I would probably say Charles Parrot's P-47, and that one is classic legal.  My grandfather is finishing a P-47 that he designed back in 1967.  Grandpa's is a razorback and I think Charle's is a bubble canopy.

Hope this helps a little

Edit:  If you are interested in plans for Don Herdman's P-47, send me an email and I'll tell him, and we'll make copies of the plans and send them off to you.

I've built three of the Parrott P-47's, all flew very nicely...with a ST 46. The fuse is fairly massive; my experience with using a .40 engine was not good. With the ST 46(or similar) the Parrott P-47 flies much better than it should...One was later fitted with a RoJett 51, and continues to make great patterns!  Don Herdman's looks pretty good, too, for something bigger than a .40.  Great choices of a warbird legend!

Don is putting an LA 46 in it.  His original drawing, one of the copies you have Bill, show a Fox 40 in it, and I would think it would be a little underpowered.

  if you want the plans for the Parrot P-47 let me know.  alos Pat Johnstons P47 is probably one of the best flying designs - he can scale the plans down AND laser cut you the parts if necessary

Pat's P-47 with a 72 4S has an awesome sound. The wide body makes it look mighty and reverberates a bolder engine sound then a regular model, it adds a lower tone to the engine sound.

I much prefer the Razorback P-47 for looks. Even so, I would contact Pat and get a scaled version of his '47 and modify it. He'll probably suggest 550 sq. inches for a .40/.46LA. Be sure you can adjust your flap/elevator ratio.

T michael jennings,  just read your articale in CLW last night and really enjoyed it.  I suggest going with one of Pat's designs.  Unless you go with Billy Werwages P-47 from Model Aviation.  Then learn how to mold balsa and build a lost foam wing.  Have fun,  DOC Holliday

HI t Michael,

I have a Parrott P-47 and have flown it off and on for 12 years.  Started off with the Fox .35 and after a season went to a retimed FP-40.  Have used a McCoy 40RH in it also.  If I extended the LG a touch, I would definitely use a ST .46 in one.  I will build another, one day, a *little* lighter and with a .40-.46 to start with.  it is a very, very good flying Classic era plane, and suits your criteria.  I am not aware of another P-47 in that size. 

Pat Johnston can scale plans, up or down, and at last word only charged an extra $20 to do it above the cost of the plans (from the Brotherhood of The Ring website).

Mr Hummel,
Mr Little,

Decided to build the Chas Parrott P-47 as the next project.
The above answers lead me to use a OS LA46 power plant.

To guide my building efforts, what are the weights of your P-47's.

Thanks,

The P-47's that I built were 45 to 52 ounces, much depending on the finish. This was with good but not "great" balsa.  Someone laser cut the ribs for me, just can't seem to remember who?...

They are the famed offspring of Butch Cassidy when he and the Sundance Kid went to Brazil....

Well that would be a good story, they are the Brazilian "team" that shows up at the Nats or brodaks.  Bene Rodriguez is a ring leader and Mr Thomas Case is the financial backer.  Either would be great to discuss the merits of the P47 with.  Two very fine gentlemen that may or may not be related to Cassidy or Sundance.  

But does make you wonder....

Don't know if you would be interested but Action Hobbies/Lazar works are advertisers on this forum and offer a partial lazar cut kit of a P-47. It is listed as P-47 from Tom Dixon plans but I'm pretty sure it is the Parrot design. Easy enough to check with them and find out for sure.  8)

Hi Donaldo,

I bought that issue just because that P-47 was in it!  LL~  It took me many years before I finally built one, though.  I really like the way it flies with the proper power.  I am pretty sure that if/when I build another one, I will be using an Aero Tiger 36 in it, or possibly even PA 40UL. ;D

Grandpa's P-47, which is classic legal and will be published sooner or later, has about 575sq inches, and weighs about 52 ounces, along with about a 54 inch wingspan.

Gentlemen,

Setting here studying the plans to the Charlie Parrott's P-47.
Have not started any building.

The Center of Gravity (CG) is located above the wing at the spar location.
Is this the correct vertical CG?

It just does not look correct.  Shouldn't the leadouts should be at the intersection of the vertical and horizontal CG.

