Porterfield Plans

The original Taylorcraft company produced an Aircraft Service Manual that contains scale fuselage and wing plans and an isometric drawing of the complete steel tube structure.

I am familiar with: http://airfoiltools.com/airfoil/details?airfoil=m6-il

Are scale plans or drawings of the Porterfield Collegiate-- fuselage, wings or wing ribs-- available?

Looking for Tips on Flying the CP65

I’m days away from getting our 1940 Porterfield C65 airworthy after not flying since the 1960’s. I am seeking any advice from those with experience flying the skinny bird.

We do not have anyone in my area familiar with the type for a formal check out so at this point I am planning to just take it out like I stole from Dad’s garage. Insurance is fine with my total tail wheel time( predominately in a Stinson 108-1)but they want 10 hours in type first before coverage… Continue

37-70 , N17027

Hi Porterfield fans,

We own  35-70  N17026, and wondering how many are currently under restoration these days. I'm starting work on 2 LeBlond 5Es and wondering if anyone has had gaskets made for Leblonds, or sources / substitutions for pistons, piston pins, valves, etc. Also if any of you have had cast iron cylinders chromed.  Thanks

AD's on wing struts

The IA I am working with wants to know if there are any AD's on the wing struts of my 1940 Collegiate. He said I should have my wing struts punch tested for thin spots but would like to know if there are any AD's first.

Restoration Continued

A few weeks ago, my dad and I resumed the restoration of his Collegiate.  This time we have help from a friend who's an A&P and another who's an IA.

The wings and engine were rebuilt, and the fuselage was hand sanded and repainted.  We have most of the old parts, but many of them, including the wing struts, windscreen, cowling, and cables, need to be replaced.

We also need a few critical drawings.  At the moment, drawings of the engine compartment for the…

Porterfield Club Newsletters

I have within my fathers paperwork / files a number of Porterfield Club Newsletters. Would current club members be interested in a project to have these inventoried, scanned into searchable PDFs, and either posted to the club site or made available to club members? Any and all thoughts on this would be appreciated.

A Tribute to My Dad

Today is July 10th, 2020. My mother and father would have been married for 80 years today. They have long since passed, but I am still amazed by their lives. Happy anniversary Mom and Dad.

Since my dad was so involved with the Porterfield aircraft, I wanted to re-share a bio that appeared in the Porterfield Club newsletter in April of 1978. It was authored by Chuck LeBrecht with inputs from my dad.

There are some errors, spelling, grammatical, and factual (I…

need fairleads for 1940 Collegiate

I am restoring a 1940 Collegiate and need to find a source for control cable fairleads. The fairleads are .550 in diameter and 1" long. I have checked all the traditional sources and they all have Piper cub fairleads that are .750" in diameter. Does anyone have a source for Porterfield fairleads?

Replacing Bendix SF4-RN8 mags with SLICK 4333

Has anyone preplaced the old Bendix SF4 mags on their CP-65 with SLICK 4333 mags?

It appears that spacers are required between the accessory case and mag to accommodate the required impulse coupler. I welcome any and all information or comments on the conversion process and parts required.

Are there any Collegiates in Michigan?

I have a 1940 Porterfield basket case that I am restoring. I have very little technical information to put this thing back together. I've done OK so far, but could use some pictures of one that is together and flying. I built new wings and am ready to cover them. Progress has been slow as I put the pieces of the puzzle together. 

Please call me if you have one that I could come and take pictures of inside and out. I do not want to disassemble anything or cause any harm in doing so.…

Need fuselage drawing for LP/CP65

Fellow club members: I have engaged a vintage DAR. To assist with the engineering analysis for a C85 conversion for the 65 Porterfield. I need the fuselage drawings to help get the analysis going.  My DAR has contacted the Rankins and they will try to help, but their drawings are still boxed up and things are difficult to find. If anyone has the drawings I would be very interested in getting a copy.  Please help if you can. I am certainly willing to pay for copies.  The analysis will not be…

Need steel channel to repair rudder on 1940 CP50

Does anyone know where I can get tapered steel channel for the rudder of my CP50? The 2 bottom channels are cracked and need to be replaced. If I can't find a source to them, I will attempt to bend some out of .040 4130 steel strips.

Question about Headknockers - aileron balance weights

I have a 1940 CP50 that I am restoring from the ground up.  I  built new ailerons and transferred the lead weight from the old aileron to the leading edge spar of the new aileron.  While in Osh Kosh I saw a LP65 with headknockers for balance weights. My CP50 was not equipped with headknockers. I searched for AD's but could not find any for the CP50. Does anyone know if the headknockers was an STC or some other add-on? My ailerons are quite heavy at the trailing edge. I have always been told…
