# 3D Printed self stabilizing rocket
This rocket is built to start and land all by itself. The landing manouver is done by tilting the fins on the upper part of the rocket, in order to slowly tilt the rocket till it's horizontal to decrease the fall speed .

# Idea
The goal is to start and land a rocket while not using a parachute ejection system to land the rocket. To acomplish that, the rocket has wings mounted to it s center of gravity. When it launches and reaches its point of max altitude it will eject the nosecone to lower the point of gravity. Then it will fall with the center of the gravity (wings) downwards so the rocket can be brought in the horizontal by tilting the rocket fins.
# Landing
For the landing the nosecone is blown out, in order to change the center of gravity further down.
In the next two seconds the rocket will accelerate to 10 m/s. Then the rocket will start to stabilize its self on the yaw axis and to tilt its self on the roll axis to finally put the rocket in the right position and generate lift to slow down the rocket and land.
