Now I have my F-4 ready to maiden when the Seattle weather, job demands and daylight all converge, I'm playing with a layout of an A-6 similar to Steve's F-18 and F-15. Roughly 36 in wing span, 260 sq in area, pusher layout.
I was wondering if there is enough interest for me to start a thread on progress, and keep track of the parts as I build them.
I would also like to know if anyone has already started on an A-6 design so I don't need to do my own.

Ivor,
I've been following this site for many years and there always seems to be great interest in the A6. Certainly a beautiful aircraft. Getting it to look right (very rounded) maybe difficult, but I'm sure people will follow with great interest if you post a thread.

I'll start sketching out the general details this week and see if I can cut foam next week. I have been playing with getting round shapes out of depron, and there is a real A-6 in the MoF to study whenever I need to get to details. I can always consult with the master (Steve) as well.
I'll post progess notes as I go.

Sounds like a great idea to me, too. I'd love to see an A-6 park jet! The rounded shaping of the A-6 would be a bit more challenging to do right (compared to the rather boxy F-18 or F-15), but is certainly doable. Where to put the motor might be the biggest challenge. Putting it aft would make the model really hard to balance, but while a nose-mounted motor would probably work better for an A-6, to me it ain't a jet if the motor's in the front.... ;)

Go for it!

Oh please, I am begging you to build an Intruder; it would be even cooler if you built the Prowler (the extended nose electronic warfare version). Hint, hint....

Maybe regular block of foam , hollowed out, sanded and rounded as needed at the nose? Just thinking out loud.

fuelsguy
Jan 06, 2005, 01:30 PM
Well, I have to work sometime this week, but next week I should be able to do something. So far I have the three view drawn so I can think about hoe to build it. The fuselage looks like it can be done as a typical Steve box but with a lot more rounding on the corners. I know how to do this. The nose has to be foam or a lot of depron layers. I have looked at making the nose removeable to get access for batttery etc instead of down through the cockpit area.
As far as the Prowler is concerned, I think that has to be the second version, but a relatively simple nose job.
I'll post what I've managed to get done in the middle of next week.

Ya know, being from Seattle you should build an EA-6B prowler, since we are only 1 1/2 hrs north of you on Whidbey Island. I could give you a personal tour of a real prowler, only if you promise to build me one of course:)

Setting up a pusher CG will be a real challenge. The real A6-A would settle on its tail when all of the APQ-92 and APQ-112 antennas, mounts, and boxes were removed from the radome. We had to drop the tailhook before removing all the radar equipment from a bird going into check to keep it from settling. We then had to bolt steel plates to the radar hard points so that the airframe could be towed around.

Isn't this the Interactive toy's A-6 2 Ch RTF?
Way underpowered stock.

Are you trying to do conversion? Essentially the same plane as the Hobbico free flight A6 but with a two blade impeller instead of 4 blade.

My thought would be either to use stronger battery on the stock motor or ditch the stock fan altogether and slaps two EDF40s at the back. Fits nicely and more "scale" as the real A-6 is a twin.

fly_boy99
Jan 07, 2005, 02:42 PM
Yep but here's my thought. Go 3 Channel and take out the
stock motor pushing the 4 blades and replace it with a J250
and use a 480 TP pack or maybe the 340HD kokam.

I'll post more pics when I'm done modding.

It is in the respect that my Avionics Officer In Charge (OIC) took it (he was the pilot of the 5th plane in formation). It was taken over Eastern North Carolina near Cherry Point sometime in mid to late 1969. The only times I got to fly in the right seat were on either cross countries or check flights and there were no other aircraft around. I had a seat card for Martin Baker seats so I got to go up occasionally.

When my grandfather died in 1967 I got emergency leave and my Sergeant Major got me a ride to New York in the back seat of a F4B Phantom II. That was a trip and a half, it was one of the Bennies for being in the Air Wing. I had wanted to get into a Phantom squadron, in fact most of my Avionics and Fire Control training had been with air to air systems like the Phantom's. In the 11 weeks we were in Fire Control School we saw one classified movie on the A6-A Intruder and that was our only exposure. When we hit the wing, every Marine in my class went to A6s. So we all had to go to additional 10 and 12 week NATD schools at NAS Oceana and NAS Whidbey Island. I was fortunate enough to get to go to both training detachments prior to deployment to Nam in 1968. These ugly little planes grew on you, I never regretted being in an A6 squadron. We used to call them pregnant tadpoles and say that the AW stood for All Work, All Week. It actually stands for All Weather.

