Maiden Flight 4/3/2014

Sketchup Files-  Zoom out on the plans and you will see  other parts to the plans which help in construction.   The are for the 78" plane but can be easily rescaled in sketchup to any size.   If you build and fly one please send me pictures and videos.  I would love to see them.  I would be happy to help with any construction issues...    jvlupo@yahoo.com

was for 64"WS put I enlarged plans to 74"WS. 

Hi Gang,

Just about finished with this massive 76" wingspan C-130J.  Big jump going from my cargo twin engine plane to this four engine monster.  Used plans of old control line C-130 I got off the internet, added some length to the fuselage to make it a C-130J and scaled it up from 48" to 76" WS.  I just scaled it by enlarging PDF file and printing them.  Constructed plane with FFF and DT foam internal framework and skinned plane with paper stripped DT foam. 

 

 

Wings were constructed using a modified Flitetest technique with DT foam keeping the scale airfoil which most interestingly has thickest part of airfoil at 50% for best lift.

 

Powered by 4x 2822 1450kv, 4x 8x3.8SF  and 4x 20A speed controls.  Should have over 600W of power.  Controls are throttle with differential thrust(R/L), Flaperons(ailerons/flaps), elevator, rudder and Bombay in midsection.  Kept everthing light and sound be fun to fly.  Goes against my usual mantra "quick build" but it sure is a cool looking plane.  All that is left is installing some servos, adding the decals and some other details. Just have to wait for the the snow to melt in NH to try this bad boy. 

 

 I am trying to convert my modified paper plans to sketchup and then to PDF for everyone.  I will try to post as quick as I can.  For now here are the main wings.

Here is what the interior of one og the nacelles looks like.

Nacelle plans- 1 page

Just finished bulk of the fuselage section. REMEMBER- I overbuilt the internal structure of the fuselage(see my pictures). Just reinforce bulkheads as needed around wing area, possible creation of bomb bay or rear door, and area for battery, esc and receiver below wing. I created a large shelf there. I just wrapped the fuselage in dollar tree foam with paper stripped of one side and pre-curved, leaving the bottom(flatter part) of the fuselage for later covering.

Happy to answer questions-  please post build pics!!!!!

 

 

 

Here is adaption for a 64"WS C130.

1. "use nacelle plans- 1 page" and enlarge 1.66 times.

2. "fuselage bulheads- 1 page" and enlarge 2.6 times.  Then use dimensions on "64.fuselage cross sections" and "64.fuselage cross section skew" for construction

3. main wing use "64 main wing" as dimensions for construction

64" main wing pdf

 Main fuselage basic construction showing horizontal and vertical supports.  Probably overkill but its gives support and easier to cover with the foam.  The fuselage has length added to make it a C-130J

Boxes built in lower mid section: forward one is small bomb bay and rear box is support for main wheels.  I reenforced tail of fuselage section with 3/16 square dowels for added support.  They also stuck out a few inches to secure to the horizontal stabilizer later.  Not really sure if they were needed.

I'm speechless! This is my one of my favorite planes! The other one is the A-10. Where did you find the plans? I want to build one of these. How hard was it? If you're willing, I would love some more details about the build. Do you have experience building balsa models? I'm trying to guage how difficult it will be for me to build one of these, as the only experience I have are the scratch builds designed by FliteTest. Thanks for sharing!

That is Beautiful! My dad used to fly in C-130s and I've always wanted to make one but my piloting skills are not very good at the moment. (need some practice I'm still a beginner) I am though working on a design, the Brewster F2A Buffalo. I have the v1 plans up on the forums but have yet to aquire foam board to test it. Some day I will scratchbuild a C-130.
C-130s are beautiful though great job!

Here are the plans that I used as a guide. They were old balsa control line plans from the 1950's. I printed the plans from the PDF file and increase wingspan from 64"to 76" by increasing size in print window and tiling the printout. I pretty much overbuilt the fuselage and would use less internal structure next time. I did add length to the fuselage in front and back of the wing to be consistent with the longer fuselage of the C-130J. I will start on sketchup plans for the plan as I have most of the design on paper. I was designing as I was building. Wing was classic Flitetest wing creation which worked well.
Waiting for the weather to get a little nicer here in northern NH so I can fly it.
I can start on the fuselage plans or the wing whichever you guys want first. It shouldn't take that long.

To build a simpler version here is a link:
http://aviationshoppe.com/airplane_plans/download.php?file=906
Just make a flitetest type wing or KFM airfoil with a round or square fuselage with solid foam carved nose.

Here are the plans I use to adapt to the plan. Note- these plans are for 64"ws. My plans will be for 76"WS.

Hi. I would just like to say great job. I did something similar with an old set of Goldberg plans for a big cub. I've flown it once and it flew great. It is a little challenging but the building process for little air planes does work well in a larger format. By adding a little balsa it's pretty easy to do. Keep up the good work.

