Q Tip
G'day!
Noticed on a Twin Commanche the other day that all its props were bent on the tips by about 90 deg. I was told its something called Q Tip. I've never heard of it before. Any of you aviators tell me how it works?

Q-tip propeller blades are formed by bending the tip section of the blade 90° toward the face side.
Aerodynamic improvements include a reduced diameter and decreased tip speeds. This results in quieter operation and reduced tip vortices. The 90° bend reduces the vortices that, on traditional blades, pick up debris that can contact the blades and cause nicks, gouges and scratches.

Not sure if this is apocryphal -
I heard the tale of an FAA inspector walking down the flight line, encountered an aircraft with Q-tips, and wrote up a defect report on the spot grounding the aircraft.
The owner had to pay the local shop to do the paperwork to clear the "defect".

An aircraft with the engine removed?
Well, the cockpit should have a had a prominent placard warning the pilot that the engine had been removed... Part 91 requires that for all unserviceable parts don't you know.
Of course, the aircraft MEL may have permitted flight with the engine removed. In this case, the inspector was definitely wrong to ground it.

Octa,
Reminds me of the story of military pilot training where pilot us'ed aircraft (Vampire) due inability to get the thing to start. No engine. Was a set up but dont recall if it was instructor or a student.
