About Me:
Enough about me, let's talk about you...
Do you own a Porterfield Airplane?
NC41VT, 1941 FP-65, S/N 875 Has a Franklin 90 installed by Angelo Forte, under a one-time STC, in the mid-50's, and has had the seaplane conversion done to it (would that make it a FS-90?). I just need a cheap set of Edo 1320's now!
Are You a Pilot?
Why yes, I fly...

NC41VT and I are now back home in Vermont! How we got here...

I'm sitting in KMHT, writing this while waiting for my flight which should be wheels up in about 10 hours.  I fly to Newark, then to Seattle, then to Great Falls, and should be wheels down at KHLN about midnight (about 31 hours from now).  Hey, I live in New England!  We can't get anywhere from here!  41VT is at Boulder (K3U9) Airport, about 25 miles south of Helena, MT.  I'll buy a used bike  Wednesday morning (I hope), and pedal on down to Boulder to start prepping myself and 41VT for our…

Update on my '41 FP-65 project

After tinkering for over three years on my Collegiate, the novelty finally wore off for Pokey Gordon and he asked me to remove the old girl from his shop in Helena, MT.  Club member Tim Talen, who has a hangar in Boulder, MT, about 30 miles south of Helena, came to the rescue and arranged for a Boulder friend of his to rent a truck and haul the project to his hangar. 

Tim's is a master restorer who specializes in Interstate Aircraft.  I restored an Interstate Cadet back in the 80's…

Hey Andy! Say, is there any place I can get a complete plan or drawing set, while I keep an eye out for the right project and save $?? Thanks!

Thanks Andy!  I'm still snooping through the site art this point.  Where are folks finding drawings, etc?  And are most parts needing to be fabricated more so that finding spares?

Hi Andy - a pleasure to meet you!  That local Porterfield sold a week after it was posted.  That's OK - I'm in no hurry at all, with other projects to finish first, but I'll save my pennies and keep an eye out.  As far as being a tight fit, I'm a short guy at 5' 4ish but pushing 200.  Does that make me too heavy?  Also I was wondering about the scope of a Porterfield restoration, as opposed to other planes:  comparable in time and skill and $ as, say Piper's? Much harder, and really for seasoned restorers and not beginning ones? etc.  Sorry - lots and lots of questions!

LeRoy was more than generous with his time. I hope I remember a good portion of the information he's shared. I spent two days up there and almost countless phone calls. I have a hanger and feel a privilege and responsibility more than ownership. I have a daughter in Brooklyn so there's a good chance we could meet in the next year.

Im interested in the historic role of the Porterfeld as chase plane and filming platform for the 1st manned rocket flight (Ercoupe) at March Air Field in September 1941.

The pilot who made the flight was a good friend, Captain Homer Boushey who at the time worked at Wright Field. Would value any information from anyone as to exact model of Porterfield, engine type, manuals for the type, prop, markings et al. 

I would like to find a Porterfield with the exact specs. as the one used (there is footage showing it) to purchase and re-enact this historic event.  If your club owner/operators could educate me on that exact model that would be fantastic.

Thank you all for keeping aviation history alive.

All the best-

Bradley

Andy

The encoder is actually remote from the radio panel, I made a "trap door" in the right side cabin wall just below the upper longeron and just behind the instrument panel. The encoder is mounted on the back side of the trapdoor. The altimeter, airspeed and encoder static ports a r connected together and vented behind the instrument panel through a .032 dia. orifice to reduce "gauge flutter" The wiring connections between the encoder and TXPDR are routed up the right side rear edge of the windshield just ahead of the door frame.

FYI, I recall recently seeing an ad by Microair for a low power consumption TXPDR, that would be worth investigating if you a re planning to use total loss battery power system.
Let me know if there's anything more I can help out with

Andy, Yes the wheel pants on my CP-65 are original. I'm extremely fortunate to have picked-up a Porterfield that has been restored to, what I believe, is as close to original as you can get. Fred Hollaway is the gentleman that did the restoration in the late 70's. To give you an idea of the detail Fred went to, he braided all of the control cables in the original fashion with a waxed cotton twine wrap. Just one example of many that make NC37895 very special. She fly's like a dream as well.

Well, it's got a big tail but a C90-12F so it's got a starter and a generator. Yeah, no more propping for me!