In the 4 years I was in the Corps I was assigned to only two A6 Squadrons; VMA(AW)-224 (WK) The Bengals while stateside (seen in photo), and VMA(AW)-242 (DT) The Batmen while in Nam.

Hi folks,
Here are some shots of progress. I started from the small scale three view in the "Russian Site", blew it up to the scale I needed at the local Kinko. I then figured out fuselage cross sections and layed out the patterns for the Depron. I cut out the patterns on 1/8in. hardboard so I can cut multiple pieces if I need them. The fuselage I built as a box section, with a few formers to hold it in shape. To get the rounded fuselage I cut away a 45 deg slice fron one edge of the box, and glue a new depron stripe down over the slot. Repeat four times and you have a octagon fueslage.I then cut and sand the octagon to a rounded shape.
I cut the inlet area up front to give the classic A-6 chin. more work needed there. Then I couldn't resist doing a quick put it all togehter with toothpicks.

More later

I plan to install a pusher prop with a shaft drive. I have some shots on the F-4 thread of my Black F-4. It uses similar approach. see attached shots.
This puts the motor up to the CG and then the battery does the rest. On the F-4 I have a 1100 Li Po battery at the back of the cockpit area, so I have a lot of room for CG adjustment.

I figure if I can get this one worked out the Prowler is a fairly easy jump. Add a nose section and that wonderful tail fin. I need to learn how to vacuum form cockpits then I can do the inside of the cockpit as well as the outside.
There must be some nice color schemes out at Whidbey NAS.(hint, hint). I have been looking at the A-6E out of Pax River with the red wing tips etc.

Any timeline on plans yet? I think this is one sweet looking jet. I have always wanted to build the Intruder but have not seen one at this size that is even close to scale. I can't wait to see how it progresses. I'm stocking up on Depron now in anticipation of building one of these. Pics look great. Keep up the good work. :cool:

Plans, I'm starting into CAD after a long time away from it. I have sheet with all the shapes marked out and I plan to have Kinko shoot it as a ful size PDF file. This should work for most people, unless they have a laser cutter under the work bench. Since I'm in the build and learn stage, I want to get a bit more of the detail stuff done on my model so I can make any last minute changes to the plans. I should be through with most of that in the next week.

Progress report:

Spent way too much time cutting and sanding pink and blue foam, but the fuselage is beginning to look like an A-6.

Had to go and buy "Flight of the Intruder" just to see the belly on an A-6 with the gear up. Gear down it hard to see the lines.

I plan to add motor/drive shaft and servos over the next week, but I have a lot of work commitments so it may have to slide.

Thanks guys, it all comes from Steve's park jet power to weight ratio and the magic 250 sq inches.

Finally found some time to paint and decal the A-6.
Spend a week or so messing around with drive system, I switched from a 5mm O/D carbon tube to a 3/8 in O/D Aluminum arrow shaft as the drive shaft.This required lots of fiddling with adapter pieces but it seems to be working OK now.

First flight sometime this week if the weather holds up.
Yes Steve, I know you fly then paint, but I can't resist painting once the plane is done.

Feb 08, 2005, 10:58 PM
Steve,
I did a quick weight check. All up, ready to fly with a 1100 Lipo battery it came out at 22.8 oz, which includes a lot of paint as I tried to cover up all the various shades of pink and blue foam. This goes with a wing area of 268 sq inches. Interestingly, to get the CG about right for a first flight, the battery ended up sitting on top of the wing center section, (must be the usual heated center wing tank), so the shaft drive gives a lot of room for playing with shrt nose long tail airplanes. Rhodri's seen the latest shaft drive in action so he can fill in details if you see him sometime.

Kscbob1, yes I know the refuel probe is missing. I want to get some time on it first. The first upsidedown low pass will take it off anyway. In the Seattle area the A-6 run through the mountains and fequently roll upsidedown to keep positive g as they go over the pass. Very impressive if you are looking down on them.

Feb 10, 2005, 09:29 PM
As long as they keep positive G's. I worked on the A version and the J52-8 engines had gravity fed oil pumps so they couldn't stay inverted very long. When armed with the bullpups the pilots had to learn to fire them as they entered a roll and then joy stick them onto the target while inverted and continuing the roll. You gots some healthy mountains out there, I was stationed at the seaplane base portion of NAS Whidbey Island while attending A6-A APQ-112 Track Radar School back in the winter of '68. Loved to go down to Deception Pass to see the Navy and Coast Guard run their DEs and cutters through.

