Walmart Brand Lunar Lander

This Walmart Brand Lunar Lander is my attempt at making a cost-effective rocket for the Weekly Challenge III by Bmcclory. there isn't much else to say about it, so I will just provide a flight tip.
When launching this rocket, disable the RCS until first stage shutoff when you should activate the RCS. given the nature of how this rocket is built, if no rcs is activated immediately after first stage separation, this rocket will start to flip uncontrollably. There is a very small amount of rcs, so only use it when landing, or until you exit the atmosphere of Droo and are able to time accelerate, or else you will run out. I built the Walmart Brand Lunar Lander with cheapness in mind, not practicality.
