On Dec. 22, I asked about Landing and Take Off distance. At this point there has been three answers and then things went silent. It was suggested that cruise and RPM be added OR anything else you might want to add for the good of the information about the PC. Anybody else care to contribute ??BillSee More

Good Idea, these are not information that is easily found. I hope that a number of PC flyers bring this information. For some consistency could we have it put in the following list.

Morgan Walker replied to Bill's discussion Landing and Take Off Distances ?"Bill - I hope a few members respond to this question. If they could add cruise speed/ rpm's/ prop info with landing t/o distances it would sure help someone like me in my performance research. I'm getting very interested in pursuing the…"

Assume Pilot (170 lb.s ??) no passenger, full fuel (13 Am. Gal. ?)hard surface, no wind, 65 hp Lyc.

Bill replied to Bill's discussion Struts---some box some N"Andy,
First thank you for the explaination The term "Flyabout" I went back to several Porterfield articles and found the planes (flyabouts) you were referring to.

"The Flyabout is the Porterfield model 35, usually with a round engine, and the predecesor of the Zephyr and Collegiate.
N struts are rarely used on high wing monoplanes because the wings are adequately braced internally to withstand drag and other…"
Bill replied to Bill's discussion Struts---some box some N"Andy,
I believe the correct term is "Jury" the term "Flyabout" is a new one to me. Basically, I understand the purpose of both the "N" and straight rod, but was wondering if one is better than the other or…"
"Are you referring to the Jury strut, which keeps the struts from bowing to the point of bending on the Collegiate? Or are you referring to Flyabout struts?"
Bill posted a discussionStruts---some box some N
More a question of clarification, I have noted that on some of the Porterfields some have an "N" strut that runs from the top of the rear lift strut to the bottom of the front lift strut while some ones that have been redone have what appears to be astraight metal, (wooden?) rod running from the one lift strut to the other. Advantages, disadvantages, modification ?? BillSee More

Plane for Sale on Main Page
I was looking at the planes for sale on the Main page and noted a blue PC for sale. I can find no date on the ad except an annual of 2009 so I assume it is at least 6 years old. (If this is wrong, let me know.) I can find no N number so my question is what happened to the plane, who bought it or (really a long shot) is it still for sale?
