hoonnz -> RE: Adding a bit of realism (12/30/2003 7:49:14 PM)

Yes the top 2 are duplicated on the other side. (Actually after I wrote this I pulled out my photos and reference books to make sure, and I am right, except I had the 3rd lower hatch on the left side, it should have been on the right).
The circular hatches on the horizontal stab are on the top on the port side and the underneath on the starboard, because Vought designed the stab/elevator to work either way - they don't make a left and right, just flip one upside down. Occaisionally a wartime Kiwi Corsair would be repaired with a salvaged tail off a wreck, fitted on the opposite side to what it was painted for, so one side of the horizontal stab or elevator would be white on top and blue underneath.

I also fitted the trim tabs and their linkages on the rudder and the elevators, you can just about make them out in the picture. They are just for show, being far too small to operate, but they look so real that many of my clubmates have flattered me by trying to move the trim tabs, convinced they work.



hoonnz -> RE: Adding a bit of realism (1/1/2004 4:21:58 AM)

On my last Corsair I made the Horizontal stab & elevator with a symmetrical airfoil as per scale by sheeting the stab with 1/4" med-soft balsa and then planing and sanding to shape. It was well worthwhile, and with the new one I am just starting to build I am thinking of doing the same with the fin and rudder as well. A friend of mine built a Harvard a couple of years ago (you call it a Texan) and I remember being startled at how fat the vertical tail surfaces were.
As I measure it, the fin would be 1" thick at the hinge line. Have any of you done this, or considered it? Any comments?

Brian.



voyager_663rd -> RE: Adding a bit of realism (1/1/2004 5:34:49 AM)

It's a Harvard in Canada too hoonnz. I think only the Yanks call it a Texan (AT6).



ganu -> RE: Adding a bit of realism (1/1/2004 3:36:48 PM)

Well, "Southern's" call it a Texan too, and I ain't no yankee!![sm=lol.gif]

p.s. ROLL TIDE!!



hatnikman3 -> RE: Finished Empenage Mods (1/1/2004 10:11:24 PM)

Happy New Year,

Very happy so far w/Top flight gold edition corsair. Approx. 1/2 way complete & was wondering if anyone has jambed the OS 1.20 Surpass under the cowl w/muffler in a reasonably concealed manner. (the picture on the plan appears nothing like my OS muffler!) I can't bear to hear a 2 stroke screamin' away on a Warbird.
Any suggestions are greatly appreciated. By the way, great tip on strengthening the rudder for when she goes ova'!



hoonnz -> RE: Finished Empenage Mods (1/1/2004 10:54:07 PM)

Think about that, do you feel a 4-stroke single gets close to sounding like an 18 cylinder radial?
I've seen and heard a Corsair in the air and it didn't go wheeze-suck-phut-bang, wheeze-suck-phut-bang.

Leave the muffler off the 1.20 and stick it in a Harvard/Texan - that would sound authentic.



RC Flyer 2 -> RE: Finished Empenage Mods (1/3/2004 7:06:33 PM)

nkypockets,

I installed a Supertigre 61 in my Corsair as per the instructions. [link=http://www.rcuniverse.com/forum/m_259482/mpage_3/key_/anchor/tm.htm#1187061] After reading these forums and talking with other folks at the flying field, I decided to mount a OS120 in my corsair. I purchased another cowl and installed it inverted. You will need to open up the cowl to let the top of the cylinder to clear the cowl, this wasn't to bad. As far as the exhaust, if you use the stock muffler you'll need to buy a 90 degree header from OS to locate the muffler under the fuselage. After looking at this, I did not like that big muffler hanging out under the fuselage. I took it off, and bought a Supertigre 90, with a Bisson Custom Muffler (Pitts Style) and a new engine mount. This set-up fits into the cowl very nice and will provide all the power I need.



bkmust -> RE: 1/8 scale TopFlite Corsair Mods (1/7/2004 4:14:46 PM)

CorsairJock,
I have been flying a highly modified TopFlite kit for some time now. Concerning your exhaust, one thing that I did that worked nice was install a block of balsa on the inside, glueing it in place.
This allowed me to cut a deep triangle shaped hole for the 3 exhaust tubes. I then cut aluminum tubes to the correct angle and epoxied in place. I painted rusty brown on outside and flat black on inside. The effect was fantastic. It really give it the depth that you are looking for.