Couple of answers:
bibeflyer, I tried the russian site without any problems this morning, downloaded a meteor three view.
Cass, Shaft drive: I tried a few variations along the way. I started with a 5mm carbon tube with 3mm steel shafts glued in each end. the front end mated with the motor via a short coupling, I tried both rigid and flex couplings. The aft end ran on a 5mm ball bearing support, with a prop adapter on the 3mm shaft. The problem I had with this was the out of balance loads causing bending of the shaft on start up until the speed was above critical. (think of a washing machine spin cycle start up).The loads would cause the carbon to split at the shaft end and the prop would become loose. After several tries, including multiple u-joints and multiple shafts, like a car drive shaft, I ended up with a simple layout. I used an aluminum/aluminium arrow shaft, 3/8in o/d and made a couple of rigid connectors. the front one mating with the motor shaft and the rear one became the prop adapter. I used a delrin plain bearing at the rear end. I aligned the whole thing by installing the rear bearing loosely,using a spare arrow shaft and adapter to hold the motor and mount (I use a GWS like 10mm square rod) aligned with the rear bearing and then epoxied the motor mount into place. That way I minimized any out of alignment. I then epoxied the rear bearing. This seems to work OK. I'll post some pictures this evening or tomorrow.

Gromitvt10 - How often do your birds go to PAR? You'ld think that after over 30 years the Navy could spring for a little fresh paint for your birds. Oh wait, how did that little ditty go - "If it moves salute it, if it don't paint it." :) I guess your birds are moving to fast to get painted. :) When I worked on them we were complaining about getting all of the Navy hand me downs. Our airframes were only 4 to 6 years old at that time and they were getting to look pretty well worn. I can't imagine how they would look after forty years. My hat's off to anyone who's job it is to fly a forty year old airframe on a day to day basis.

Well, since it's been nice in Seattle for a few days my flying skills have gone up enough for me to be brave enough to maiden my F-18 on Monday and the A-6 today. Both came home alive, anthough the A-6 now sports a lot of grass stains on the belly. The A-6 flew nicely, right out of a hand lanch. Roll control was just right, but it was a little sensitive in pitch. I need to play with cg and throws to get it right. It did look nice in the air. I'll try and get some video/stills this weekend.

Although not completely to scale, until I get done with it, the www.kress-jets.com Intruder provides a good start toward both the Intruder and Prowler with either twin DFs or a single larger DF. Further the model can be "enlarged" to accommodate the larger electric DF along with real landing gear. As those who have any hours in or around these ugly beasts know, they can accommodate a lot of internals.

May 18, 2005, 12:45 PM
Beaner you sound like an ECMO, scary...lol I've also got a Kress jets A-6, what DF and batt are you using? Haven't started mine yet, waiting until i get down to Navy Post Grad School in Monterey. But i do want to add landing gear, what are your plans for that??

May 18, 2005, 01:05 PM
I was both a bombardier / navigator (in A-6s);hence, Beaner,and an ECMO, but even more frightening, I was an EWO in EKA-3Bs. I will be adding kress-jets RK-709 with the axi flow motors as they each develop over a pound of thrust each. They are adding the appropriate axi motor to the RK-720, which will have increased thrust for much less than using the HB motors. When one considers the real-life thrust to weight of the P-8s in A-6s and P-408s in EA-6Bs, the use of the kress-jet solution seems quite appropriate. I am receiving the kit next week, and will start modifications almost immediately. I have drawings from GAC of the EA-6B that I've transferred to "plastic" drawing paper and will be going from there.

Understand the Prowler Symposium is ongoing now.

Beaner, i was unaware that BN's were called that. Ummm learn something new everyday:) Yup the EW symposium is on going, i went to all the briefs that interested me yesterday, plus i got to help set up and fly the EA-18G sim, pretty kool!!! Yeah the Prowler thrust to weight ratio is pretty sad, but she can get up and go when she needs to. Flying low levels through the mountains is still a blast!!! Are you putting retracts on yours? Please keep me informed of your progress, i may try to convert it to a Prowler.

BeanerECMO
May 18, 2005, 07:21 PM
The problem with a lot of EA-6B pilots (and ECMOs who have only been in Prowlers) is that they really don't keep in mind that they've taken off with a load of bombs (pods) and will be returning with almost the same load and drag. Also, as you are keenly aware after hours in the Olympic and Okanogan OPAREAS, the Prowler is quite nose heavy, and this is really evident when doing approach to stall maneuvers. Many of the junior and mid-grade pilots with whom I flew took quite a bit of umbrage at my (a lowly ECMO) advising them of these characteristics, because "I didn't know what I was talking about". Well, one of the pilots with whom I flew, and then advised the CO I would not fly with again, made a huge crater in VA on the way to the ship taking all on board with him. LLs are great, both in the Prowler and Intruder. When I flew with my skipper, I would operate the radar and do radar navigation to try to maintain the skills I learned while a A-6E Development Project B/N at China Lake and with a CARGRU staff. Of course, the skipper was the backup to my navigation, and I embraced the challenge. Flying around China Lake and Fallon was especially great throught the Sierra Nevadas and over the dry lake beds. There were few EA-6B pilots with whom I felt comfortable, because I really never knew what they were going to do and many were quite uncommunicative; while flying in A-6s, there was an immediate bond of trust both ways.

