Status: offline 		Man, bunch of Corsair fanatics or what! I have read all of the posts in this thread and I enjoyed them all, John Rood... Corsairjock you make me laugh too! Sorry to disappoint, but NO the old Royal Corsair has not flown. I'm not afraid or anything, it was built to fly. Over the last year the Indian River flying site has deteriorated massively, the runway now has a sinkhole in the middle of it. With new construction going up on all sides, it won't be long and the 5th largest club in the country won't have a flying site at all. A new site is in the works and has been for years now, but working with the city government as meant cutting through mountains of red tape. A site has been selected but it could be 2 years or more away. For the last year I have been flying hand launch electrics. Every tail dragger that is in the .60 size range quickly noses over and violently flips on it's back when landing at the club field, I won't fly under those conditions. So, my determination to make things ready for flight has diminished considerably if not completely. I will continue to build though, so if you would like to follow me along on another project that would be great.

Anyway here are some pictures of an F2G and my observations: The scoop at the top is flat at the bottom (first picture). On the cowl profile you will see s slight curve down in front of the scoop. Next he shows the cowl as being perfectly round, it looks to me that it has a slight curve on the bottom and is flat at the top. Look at the second picture, the center loop over the engine appears to have a bulge at the bottom, look at my reference lines on the picture. Lastly his wing intakes look wrong, I need better pictures of these but they appear to have no bulge on the bottom, see last picture. I have now redrawn the plans for the F2G three times, but all the formers are done. I would like to get a good drawing showing all the dimensions.
Flow, where are you with your F2G?

Hey Luke, long time since I last visited RCU for a closer look, only short hits to see if it's still there. Sad to see u leaving, good to see you back again.

My F2g is in the finishing stages (well, the plans are :-)). I now know how big I'll build it, because I found the right engine for it.
It's a modellers dream, a Seidel ST770, 7 cylinder radial, 70ccm, thats about 4.2 for you "inchers". I don't know where or how to post it, but I could place some sound recordings on the net if anyone is interested.

About your scale questions:

  • All my pictures show the bottom of the cowl NOT straight
  • Not shure about the scoop curve, looks slightly curved to me, or just flatened out towards the middle (u know what I mean )
  • The wing profile clearly shows a bulge at the bottom, where the oil cooler units are placed inside the wing, but NO bulge at the outer side of the intakes


There are some more pictures of this section on the web, I couldn't find any drawings either

Cheers Flo

PS: FLO is derived from Floh (means flea), I don't usually FLOW anywhere...

Yea, I’m sort of back I guess, It’s probably going to be for a while and then I’ll answer a scale question and I’ll get hit with another, “we love our Corsair’s, all of us that own one and fly it.” You know the answer that has nothing to do with the question!

Do you have a picture of this? I’m going to be shaping mine and I can’t find a bulge on any of my pictures.

Look at these pictures, I can't see any bulge on the bottom of the wing at the intake.

On the next picture you can see the bulge on the bottom of the cowl at the center cowl ring.


Thanks Glory and jmodguy!

Status: offline 		Ok, I'll try to clarifiy...

in the attached pic, you can see that the bottom of the wing is slightly curved towards the fuselage. The "bulge" I mean is visible in the cross-section I drew into the image (sorry, I can't really draw in Paint). It is there to have enough room for the oil-cooler unit (that's the circle in my cross-section).

Maybe we're talking about different things, but anyway...

The second pic attached shows my Seidel radial, complete with glow harness.

Status: offline 		Very good Flo, we are seeing the same thing. The leading edge on all Corsair models at the fuselage is very thick and round. The plastic modeler has his different, see first picture. It’s the type of picture that was confusing me; plastic models and modelers are not always the best source for scale information.

Man that radial is sweet, I’m totally jealous! You buy that new? How big is the cowl going to be to fit that thing? Also what is the wingspan?

Donnie, if I move this summer, especially to an overseas destination then I will probably put the Royal Corsair up for auction, along with some other planes like my F2G. Anyhoot I’ll let everyone know so they can bid if they are interested. Sound fair?

Status: offline 		You're completely right with the "plastic-point", glad to hear we're thinking in the same lines...

