (Standard), 100g and 200g versions.
  • Uses 2 batteries to ensure that the battery driving the pyro output does not interfere with the computer.
  • Low current jumper provided allowing one-battery use.
  • Positive retention header is standard.
  • Configured by default to work like the LC / LCD. Optional USB or Serial card required to configure options.  Flight View used to configure.
  • Unit dimensions: 3.9” x 0.7”, 23 grams
  • In order to program this unit you need the Optional USB card

G-Wiz HCX

 

HCX Specifications: 

  • Pyro output 1 - Jumper select between Launch detect (for clusters) and Burnout detect (for staging).  When Staging, 1st, 2nd, or 3rd stage selectable.  Optional timer as well.
  • Pyro output 2 - Fires at Apogee detect.  Apogee detection is generally based on Accelerometer data, but Barometric Apogee can be selected, and is not subject to problems with Mach transition.  Also with optional timer.
  • Pyro output 3 - Fires at a programmable low altitude, settable in 100 (foot or meter) increments.  Also, may be configured to fire a given number of seconds after (inertial) Apogee instead.  Also with optional timer.
  • Pyro output 4 - User programmable. May be turned on with one event, and off with a different event. Or with an event plus a time delay in either case.
  • Status LED / Speaker shows and beeps readiness at launch, and maximum altitude plus optional maximum speed upon landing. Readiness consists of self test, Continuity checks, and both CPU and Pyro battery voltage levels.
  • Arming jack provided on board, and via terminal block for external placement.  Not vibration sensitive, and continuity checks work even when disarmed.
  • Analog to Digital converter reads accelerometer and barometric sensors to 12 bit precision.  Equivalent to about 7 ft/count barometric, or .03 G per count acceleration.
  • Acceleration and Barometric data sampled and recorded from 62 to 500 times per second (user selectable) along with all detected events.  Included mini-SD (Secure Digital) memory card will hold many, many flights.
  • Mini-SD card is read directly by FlightView when transferred to PC - no more waiting for long downloads!
  • Optional Break-wire launch detect.
  • Optional 3rd analog channel can be recorded and / or used to trigger an event.
  • Barometric altitude to 70k+ feet
  • Altitude selection, and readout in English (feet) or Metric (meters) units.
  • USB or RS-232 connection.
  • Graphing software provided works on PC/Windows, Mac
  • Software and Firmware updates provided free on web.
  • High performance processor uses proprietary techniques to calculate altitude properly. It does not rely on linear simplifications, but follows atmospheric pressure to altitude models very closely.
  • High current FET driven pyro outputs are capable of delivering up to 8 amps for a full second, each.
  • Can use 2 batteries to ensure that the battery driving the pyro output does not interfere with the computer.
  • Optional low current mode (jumper selected) allows use of one battery by limiting current draw.  Works with DaveyFire 28B and Pratt Hobbies WEC-1A.  May work with other low-current matches as well.
  • Standard model (HCX/50) works from -56g to +56g, but models are available by special order for: +/-112g (HCX/100), and +/-224g (HCX/200)
  • Reverse voltage protection on all connections.
  • Positive retention header is standard.
  • Complete with mounting standoffs, memory card, and battery clips.
  • Unit dimensions: 5.5” x 1.1”, 46 grams
  • In order to program this unit you need the Optional USB card
