The Hybrid Bay Kit is a complete set of SMT Designs parts that can be assembled into fully functional electronics bay (customer supplies coupler tube, devices, & batteries).

The electronics bay is a completely self-contained bay with an accessible through-wall arming switch, charge canisters (if needed), shock cord attachments for a recovery system (if needed). The bay is available to support Mach1 thin wall fiberglass, 1/16 inch thick walls such as Always Ready Rocketry Blue Tube 2.0, and thick walled tubing such as Rocketry Warehouse.

The bay includes bay mounting on both ends to allow for a wider variety of construction options (the BT60 Hybrid bay mounts on one end only).

Additional device support and battery carriers are available, as well as, replacement charge canisters.

The bay can be ordered in any configuration from no deployment connections, single, dual and redundant deploy.  A bay with no deployment connections could be used as a tracker or other electronic device for example.  Single deploy can be used for nosecone bays or a bay designed to replace standard motor ejection. Please contact SMT Designs if a nosecone bay with dual deploy is needed for the single ended bay.

For all configurations, the number of deployment channels is selectable (two isolated connections per channel - four maximum channels).

The number of charge canisters for deployent bays can be set to none, one, two, three or four. While the charge canister mounts are proprietary to SMT Designs, we do recognize that there are other options available for deployment such as cable cutters and CO2 ejection systems, so charge canisters may not be useable in all bays.

Important notes:

  • redundant (two altimeters )bays requires two module slots, so the minimum length coupler tube for redundant bay is 7 inches.  If a redundant bay is needed for something shorter, then please get in touch with SMT Designs to discuss solutions.
  • The threaded rods included with be a length required for either the specifc bay length or to support the longest adjustable bay that is ordered. They may need to be shortened if the tube is shorter.  Shortening them can be done very easily with one of the crimp tools that have the feature to cut machine screws. A sander or file can be used to chamfer the rod ends.
  • hard plastic centrifuge tubes should not be used as an insert into a charge canister.  The hard plastic actually becomes shrapnel whne the black powder is ignited which can damage the canisters as well as the rocket.
  • The AltusMetrum Telemetrum platform is available for just the device or with a battery holder for the 1S 850mAh LiPo available from AltusMetrum.
  • LiPo battery use requires a very specific size battery. The manfacturer and model is listed with the various battery carriers that are available.
