Which then leads to.... Why not a giant helicopter? Then you don't need to worry about the symmetry.
- adrianN 1y agoI would love to see the math on how fast you'd need to spin the blades to lift the engine capable of spinning them. In normal operation they spin quite slowly, but due to their lengths the tips reach some ludicrous speeds.

- Gravityloss 1y agoExactly. VTOL is also great as you can deliver the blades really close to construction location. If you installed small props at the tips of the blades, you wouldn't need any torque rotor. I don't know if you still need the variable pitch mechanism or could you lock the blades to one pitch for spin-transport. Helicopter efficiency is quite terrible though so long distance travel would require constant aerial refueling. I guess you could have a probe in the hub. What could go wrong?