If I remember reading about the Brazillion Team,  Pat designed the plane and made short kits for them.  I think he also helped with the trimming of them as well as the building.  Pat is one of the greats and maybe he could repeat his experience on here.   H^^

Mr. Jennings and all.  This is Pat Johnston checking in.  Yes I did design the Brazilian P-47, and yes it can be dropped down to a nice 40/46 sized package.  I would think something in the 560 inch range would be good.  I can do it in both the bubble canopy or razor back version.  I drew plans for both.
Here is the flying impression as I recall from Thomas Case.  He thought that the plane was difficult to fly in the wind and that a thinner wing would be better.  As a result, Bene made up another wing and Thomas was happy with that.  I flew his plane with my original wing and while the turn was very good, it took a lot of muscle to make the corner.  This identical problem was encountered with my big 60 sized Bearcat.  The very easy, simple fix was to slide the elevator connection point up on the horn about 1/8" and then it felt like the plane had power stearing.  For some reason, this trim adjustment suggestion fell on deaf ears and sure enough, in the wind, the plane was tough to fly.  What can I say?
This P-47C/D wing used an airfoil very similar to an Impact airfoil so has a very good performance potential.
Back to the 40 sized version.  I may just go ahead and design one to have in the inventory.  That should be a fun plane and one which would be an interesting subject for many fans of the P-47.  I'll start with the "D" model with the bubble canopy and do the simple mods for the Razor back so all can have what they want.  Give me a couple two or three weeks.

Hi 
What Pat described above as a trim fix for flying in winds is very common for most all planes, Not just a specific one.  The P-47 Pat  designed is an excellent FLYING  plane and great looking !
Another thing that will help turning in winds is to make sure you do not have too much handle overhang. That makes require a lot of pressure on the handle to turn in higher winds

Randy

Thanks for your nice comments on my designs, Randy, and all others.  I just started the new 40/46 sized P-47 design.  I am making the wing area just a little larger since the fuselage will be in the 4.5" wide range through the wing.  This takes a functional bite out of the wing area so it is calculated to be 579 squares which makes it a realtively close equivalent to my prefered size of 560 squares.  So far, so good.  If a comparison to the Werwage P47 is desired, my 60 sized version is relatively close to scale, which gives the fuselage a much rounder look.  This improves the look over practically all other P-47 designs, which to me all look like they were put in a vise and have had an inch or more squished out of them.  My version also has the wing located in the scale location and dihedral installed to raise the wingtips to the vertical CG.  Overall, the appearence is quite scale looking.
BTY, I flew one of the Werwage P-47's in Brazil and it did fly very nicely.  Power on that was a OS70 4-S.
I'll keep you all posted on the design developments as they proceed.

Gentlemen,

Starting to pick up pace.  It is also starting to pick up some weight.

Have the Fuselage Pan, Turtle Deck, and the Top Cowl Deck in place and sanded to shape.
(Beat it to fit, painted it to match in accordance with ASME Pressure Vessel Code.)

The pan and decks are two formed pieces of 1/16 balsa.  Over the engine is a solid block. 

Not sure if the solid block is needed with today's engines.  Seems like it is heavier that needed.

Any suggestions to lighten the solid block over the engine?
Is a solid block needed with today's engines?

Unfortunately, the carved, hollowed block technique is very common with a lot of classic planes which wanted to create the illusion of a round plane.  My method is to get the shape of the fusleage projected and use 3/32" skins over the formers.  Stringers are installed in the top ridge and 45 degree quadrants of the formers which supports the formerd sheeting nicely.  No "strarved horse" look and the weight is amazingly light.
Here's the latest update on the new P-47 design:  The wing is drawn with a wing area of 579 squares.  The flaps are a little smaller than usual which will make the Tail Volume Coefficient (TVC) functionally act a little larger than it is.  The TVC is approximately .450, which is very normal for a modern design.  The turning capacity will be way up there.  The airfloil is a little different than the Brazilian version which is the same as my Bearcat/Mustang wing.  This new airfoil is just a tiny bit thinner and uses an actual elliptical front with the back part of the airfoil transitioning from the tangent point of the ellipse in a stright line to the trailing edge.  We have been using this on the High Performance Ringmaster series and the lifting factor on them is amazing.  The tips will have the arifoil thinner for a more efficient ability to buck the wind and turbulance.
The fuselage side and top views are done.  That will allow me to project the formers.  As described above, this will use 3/32" sheeting for the majority of the fuselage.  An interesting little twist is to use a 1/4" slab for the first 14" of the fuselage sides, which splices into the rear 3/32" sides.  The thicker front side sheeting allows rounding so the nose looks quite scale-like.  In fact, the nose is a little over 4 1/2" wide.  How's that for realistic?  Not a nose in the vice with this one.  I'm excited to see how the whole design comes out.  This P-47 will be a fun plane.  The Razor back version is a simple matter of modifying the rear formers to make up the difference.
More drawing Monday and more to follow...

