APRA

The APRA is an entry-level altimeter that doesn’t compromise on accuracy and capability despite its low price. It is small, easy to use, and audibly reports your rocket's peak altitude and maximum velocity after flight via a sequence of beeps.  A post-flight warbling siren sound makes finding small rockets in tall grass easier. Features: Works to 100,000 feet MSL, audibly reports peak altitude and maximum velocity after flight. No mach delay necessary for mach+ flights:  Automatic…

Data Transfer Cable

Product Description This data transfer kit incorporates level shifting and USB conversion circuitry to make the logic level signals from the altimeter compatible with standard USB ports. It also includes a USB A to USB mini B cable to connect to the host computer. The included Pnut and StratoLogger software will transfer the data from the altimeter to your computer, save it to a disk file, and plot/print altitude, velocity, voltage, and temperature curves. Comments can be added …

Firefly

Features: •   Works to 100,000 feet MSL, reports peak altitude and maximum speed after flight. •   Unlike many other low cost altimeters, each unit is individually calibrated for superb accuracy, repeatability, and interchangeability. •   Highly resistant to false trigger from exposure to sunlight and wind gusts; tested in 100+ …

FireFly Field Data Display

Plug your Firefly altimeter (not included) into the Firefly Field Data Display and the large built-in LCD will display apogee altitude, maximum speed, descent rate, battery voltage, and more.  Easily change between multiple SI and metric display units (feet, meters, MPH, KPH, etc.).   Note:  Works with PerfectFlite Firefly altimeter only, not intended for other altimeter types.  Firefly altimeter sold separately.

Firewire Electric Match

Discount available for pack of 80 matches(1-box), and is only for groups of 80(ie 80, 160,...)

MiniTimer4

Product Description This timer can be used for ignition of sustainer motors in multistage rockets and ignition of air-started auxiliary motors for added thrust, burn time, or special effects. It can also be used for accurately timed deployment of recovery devices in lieu of the sometimes variable delay times associated with the motor's built-in delay grain.  Delay time can be easily set with 0.1 second resolution via an on-board pushbutton.  If your simulation suggests a 5.4 second …

Pnut

A peanut-sized altimeter with super-sized features!  This tiny, easy to use altimeter audibly reports your rocket's peak altitude and maximum velocity after flight via a sequence of beeps.  A post-flight warbling siren sound makes finding small rockets in tall grass easier. The Pnut collects flight data (altitude, temperature, and battery voltage) at a rate of 20 samples per second throughout the flight and stores them for later download to a computer.  It retains data from the most recent…

Standoffs

Electronic Mounting Hardware package includes (4) each 4- 40 standoffs and screws

Strattologger CF

Smaller “Compact Footprint” version of the popular StratoLogger altimeter is about the size of two postage stamps! This versatile, easy to use altimeter audibly reports your rocket's peak altitude and maximum velocity after flight via a sequence of beeps.  Two outputs are provided for deploying a small chute at apogee to minimize drift and a larger chute closer to the ground to slow your rocket for a gentle touchdown.  Main chute deployment altitude is adjustable from 100 feet to 9,999 …
