UST SBtx-700

Solid rocket booster, semi procedural with Vernier Vector engines.

I know the concept is nothing new but personally it is the most effective way to control the pitch of these solid boosters.

The specific system was modified for fixed or low-grade gimbal engines (5° or less)

small Vernier-type engines have the necessary fuel and thrust to correct the pitch of the entire rocket within the solid booster burn time, the RCS are just to avoid roll efects. fins can be used too but it's efficiency decreases as air stops circulating as it climbs in the atmosphere

It is a moderately reliable system (the ignition timing of the engines can be perfected with the correct automated program) doing it manually is simple but requires a little knowledge and precision.

They can be modified as well as the type of fuel grain to obtain the necessary combustion and the adequate time, this can be achieved segment after segment.

They cannot be mirrored, so I recommend copying the booster and using the alignment and connection tools. it has four attachment points so they require some patience.

It is designed for small to medium rockets