The radial is 10years old, it has never run (well, I ran it now). You can't buy them anymore, it was a one man company producing them until the late nineties. However, this guy lives in Germany and is still around from what I've heard and is willing to provide help where he can do. He produced different types of radials, starting with a little 5-cylinder, the 7-cylinder 4.2, a 9-cylinder 5.8, a big 7-cyl 10.8 (if I'm right) and even some examples of a 14-cyl double row radial...
He didn't produce much more than 200 pieces of each type, and they are really worth gold. I got mine second hand from an old man who had to give up this wonderful hobby...
Despite of waiting in a box for 10 years, the radial started immediatly and didn't stop until I told him to, now that's what I call an engine. You should hear the sound, it's amazing.
They provide plenty of torque, at the moment it swings a Menz 24x8 with ease, it picks up RPM like a racing machine with pump.
The outer diameter is some 23cm (approx 9 inches) this leads me to a scale of 1/5.33 => 93" ws. I could go smaller, but there's plenty of urge and I can keep the wing-loading lower that way, use robart#150 gear a.s.o....

I will have to make a custom exhaust system (scale look of course), what material did you use on the royal??

The pic attached shows the backside with the OS-carburettor mounted to it. It doesn't need a bigger one, 'cause there is only one cylinder firing at once. The prop, by the way, does two revolutions until all the cylinders are fired once. No reduction gear though, it's all done by the valve control system. The valve pushrods are not enclosed, so you can really see the rods and valves moving while it runs...beautiful...

See ya
Flo

For the exhaust I would have it custom built, I saw an add here on RCU for a custom exhaust maker. You would need an aluminum ring, and then it would have to be aluminum brazed. Silicone tubing would work off of the stacks to attach it to the ring.

Very lucky find indeed.
Good idea with the silicone tubing for the stacks. But do I really need a collector ring? I thought about running each stack seperatly to the rear end of the cowl and divide each one into two scale stacks. The F2G has seven pairs of stacks, exactly what I need...
I'm not worried about the sound, not too loud and way too cool to "hide away" in a ring muffler.

Now that would be cool! With a tube bender you would be able to make the aluminum stacks as long as you want. Got to see this one. Maybe we can just have an F2G thread with your build and mine, share some ideas?

I prefer the stack arrangement and would use metal flex exhaust tube, easy to work with and lasts too. Keleo do custom work too so that is an option too.
good luck

Hey Luke "Once I thought I was wrong, but I was mistaken!" no Luke you are mistaken, you were wrong.
Just kidding, I wanted to say that ever since I saw your new sig, reminded me of what we used to say in the forces.
I have only ever made one mistake, I thought I was wrong when I was right.

They moved the Carb inlet out of the wing roots on the later airplanes and put them under the cowl. or in the Case of the F2G the Carb inlets are on the top of the cowl. The book by Barrett tillman, Warbird Tech on the Corsair has some good detail shots of it.
Good luck Gents

I'm satisfied we got it right now, most plastic models and conversions are wrong, now why don't you post some pictures US185Damiani? All 3 views that I have looked at are wrong for the F2G, I wish I could measure one of the 3 left in existence! I'm using some measurements, but a lot is best guess. The Royal/Marutaka kit has a very accurate outline so that makes my job much easier.

Thanks for the link Paul, that is what I was talking about. Glad you like my sig, I like your saying too!

Thanks for the link, I already have a ring muffler at home, came supplied with the engine. But I don't really like it alot, as it limits power output, so I'll go for some stack arrangement.

I went to the Tillman book looking for details on the F2G and I found I was wrong! There are no good detail shots at all in it. so I guess That blows that line of thinking.
Sorry!

It's 6.75" wide at the big end and 5" at the little end. The insert divider plates are set at 4" & 8" from the big end. From a top view, this inlet is set back or recessed about 3".

I ordered a bunch of wood for this project and my next one, when it arrives I'll start cutting fuselage formers. Can't wait to start that fuselage!

How about some pics of the same quality of the cooler-OUTLET? They are not covered in any of my documentation...
I think it's the (closed) flap just aft the exhaust-stacks in your first picture

Status: offline 		Yo Flo,

They were taken as ballpark measurements at Champlin's museum of 88854 by another modeler, I just thought they would be a good starting point. Unfortunately the first production aircraft F2G has been traded to the Museum of Flight in Seattle. They won't let you get close to their aircraft at all, so no more measurements of that aircraft. It's the most original one left too, it only has about 250 hours on the airframe.

I believe the exit for the wing intake air comes out of the same bottom flap that is on all Corsairs. This really is the last hard to figure area on the F2G. In the first picture you can see the exit door hanging open slightly, while all 3 views of this aircraft are wrong in several areas, they all show the same door behind the exhausts, as is on all corsairs.

jsut a thought about the measurements: are these measures for the actual inlet area of the oil coolers as viewed from front?

Just another point which I believe is interesting: the bottom cowl flaps are shorter than the ones on the side...
