An engineering teacher taught us to always have a notebook next to the bed to jot down any ideas we may get overnight. In this age, that notebook is this computer and this forum the paper...

The Saturn V is notorious for being underpowered on a D12. And marginally stable. So using an E12 or any 24mm central within a cluster of four smaller motors or moving the motor further back from the stock location to facilitate flying with the engine bells are all asking for pain.

The idea is to add four clear tubes as tube fins for added stability, with the added benefit of landing protection.

I did ponder on some ways to make them removable before I dozed off.
