Q tips and CSU's (reference site for)

[Keygrip]

Looking for a good explanation of CSU's and "Q tip props" - anybody know of a particularly good reference site?

Thinks:
Q tips are bent forwards; P tips are bent back (or is it the other way?) Remember the good old FAA ramp checks ("You're grounded: Prop strike!")

Both have aerodynamic principles similar to winglets, i.e. increase effective span.

Trythis (http://www.mccauley.textron.com/prop/govern/systgov.html) site for info on CSU's. HTH

Edit: Just had a quick look around the McCauley site and they have some good tech facts about constant speed props and units, check out higher up the registry and search the site:
