Ed in JXN,



       You failed to mention in your explaination of "p" factor, and 

gyroscoptic moments that the effects of torque on your airplane can be 

GREATLY reduced by thoroughly cleasing your propeller

with "Bubba Jones' PURIFIED PROPWASH".   (available at only the best 

aviation parts suppliers.)

Hi David,



        The culprit is a combination of forces present in all single-engine 

prop-driven aircraft (and most twins), too.  They are:

        Torque:  The twisting force the engine exerts on the prop.

        Spiraling slipstream:  The 'corkscrew' effect of the airflow over 

the aircraft structure, especially the tail group.

        Gyroscopic precession:  Think of the prop as a huge gyroscope, 

which it is.

        'P' factor:  The uneven (asymmetric) loading of the prop, more 

prevalent at slow airspeeds and high angle-of-attack.



        The need for trim tabs isn't the fault of the designer.  Maybe Sir 

Isaac Newton.



        The forces most prevalent in cruise are torque and spiral 

slipstream.  A good explanation for things like this is "The Pilot's 

Handbook of Aeronautical Knowledge", AC 61-23(X?), I don't know what the 

latest version is.  You can order it from the GPO or Sporty's 

(sportys.com).



        For those desiring even more punishment, "Aerodynamics for Naval 

Aviators" should keep you occupied.  Recommended only for those lacking any 

type of social life.

You'll find it just down the aisle opposite the Sea Foam stocks !

Hey Mike,



        Too funny!  Somebody beat me to it with the 'Seafoam' comment, too.



        I would've gone on to explain about the influence of the flux 

capacitor, but didn't want to bore anyone with the obvious.
