My build of the Etoh Satevis which is Blue Dog Bureau’s version of the Redstone/Sparta rocket for the WRESAT, Australia’s first satellite launched in 1967. It is a three-stage rocket which uses the Etoh as its first stage, a Staara III Satevis solid rocket (BDD’s version of Antares-2) for its second, and finally a Staara-10 Aethra (BDD’s version of BE-3) coupled with a 50kg probe.

This is meant to be an early satellite and has limited capabilities and a very limited power supply which is not rechargeable. I recommend shooting for an ascent apogee around 200km and it will be very doubtful you’ll get a good circular orbit due to the nature of the solid engine stages.

I have modified each of the stages in some fashion to keep them more controllable. The Etoh stage will have difficulties with some rolling issues but it shouldn’t have a major effect on the rocket’s stability. The ascent profile should require only about 600 to 800 dv for the circularization if done correctly which will allow you to ditch the remaining Etoh stage when you leave the atmosphere.

The second stage should be enough for circularization although due to its solid fuel nature won’t be a precise circularization but enough to get your perigee to around 100km (or more), simply keep the rocket pointed at prograde and you should be fine.

The final stage is permanently attached to the probe, much like the actual WRESAT, and can be used for a further boost or to deorbit the probe once its nearly depleted its batteries.

The rocket’s probe can be removed and replaced with any payload around 50-60kg and technically the third stage could be removed entirely and its weight loss replaced with an even larger payload of up to 80-90kg.

Built in the VAB in KSP version 1.4.4.
