Flying to night eh! Aint you been to

--------- Secret Space Program
26 Nov 2019 — He informed his "keepers" that he was from a Planet Called Serpo about 40 light years away in the Zeta Reticuli system. EBE1 worked with the .

Musk can spray a cylindrical epoxy heat shield shell that's rotated on Tesla powered mag lev bearings. The Cyclo rotor shell could fly the rocket both to high altitude at home and low on the Planet Mars. It would help to rotate the heat shield upon re-entry to both Planets. The SN Magnus would re-enter and glide down sideways then land like a feather following a protracted descent trajectory.

Here's a guy flying a rotating paper cylinder: The rocket will fly horizontally like the paper cylinder both on Earth and Mars.

These factors prove how 2 cylinders, in adjacency will impart pitch and yaw in the controls when run at different speeds. Splitting the rotating shield into two indendently powered sections would allow the rocket to do acrobatics.

Flyng a cylinder with a ducted RC fan nested inside covered by a spiraling wing would be very simple. The wind would rotate the spiral wing like a pin Wheel with  gromets  and wire axles on each end of the cardboard cylinder. The rotating wing could benefit  from the 3 spiral Vant force calculus. Naturally, the wing would rotate in the opposite direction from the fan blade for inertial stability. Concentric tubes can house the battery and thrust vectoring servos between the tubes for the aft end steering rudders and fan power. There is a vertical rudder and horizontal elevator that cross in the rear. The 3 wing to bearing struts in the rear can spiral so the exhaust vortex can help spin the wing like a propeller. The front struts spiral the other way. The elevator is notched to give the rudder 90 degrees of movement.

A soda can sized vortexing cycloidal cylinder would be weaponized by Darpa as a guided missile!

This gyroscopic spiral airfoil holds the gliding distance record. A 3D printed cycloidal spiral would rotate perfectly balanced. The fan should be positioned right at the front edge of the cylinder.

A Cyclo rotor rocket could pivot in flight 180 degrees, then fire it's rocket engine and brake to a stop and hover. This aerobatic maneuver involves a gyroscopic characteristic termed "Nutation". This "Spiragyro" rocket can swivel on it's CG to any spherical coordinate: Like a "Nut".

The Vant or Gorlov fins (3 spiral blades at 120 degrees) would be on the inside of the heat shield shell propelled by high pressure gas or compressed air forced through the chamber. Pivot, brake hover and precess. Precession is the opposite of Nutation.