CorsairJock -> RE: 1/8 scale TopFlite Corsair Mods (1/7/2004 5:34:50 PM)

bkmust, Thanks for the tip/ advice. Feel free to post pictures of your exhaust, as well as the entire aircraft in these posts.



voyager_663rd -> RE: 1/8 scale TopFlite <span class= (1/17/2004 1:32:51 AM)

One more mod that I haven't seen (hope I'm the first to mention this [:D] ) is the step in the starboard inboard flap. I didn't see it mentioned in the plans nor in this thread.

I finally found a close up of it and I was surprised to see that this step goes right through the flap. A nice square hole that you can see daylight through (or rather, the ground).

Anyways, another nice little mod for consideration. I hope this is not a repeat.



CorsairJock -> RE: 1/8 scale TopFlite <span class= (1/17/2004 5:19:17 AM)

voyager_663rd, you are correct, and I did neglect to mention the step. This is a simple mod which I have not done yet, it only involves cutting a rectangular hole thru the right, inboard flap. The 'hole' can be seen in the painting I posted in post #43, altho it may appear square in the painting because you can see the belly mounted fuel tank thru the hole. And yes, this hole was used as a step, to help pilots enter the cockpit. There is another step, which is a 'kick-in' type (flush until pushed in) in the right side of the fuelage.

The drawing below is an underside view, showing the step location on the flap (the red area). NOTE, there are steps on the right side only. This drawing is NOT scale (unlike the the others). My trusty D&B drawings did not show the step, so I had to fin another drawing which did, but I don't know the scale of this drawing.

Other 'holes' not mentioned so far are the wingtip hand holds, which are to be used be ground crew (deck handlers) to help manuvers the aircrart around. These go all the way thru the wing tips, and are on each tip.



CorsairJock -> RE: Adding a bit of realism (1/17/2004 2:40:34 PM)

Here is a photo of the Kalamazoo Air Zoo's FG-1D, from the rear, of the inboard right flap with step. Note that to use this step, the flaps must be down. In this picture, the wing is folded up, thus the outboard flap is not visible.

Also note that this photo justifies the angle of the step shown in the preceeding drawing: the step becomes parallel to the ground with the flaps down.



John Rood -> Step cut-out: Check references...not all Corsairs had it! (1/17/2004 3:09:07 PM)

Just in case this will help: Some Corsairs did NOT have the fuselage step...modelers should check their references as to the particular aircraft they are modeling.

Flak -> RE: Finished Empenage Mods (1/17/2004 4:03:39 PM)

One of the most difficult problems with this is the design and construction af the .50 cal guns and ammunition and the rockets for the
later models. Man, some functioning instruments would also be great. Hey, the detail stuff is time consuming!
"Keep 'Em Flying!"
Flak



CorsairJock -> RE: Adding a bit of realism (1/17/2004 7:07:56 PM)

John Rood, thanks for the correction. Preliminary investigation now reveals to me that the step was added into the F4U-1D design, which explains why it was absent from my D&B F4U-1A drawings. Even later variants had a spring loaded door added over the flap step, simular in design to the one on the fuselage side.

Flak, the great thing about many of these details is that can be added AFTER your Corsair is completed, and/ or has flown. The step would be easy to add (subtract balsa, paint to match), or rocket racks (attach and paint to match). Thus, you can build it in somewhat a normal time, have the pleasure of flying it, and gradually add the details as you find time.



hoonnz -> RE: Adding a bit of realism (1/17/2004 11:14:16 PM)

I'm sure the kick-in step over the wing root was on the F4U-1A as well. Certainly the F4U-1 birdcage that I have photo's of has it, and it it shows up in photos in the Signals Squadron booklet I use for reference. It was difficult for the pilot to swing himself into the cockpit with all his gear on, and he certainly couldn't reach without that step.
The pilot could not see the step when getting out of the cockpit because of the curve of the fuselage, so many Corsairs had a vertical line painted up above it as a visual guide.
I simulated the the step with a wee litho plate. The step in the flap I did by eye - I measured it and drew it, but then I did not cut it until I could actually drop the flaps fully on the completed model so I could check it was parallel to the ground. The wing tip grip I showed in the photos in an earlier post.

No one has commented on my post earlier about a symmetrical section Fin/rudder, no takers?

AH. I guess I should explain. I'm only looking for 1D pics so I didn't make the association that the step was FIRST introduced on the 1D. Thanks CJ.



