Eggtimer Apogee – Kit


5 in stock

SKU: ET-AG-K Category:


Wizard Rockets is proud to stock the Eggtimer Apogee deployment controller. This compact piece of electronics measures your flight altitude and can trigger a single ejection charges at apogee.

This product is ideal for those fliers who are unable to use motor ejection, perhaps due to rocket design, a flight exceeding the motor delay options or on a motor whose ejection charge is too variable to be reliable for the flight.

These kits are sold unbuilt. Reasonable soldering skills are required to complete these kits, though they can be assembled within an hour with a steady hand.

Once complete further integration work will be required. Full documentation for the Eggtimer Apogee is available on the Eggtimer Rocketry website here.

You will need:

  • Reasonable soldering skills. These components are all through-hole components and therefore, by the standards of modern electronics, are relatively large.
  • Some electronics integration (simple soldering) to provide the power switch required by most safety codes (see the UKRA Safety Code here).
  • A suitable power source.
    Wizard Rockets recommends a minimum of a fully charged LiIon battery (3.7-4.2v) if using electronic matches and a minimum of 6v for high current igniters. Maximum recommended voltage is 12v.
  • Electronic matches or igniters.
    Wizard Rockets recommends the orange-wired firework igniters readily available online.
  • A method of integrating the ejection charge(s) into your build.

Wizard Rockets recommends that all ejection charges are ground-tested before flight to ensure that ejection is reliable and consistent.
