A Challenge for Matt Lowne. The Smallest SSTO (stock).
Can you build an SSTO even smaller and lighter than mine?
This is an open challenge to Matt Lowne, because he is a great content creator and has mastered the art of SSTOs across his career on Youtube.
This is no easy challenge, because a smaller rocket needs to be the lightest and carry just the minimum amount of fuel but nothing in excess.
I had to strip my rocket of the fins, the SAS reaction wheels and the RCS thrusters, leaving only the engine nozzles on gimbals to do the maneuvering.
