Landing on the Mun with reaction wheels | Stock + DLC KSP

Building upon my success with landing on Pol using only reaction wheels, I thought I'd try my hand with the Mun. This time, the rotor is over a kilometer in diameter and can release the lander with a launch velocity of just under 600 m/s when spun at 10 RPM.

The craft is 648 parts, and over half of those are large SAS modules. Even with that any modules, the rotor still took almost 30 minutes to accelerate up to 10 RPM. Worse yet, I couldn't quicksave just a few moments before releasing the lander because craft rotation isn't saved in the process, so every landing attempt had to start at the beginning of spool up. It took about 10 tries to get the right combination of altitude, orbital speed, rotation speed, and time of release just right, so you do the math on how long this took.

Like my previous design, the four outermost large ore tanks near the axle of rotation are used as "heaviest part" autostrut nodes for the rest of the craft. They are also positioned such that the axis of rotation has the highest moment of inertia, providing additional stability.
