Lunar Numbat is an Australian and New Zealand space technology project, which is using commodity open-source hardware and software to build components that can be utilized as part of larger missions, including the White Label Space Google Lunar X-Prize team. Several of the Lunar Numbat build team are members of the Connected Community HackerSpace, based in Melbourne.
Even a small Class C rocket provides some engineering challenges, such as packaging (minimal size and weight) and telemetry (communications).
Jon's minimal Class C payload consists of …

There were issues with the wireless communications, which will be resolved as part of the more sophisticated Class G rocket project.
A future exercise will be to retro-fit, back into the rocket_avionics_class_c rocket, some of the hardware and (more importantly) software components that are being developed for the rocket_avionics_class_g rocket.
