Default 13mm motor spinner

Already printed, no supports required. Waiting for a combination of city fire ban ending plus nice (not cold) weather to launch on an away pad. To be powered by two A3-4s which will eject after the 4 second delay.

The 45 degree blade angle was chosen simply because it was a guaranteed minimum angle to not need supports. Relative airflow vector may prevent otherwise certain airfoil stall. The combination of factors affecting that relative airflow - upward velocity, RPM and resulting airfoil lift might make for interesting flight characteristics during ascent. Recovery characteristics will also be interesting to discover.

The very sturdy 155mm (6.1') diameter vehicle weighs 36 grams (1.27 oz).