Harpoon -> RE: Adding a bit of realism (1/18/2004 12:02:00 AM)

The wingtip handhold is covered by spring operated plates also (only at the top of the wing). Prove me wrong. Some corsair’s also had steps (with cover plates) in front of the inboard flap on both sides. Like the FG1D on the supplied photos. I have not found out if this applied to all versions. If anyone is looking for holes, don’t forget the shell ejecting holes for the guns. 3 under each wing for 50cal’s and 4 for the 20mm armed corsairs.

Because I’m a serious corsair buff, I have studied the corsair intensively and the best site to date for detailed corsair photos is the restoration page from Vintage Fighters. For those of you that don’t know the page here is the promotion of the site and the link: http://www.bentwings.com/vf/vf.htm



Balsa Master -> RE: 1/8 scale TopFlite Corsair Mods (1/21/2004 1:01:21 AM)

its sad that this post sliped away... lots of good info some of which i already incorperated into my build. what ya think about a 3 blade 14" prop, will it look scale or should i find a bigger 1 (the engine will turn it its a mag 1.08)



kram51 -> RE: 1/8 scale TopFlite Corsair Mods (1/21/2004 2:21:30 AM)

I'm still toying with the idea of a RCV 90. The 2:1 gearing will make a scale 3 blade prop a snap! My only concern is of my own abilities. Do I have the skills to handle scale sized torque? Gotta figure spinning that size prop will require even more than usual attention to the rudder.

Mark



hoonnz -> RE: 1/8 scale TopFlite Corsair Mods (1/21/2004 3:17:57 AM)

I flew my Corsair with a 14x7 Master 3 blade and it flew fine. Take off was a breeze, just open up the throttle and she flew straight with no major work on the rudder. Engine was a Super Tigre 90.
This size prop is too small to be scale, but at least it looks right.

Brian



CorsairJock -> RE: 1/8 scale TopFlite Corsair Mods (1/21/2004 5:38:10 AM)

I use an M.A. 3 blade 12 x 6, which is about as much as my Saito .72 can handle. Altho a long way from scale size, I still think it looks a lot better than any 2 blade prop. If you engine can handle the (3 blade) 14 x 7, I say GO FOR IT!. I'm sure it will look much more scale than the 12" size I am using. And if you go with an RCV .90, I'm sure the ( 3 blade) 16 x 10 would work.

I wish there was a good way to keep this post on the 1st page, many newbies out there who need to know this stuff. Unfortunately, I have about used up all of my ideas on this subject, so it is up to the masses to keep this thread on the front page.

Some one mentioned the spent machine gun casing exit slots ( underside of wing)a few posts back: In suggest you read ALL the posts, as this was covered awhile back, along with the machine gun openings.

Anybody in the Henderson, KY area know when they are having the big Sept. 3 day (or was it 4?) Fly-in this year? I will have a travel trailer/ camper by then, and would like to bring a Corsair (or 2) along. I would also like to know of any other warbird events along the U.S. 41 corridor in Indiana/ central Kentucky area. Have Corsair(s), will travel.



bsherrill -> RE: 1/8 scale TopFlite Corsair Mods (1/21/2004 6:32:38 AM)

I'm a Corsair fan also, and this thread has been great for us scale buffs! Lots of great ideas and pics. Attached is a cutaway drawing of an F4U-1D that I've never seen before that perhaps may help some with scale dimensions. I particularly noticed the slope from the canopy to the cowl, and the not so straight line from the back of the canopy to the vertical stab. [8D] It's 1150x721 size on my computer, but not sure if it will be here after the upload. We'll see.



kram51 -> RE: 1/8 scale TopFlite Corsair Mods (1/21/2004 2:44:15 PM)

I'd be interested in seeing anyone's effort in the cockpit. I'm starting to build the TF cockpit kit for mine. After pouring over Neo's SBD Dauntless I'm tempted to try and add at least some of the techniques that Tom has mastered. Please share!

Mark



hoonnz -> RE: 1/8 scale TopFlite Corsair Mods (1/21/2004 8:10:29 PM)

I detailed my cockpit with bits made up from stuff scrounged from a relative who makes scale plastic models. I put together a few bits to make a gunsight for example - but it was pretty crude because I've not seen a decent picture ( with top and side and front views ) of the Corsairs gunsight. It's very difficult to see down into the cockpit so interior detailing is not too important, but aside from a pilot (you do have a pilot have flying your Corsair don't you?) the gunsight and those selector switches are the most prominent features. Can anyone post some really good gunsight pics?

I've included a pic of my instrument panel, but it's not too clear shooting through the canopy.

Brian
