RE: Spin entry? and Snaps...
What "quick reference" are you talking about BigNed?
Here is the rule from the judging guide:
For upright spins entered from upright flight -
When the aircraft stalls, the nose will fall and at the same time the wing tip will drop in the direction of the spin. Failure to achieve this should be considered a "forced entry" and downgraded 1 pt per 10 degree deviation.
No down elevator needed. Give it up elevator, don't climb, then you decide when to add rudder and aileron in the correct direction so that wing drops "at the same time as the nose". It's a timing maneuver that can be influenced by the wind, your plane, and your idle speed.
