P-Factor

[GeneWeber]

Hi Folks,<br><br>Here are three questions for folks who are flying Gyrobees or Honeybees. <br><br>1) &nbsp; &nbsp; &nbsp;Do you notice any P-factor due to corkscrewing effect of the propeller slipstream?<br>2) &nbsp; &nbsp; &nbsp;What type of tail do you have?<br>3) &nbsp; &nbsp; &nbsp;What size engine &amp; prop do you have?<br><br>Thanks &amp; Best Regards,<br><br>Gene <br>

Gene,<br><br>Do you really mean P-Factor (http://www.av8n.com/how/htm/yaw.html#sec-p-factor)? &nbsp;Or did you mean Helical Propwash (http://www.av8n.com/how/htm/yaw.html#sec-helical-propwash)? &nbsp;Follow the links for the difference.<br><br>Don

Hi Don,<br><br>Thanks, I do mean Helical Propwash, and see that I should NOT have used the term P-factor. The “Pilot’s Handbook of Aeronautical Knowledge” defines P-Factor as asymmetrical propeller loading usually occurring when the airplane is flown at a high angle of attack. <br><br>The handbook refers to Helical Propwash as Spiraling Slipstream. Either way, this is the effect I was interested in.<br><br>Regards,<br><br>Gene
