This is a part 2 kind of, of the design of the Rocket S1 it now has wkrking grid fins, landing legs and it dosent have any Jets on the sides (FYI the landing legs on the real thing will be like this, the black base will go up ontop of the Fuel tank and the lefs will fold all the way up so it locks on during takeoff the legs will be out otherwise the airospike will get crushed from the rocket and if it didnt it would just fall over... hence the name Airo SPIKE after it leaves the pad the legs will retract and fold this proces will take arround 10 seconds. After S1 re-enters it will use the rocket ro slow down the re-entry and it will hover while legs deplow and land and same wirh S2 wich hasent yet been created)
