I'm about to order the RDS-control system (Rotary Drive System) for the ailerons, but need to know how much the ailerons on the Corsair deflected in degrees if possible.
Anyone have any pictures from a flyable Corsair with ailerons deflected max?

Cheers,

The TF corsair calls out for 15 degrees of travel. I know thats not a 1/6 scale, but its all I know The 15 degrees works out to be about 1/2" of travel

Thanks Chilie,
Thats why I asked for a deflection angle in degrees, as it's independent of scale

The reason I want to know the aileron-deflection (in fact I want to know the deflection of all movable surfaces) is to have one more scale-item to reproduce for the scale-judges.
The deflection I need for flying can be programmed easily.

Cheers,

I make no promises that the information I just provided was "scale". That was just the information that is in my manual. I have no real idea how many degrees each of the control surfaces move on the full scale.

A Paul Matt drawing shows "50 degrees max flap deflection". Another Vought factory drawing shows the same thing.

[img][/img]Don't know if this is full aileron deflection, but it looks more than 15 degrees.

Here ya go , this is right out of the maintenance manual ..

AILERONS
19 deg up
14deg down

TRIM TABS
15 deg. up & down

Range of Movement of Control Surfaces
(shown in degrees)

Ailerons (from neutral): 19 up, 14 down
Flaps: 50 max, in 10 degree increments
Elevators (from streamline with stabilizer): 20 up, 16 down
Rudder (from streamline with fin): 25 port and starboard

Trim Tabs
- Elevator (from elevator trailing edge): 10 up, 20 down
- Rudder (from rudder trailing edge): 18 port and starboard
- Ailerons (from aileron trailing edge): 15 up and down

Balance Tabs
- Aileron (referred to median line of aileron): 26 up, 38 down
- Elevator (referred to median Line of elevator): 16 up, 20 down

NOTE: This information and picture are from the F4U-1 Erection and Maintenance Handbook and was sent to me by Lex Cralley.
Lex recovered a full scale Brewster built F3A-1 Corsair (Bu. No. 04634) from a swamp in North Carolina and is in the process of restoring it.

Boy! I just have to say it is amazing what information can come up here! I have been kinda sitting out a bit. I want to build the TW as becoming finalized here, and the tail kit (fantastic). We will all come up with something worthwhile here, no doubt! I won't post much on my TW and build on the tail, when I get there(unless informational), everyone is doing so well. Thanks to all with their ideas. I'll use some great ideas here, that is what it's about.

Chad, I think maybe add one stringer per quadrant on the fuse? Just my thought, I want to experiment with thin sheathing, as you know. I don't know how many are thinking with me. I want to do something different, yet actually traditional with the thought. It must go back to my rubber power days... -Eric

Nice going as always Richard, and others with facts. Why are we talking about "scale" surface deflection? We are two years away from the best models here. Those amongst us that are going to build and fly in months could do that with a TF? I may have missed something? This is truly not an issue for us now? Not to be a pest. Our planes must fly on a different measure than the real one and scale surface deflection really isn't important except for a static display on the flaps in my opinion.

Riddle,
If there is something I don't like is not being prepared, I hate having to look up things I will use later in the build at the last moment.

Unlike all of you guys in the USA, I have to plan well ahead to get all the stuff I need in time, thats why I am already ordering the RDS-system for the ailerons.
It is available in 2 versions, one with a 45 degree bent and one with a 32 degree bent.
The reason I need to know the max. deflection is because I would need a much higher-torque server for the 45 deg RDS, so if I can avoid that I will.
Looks like the 32 degree will do just fine.

I know I will probably not fly the Corsair with scale deflections, but I want to have the ability to use scale deflection by licking the dul-rate switch on my transmitter.
It might earn me some extra points with the scale-judges.

Cheers,
Danny "Remklep" Busch

P.S.:
For those interested in the RDS-system, a pdf explaining the system with building instructions can be downloaded here: [link=http://www.genie.rchomepage.com/FILE%2006,%20ROTARY%20DRIVER%20SYSTEM.pdf]RDS-Rotary Drive System[/link]

For those not wanting to build it themselfs, like me, it can be ordered here: [link=http://www.irfmachineworks.com/rds/]irfmachineworks - RDS[/link]

I here ya Danny. I don't think the judges will give you any points for scale surface deflection though.

I am thinking ahead as we all are, too. This should be a great result here!

Edit: Danny, sorry not to know how difficult it may be to get products there. Shipping isn't cheap here, so I sympathize. You are closer to my Laser engine maker though. Isn't there an Aussie here somewhere? That is remote.