Pat,
I have your large Bearcat and Hellcat plans; is there or will there be a large P-47?

Thanks,

Hi Jim,

Pat already has the "big" P-47.  That's the one he designed for the Brazilians, AFAIK.  Similar size to the Werwage P-47 in wing area, etc..

Bill,
You're right, of course.  I was wondering about a lage version of this "more scale, smaller P-47".  I haven't seen the Brazilian P-47; does it have the more round fuse?

Thanks,
Jim

Jim,
Generally, the big P-47 has the same overall shapes as the new, smaller version.  The flaps are more of a standard size and the flap hingline is swept forward to get the wing shape right and the flaps to work that way.  With care, this design can be made to come out in the mid 60 ounce range.  The wing area is in the 687 inch area, pretty well in the classic 60 sized class.  Personally, I am enjoying planes in the 560-625 inch range and keeping the weight down in the mid 50's and lower.  This sort of package is so much easier to fly and delivers a lot of fun, because of that.  Bob Hunt writes of this at times.  Smaller planes are less fatiguing and because of that, a person can fly them more and get good practice in.

HI PAt,

I agree 100%!  Although I have no "strength issues" flying a "BIG" plane, it isn't as enjoyable, and the smaller, lighter planes are more enjoying to fly. 

The "Special" F-4-F is going to hit in the range you are talking about, and I really think I will enjoy it......... a LOT! ;D

Latest progress on the 46 sized P-47 for Tuesday morning.  The 1/8" formers are all developed.  Since there are 13 of these bad boys, the laser will be the only reasonable way to cut all of these out accurately.  One new trick I developed, is to install little 1/64" slots in the formers which correspond with the top of the side sheeting.  A little scrap of plywood is slid in and the former is attached to the perfect location.  This allows the formers to be indexed for perfect position in relation to the top of the side sheeting.  The rudder and fin will be very light 3/8" stock.  The tail feathers will be 1/2" stock with ribs.  I need to do all the ribs, yet, but the basic plans are drawn.  Of course callouts will go on.  This sort of thing takes some time.  Drawing is fast and easy.  Detailed callouts take time.  This plane will really look good.

OK, Pat----you got me!  When the plans are ready, I want a set; better yet, a kit.
BTW, the profile P51 I built from your plans really flys well.

Thanks,
Jim

Jim,
Thanks for the report on the P-51 Profile.  I suspected that the Mustang would be a great flyer, as my larger one is amazing.
I E-mailed you a PDF file of the P-47.  Almost done, but a few details to finish.  I'll get back to work on it when I finish woofing my sammich.

Lunch was good as usual.  I have the ribs developed and most of the drawing work is done.  Need to install jig holes and slots in the ribs, but it is coming along well.  Here are the attachments for the fuse and wing sheets as they stand right now.  No call-outs, but you can see what it looks like.  Gittin' there...

The Razorback will follow immediately.  Very easy mod, just alter the rear formers and fin a little.

You know what, Pat?  Maybe someone would want to build a .46LA profile Warbird. This one would be very easy with either a bubble canopy or a Razorback side view! 

Between you and Don Hutchinson, you guys are killing me! LOL!!

Looking real nice!

I just might get mine back out, clean it up and stick a good engine in it, for the "Warbird" meet down in St. Augustine.  Just wish I had used a 4" bellcrank and tall horns back when I built it.  it's kinda "quick" with the "old" control ratios........  but it is one of my all time favorites!

Gentlemen,

Not making much progress.  Too many other jobs with higher priority.

The next step is to Silkspan the fuselage.
Then to install the flaps and elevators.

Larry,
The original P-47 for the Brazilians was almost exactly the size of the Impact and has a very similar airfoil.  Could almost say it is an Impact in drag.  Holler if you want to electrify it.  This little beastie would have a lot of room in the nose for batteries, etc.  Cowl flaps to let out the heat, etc.  Could be a good subject.  Of course, you would need to find help for the electric stuff, above my pay grade.  Get in touch if you want plans, parts.  You know where to find me.