I'll let you know what happens with the model.

Well. I now have a CAD set of plans for the A-6. I finally sat down an re-learned some of my old CAD skills, and used to A-6 as a practice task. It ended up as three sheets, 36 by 48 inches. I need some advice on how to get them posted.
Is it best to convert them to PDF and zip them or what?

What extension do the files have? Are they AutoCAD compatible? You may think to post them both in both the original file extension and as PDF. What is the file size? You may also consider to have each sheet as a separate file. I know I would be interested in the original file extension (if it is AutoCAD compatible).

Hi Ivor,
Posting PDFs is the best way to do it, since that allows anybody to open them. To create the a PDF, just download and install a PDF utility. My favorite is PDF995--it's free and works well with not only my CAD program but all of my programs. It functions as a printer driver, so after it's installed you just open the Print dialog box, select PDF995 as the printer, configure the options, and click print. It's available at www.pdf995.com. The free version is advertiser-supported (though it just pops up one ad), or you can pay $10 to get the non-advertiser version.

i'd say both PDF and DXF(dwg? the original format). i've been working in cadd work again so i'd like to see it in that format. :)

Well, here are the DWG drawings for the A-6. They are not super as I just don't have the CAD skills yet, and lots of details need to be decided by the builder. They should be a good foundation for a model. The photos of my build process should help as well.
I'll try to answer questions as they come up. Hopefully the Zip files will unload into DWG files for reading in AutoCAD or similar programs. I'm using DesignCAD and its converter to DWG files.
If anyone can help guiding me through converting these to PDF, both big and tiled, I would appreciate it. I can get to Acrobat but haven't looked at how to do any of this yet.

Question: should these files be moved to the free plans thread?

As an aside, I downloaded the freeware WinTopo, which does a good job of converting raster images to vector/DWG images. I took the A-6 drawings from the russian site and converted them to vector images and started from there.
The russian drawings are very detailed so they end up as big files, but simpler three views would be a great starting point for a model.

Thanks for the tip on PDF file conversion.
Here are my sheets as PDF's

I realized that the PDF's are sized to 8.5x11, so I went back to get full size ones. this was definitely a challenge! Here they are, I think.

Found a couple of minutes.
Here's the side view with the prowler nose added. You can extend the fuselage sides, top and bottom to match.
I would add a bulkhead to support the longer nose of the prowler.The top view is just a parallel extension of the A-6 to add the extra cockpit space.
Hope this helps,

Ivor

thanks for the great plans! i keep thinking i want to duct this thing, but its going to be tight with scale inlets!

fuelsguy

Synwpn,
I went through the same thought process. The inlets are small and the exhausts are really small.Even if you run one fan there's not enough flow area.
I did think about doing something like an old Jetex model where the exhaust was in a trough under the fuselage, but didn't go anywhere with the idea. You might want to think about that.

I took a few serious looks at the plans, but am I right when I say that I first need to make a box from depron, and then put some layers on the side/top and then sanding it? I actually find the plans somewhat unclear (for my expercience).

Furthermore, it's a sweet and original plane to have as a parkjet!

Hi Dave,
The short answer is yes. Make a box fuselage then take a long very sahrp blade and slice off one corner at about 45 degrees, thne glue a strip of depron over the opening. Repeat for the outher three corners and you have an octagon shaped box that you can sand to the fuselage cross section. Forward of the wing leading edge you need to cut a lot of depron off the lower half of the fuselage so the diagonal depron strips from the sides of the fuselage between the inlets. Check my build photos, it should become clear (hopefully). On mine I kept the "octagon" section from about the LE of the tailplane to the LE of the wing. on the aft end of the fuselage the section is boxy enough to use the original box, and forward of the wing LE you do an instantaneous transition to the triangular fuselage. The step change from octagon to triangle is filled with inlet so you don't see the step.
Hope this helps,
Ivor

It's still around, currently sitting with the rest of the pusher jets I've built over the last year. I had to take the motor out for another project, so I'm thniking about trying it as a PPS slope soarer when the weather improves.