Alright gentleman, I'm back and ready to get back to work on Corsairs! I ended up being in LA all week, not getting home until about 2 AM Saturday morning. I may have to go back one more time this week but only for two days if I do. I will post some pics of the job we did up there when I have some, you guys may get a kick out of it. We built a pretty slick slot car track for a vintage race car collector and installed it in the warehouse where he keeps some of his full size collection. Anyway, I need to take stock of where I left off with the tailwheel drawings and I will get back to making kits right away.

Great progress on your vertical fin and rudder Danny and I hope you enjoy your vacation. See you when you get back!

These pieces, which frame the trim tabs, are supplied for the elevators but not the rudder as they are easily made from 1/8 balsa scrap. (Which is called out on the plans)

I bought some german slot car track 8 years ago chad. I don't have a good basement to do that yet. I would build a nice N or HO train track first if I had a basement. Glad yer back, and I am patient on this tail. I'll probabably cut my own fuse bulkheads, but maybe I'll wait there if we can come up with something superior. I thought you might add one stringer in each quadrant on the fuse. I may have said that before..sorry if I am ever redundant. I am still waiting on a disc sander to round out the tail wheel parts if anyone's curious. I appreciate the comments from tom on not deforming the tube parts. Intuitive, but helpfull none the less. Thanks Tom.

Since there's now been a post on the CAD drawings for the fuse, and discussion on the stringers, I'll post about an idea I've been kicking around for some time. After doing the cockpit on my TF Spitfire, I found myself wishing that I could do away with much of the structure of the fuselage in the cockpit area. What I am thinking of is making that section with carbon fiber. Perhaps frame and sheet the fuselage as normal. Then cover the area to be removed around the cockpit with ultracoat. After that, lay up a couple of layers of carbon fiber that extend past the ultracoat by a few inches on both sides and then glass the entire fuse with .7 oz cloth as normal. Once set, from the inside, cut out all the balsa and ultracoat in the cockpit area, leaving a thin carbon shell which joins the front part of the fuse to the rear. Finally, add a couple of carbon small rod stringers in inconspicuous areas, or in scale locations if any. This will leave maximum room for doing a scale cockpit interior.

Any thoughts?

Scott


PS

I had the best seat in the house at the LA Jets event on Saturday. Watching jets fly below you is quite the sight!!!

Welcome back, Chad. Let me know if you have any questions on the tailwheel parts and notes. Nothing significant there, just a couple of very minor details.

Scott, I'm intrigued by your thoughts on the cockpit. I'll probably end up making a full size prototype of that area to work on the sliding canopy that we can certainly pass around. I haven't worked with carbon fiber at all. Would it be easier to make a female mold from the prototype and lay up the CF inside that?

Chris and I spent about 4 hours this weekend getting most of the glass cloth laid down on our 1/8. We'll probably add the flow coat of Polyester resin this week. One of the flaps is sagging a little bit, so we want to fine tune that before we button down the glass and prime. I didn't post any pictures on the 1/8 Mods thread mostly because I don't think glassing is all that interesting.

Tom

I think it is totally appropriate to talk about planning for the fuse now. Chad has done a "bang-up" job on the tail for us, and we can all take that great beginning and do with it what we please. As well, it should be noted that I don't think there was an intention to only go with what others are coming up with here. So, of course, we are not all waiting on laser cut kits here.

While some are still working on the TW and tail plane in general, we can start talking about planning the fuselage now, in force, I think.

We can consider several main versions in my opinion. One with a flush firewall mount, and one with the existing Royal type engine mount. If I am to cut my own bulkheads, I intend to incorporate some modification to include control rods, e.t.c.. I think we can also have two building techniques incorporated, namely: Half shell on the board, and jig built with full formers. For what it is worth, I am going to build a jig, and have the whole thing framed solidly in that manor. There is nothing against the other technique, but I just prefer having a unitized structure built on a jig during the sheeting process. I think it also goes with the original Royal plan, and traditional techniques for scale warbirds used to this day. We are using a traditional plan for this, and so I think it will be valuable to all to learn how that is done. You can build any old scale plan once you learn how to build a jig, and I think it will create some independance on building any future planes for all of us. The big kit manufacturers, and some plan designers, use the half shell technique, it is valid. I think it is personal preference, but, the Royal plan is conducive with the least mods, for jig-built.

Per the conversation on exotic materials for the cockpit, and central structure "tie ins" I am curious. One good thing about the Royal, and I have to mention Luke's thoughts, is that the Royal is made for a scale cockpit. This was one area where the Brian Taylor was vastly hindered. I would like to consider those recommendations. Best regards to all, Eric

I agree with you Eric. I know there are many that have not started the tail section yet, but the fuselage is the next step in the build so discussing and planning for it is welcomed by me.
I'm not sure if one fuselage build technique is better than the other (jig vs. split halves) so I am curious to hear comments on both. I'm leaning towards a jig build just because that is how I have done it in the past. I think it may be just as you say - personal preference.
Since I will have an articulated pilot, I will need to plan for the routing of the control rods either under or on the side of the cockpit and not through the center of it.
The sliding canopy is something I will add, so I am researching the design.

