- Develop new scaled horizon return to centre with initial return from full articulation scaled by the pitch's sine.

Browse source 
* When coming back from a full view pitch using the original algorithm, the initial snap-back from 90 degrees is very aggressive.
* Return to centre speed retuned to be 1:1 to the ms with the tangent at Duke/SW's clamped pitch.