I made a minor change to the rudder to more closely match the full size trim tab shape.

The picture below is a Vought engineering drawing and it shows the angle of the top of the trim tab as supplied by Chad highlighted in yellow, and the angle of the full scale is highlighted in red. It's not a big difference, but just something that I noticed and want to change on my rudder.

I still have some shaping, filling, and sanding to do but I am close to adding the fabric.

Just to keep everyone up to date, I have everything for the first 6 tail kits cut with the exception of the 3/8 balsa parts. I also have to make copies of the plans and find (or make) shipping boxes. I should have the remaining parts cut and the plans copied by end of day tomorrow. I'm working as fast as I can and I appreciate the patience of those that have ordered tail kits. Those of you that have indicated that you are waiting to begin building (I think there were only two of you) will get kits first. The rest will get shipped out in the order that they were purchased. As soon as the first 6 sets are done I will immediately begin production of the remainder and, in fact, I have already cut enough of some parts for all the kits. Stay tuned...

Chad

My stepfather shot a few photos of the control surface details of the F4U-1D at NAS Pensacola the other day. I've added those 8 photos to my collection [link=http://cid-be7e1d3a4cb3f1fb.spaces.live.com/default.aspx]here.[/link] I've been enjoying the slower pace on this project since it's given me a chance to move my 1/8 toward the finish line. I'll post some pics in the 1/8 TopFlite Mods thread shortly. We've got it glassed now and are about ready to shoot primer. I'm using Warbird Colors for the first time, so currently testing paint, primer and filler compatibility on some test panels.

Tom

Two kits shipping in the morning gents. Randy and Richard, keep your eye on the mail box. The only thing missing is a copy of the picture CD because my burner decided to go on the fritz. I will burn them at work and send them out seperately. Sam, two kits should be headed your way by Thursday or Friday. The last two of this first run will be going to Glenn and should be shipped no later than Monday. I hope to have the parts all cut for the second run of six by the weekend. Thanks for your patience guys, I hope it is worth the wait.

I have completed the plugs for the vac-formed stab tips and hope to produce the first set of those in the next week or so. I'll be sure to post pics on what I come up with, good or bad!

Chad

Man, it's gone really quiet in here! Hope you guys are not all waiting on me!

I was not able to meet my goals above but I made good progress today and I have six kits boxed up and waiting to be shipped on Monday morning. There are two kits each for Daddy Sam, Tripower455, and Redr00ster. I have two more kits boxed up and ready to go except for the 1/4 balsa parts which I will cut early next week. They should ship out by Wednesday morning at the latest and will be going to grh_70 and James Andrews. That just leaves one more which is for RustyPep and I will have it done by the weekend.

Joe Middlemiss, Ridde4U, Rocketman612, and Saramos have all expressed intentions to purchase kits and I will accept those orders any time you guys are ready. However, I will not be taking any more orders beyond those at this time EXCEPT for guys who are on the current build roster. I really need to move on to the next step in the process or we may never get these things done!

I expect to see some serious building going on when you guys start getting your tail kits!

Great work Chad!

As soon as I find some pictures that show the radius of the rudder mass-balance (the top part that extends over the vertical stab), I can finish it.
Today I'm going to start on the horizontal stab and elevators.

I have put together a list of possible engines, the sizes in red indicate the engine does not fir in a 235 mm diameter (9.25") cowl, green indicates it does.

Cheers,

I'm still bumping along on my [link=http://www.rcuniverse.com/forum/fb.asp?m=7571377]1/8 build[/link]. I'll probably go ahead and build up my empennage from the plans since I was already a ways down that path. My project will probably be an interesting hybrid of Royal drawings, Chad's bits and things I devise on my own (I'm having flashbacks to Gene Wilder in "Young Frankenstein" for some reason). Danny, thanks for the engine comparisons. That's super-helpful and saves a lot of legwork. The deal with me is that there are so few nice days in Seatlle that I will probably spend most of the summer trying to be outdoors (flying, golfing, cycling, painting the 1/8, etc) and not holed up in the shop, so I may drop behind a bit initially.

Tom

Sam and Glenn, your tail kits are on their way. Vic (Redr00ster), if you're out there, I need your shipping address! Anyone have Vic's email addy? Richard and Randy, did you guys get your kits yet?

Chad