Beautiful job on the C130. We have 2 of them flying over our house all summer because they do training such as dropping of supplies by means of low passes, kind of a touch and go thing. The C130s fly out of Pittsburgh. Thanks for the plans, it will be a challenging project for later in the year.

I was surprised how easy it was to build. Longest time was the planning and thinking about the conversion from balsa to foam. I was adapting and changing the plans as I built it, as you can see from the nacelle construction. Once I figured out how to construct it, build time was very short. Soldering all the wires and connectors took the longest time. Especially all the Y connectors for the batteries which gave me the most trouble.

I hate to even ask after you have already shared so much of your hard work on this project, but is there any chance you might have non-tiled versions of these plans? I usually send my plans to a print shop to cut down on the time it takes to trim and tape the tiled plans together. As long as one of the dimensions of the PDF document is smaller than 36 inches, they can print it on a single sheet.

Lupine,

When I saw this article, it made my day! Actually, it made my whole week! I'll probably have to scale this back down to a 64" WS, or I won't be able to transport it. Hmmmm, maybe I need to buy a bigger vehicle. This hobby is getting out of control!

Jaxx,
I know the feeling. This is the biggest plane by far I've ever built and this monster barely fits in the wife's minivan. I am still trying to figure out all the printing/pdf quirks of sketchup. Not exactly sure how to make real size print in single pdf yet but will work on it today. But for now will post single page plans of same. If you want I can try to convert all drawings to 64"WS. It shouldn't be that hard.

Lupine,
I'm grateful for anything you're willing to do, and I know it takes time and effort, so I'm happy to wait as long as it takes for you to figure it out. A 64" WS version would be great, if you can find the time to do it. I so badly want to lean SketchUp, but I cant seem to find the time. Once you figure out how to do the real size print on in single PDF, that will be great. That makes it so easy to get these plans done at a print shop. It also allows me to support a local business. Thanks again!

Joe,

I can't thank you enough for taking the time to do the conversion. I will probably be using DTFB for the bulkheads, as I can't seem to find any of the FFF locally.

lupine on March 31, 2014
Jaxx,
I built the C-130 90% out of DTFB. Not sure why I actually used some FFF in the plane???? I like DTFB better because its much stronger than FFF. Now that I know how to treat and paint the DTFB- its my favorite construction material.
Home Depot and Lowes carry FFF but it is sometimes hard to find and it is so "wavy" its almost unusable. I found a great supply a Harvey Building Products: which supplies local window and door companies in our small city of 100K. I imagine if you call around you will be able to find a similar supplier in your area. It is a supplier only and does not sell to the public but I just walk in and tell them about using it to build RC planes and they want to hear all about it, AND give me a discount. The stuff is PERFECTLY flat and easy to build with.

I am in the proccess of building a 48" model of a Grumman Sky Rocket. I got a plan of Dave Rees ff model and enlarged it. I am building of dollar tree foam using the mortis and tendon joints for the fuselage with foam formers. The wing is folded over a foam spar. I removed the paper from the inside of the wing skin and with closely spaced grooves, I got a smooth airfoil. The wing is in 3 sections and joined with alignment spacers of foam.The nose is laminated foam with the paper removed as will be the engine cowling. I am removing the paper and covering with colored plastic tape which makes for a strong build. Removing the paper reduces the weight over 1/2. After I finish and weight it I can order the motors and gear. Thanks for the idea for the removable landing gear.

If doing the 64" version use dimensions of the original control line pdf plans that I have a link to in article. If building the 76" version that I built, enlarge 64" pdf version by 116%(1.16). That increases size from 64 to 76". Hope that answers the questions. As you can see from the maiden video she flew line a dream!

Did you remove the paper from all of the DT foam you used in this build?
Log In to reply
lupine on April 7, 2014
When using DTFB for a structural component, I leave all the paper on and this gives enormous strength and no flexibility. When using DTFB and curving it around the fuselage and wings I take the paper off on the inside of the curve. The paper is left on the outside. This gives the DTFB ability to bend easily and still have paper on the outside. I pre curve all pieces to make construction easier. Usually on the edge of a countertop. ie the fuselage covering is pre rounded to a tube and bent in place so it just slips into place over the fuselage framework before gluing. Does that help?

Wing is bent:constructed like they do in flitetest models and also like the Armin wing in the video:

I live in Bedford and fly at the soccer/lacrosse field by the farm on Joppa hill road (huge area).
The c-130 is an easy build, if you have built a FT plane before. Nothing new in the construction, its just bigger. The hard part was making all the curved surfaces fit together as I was building it and making the plans. The plane flies incredible as you can see by the video.

Hi Spetnazer,
After the aircraft was done I made the build log. My friend suggested I do the build log after I was done. Sorry but I would have taken more pictures and video if I would have know from the start I was going to do a build log. This was the first build log I've ever done. I made the plans digital after the construction from my paper adaption of the old plans. I would be glad to explain or make a demonstration video of any technique that I used. I will make sure it is more thorough next time. My second build log was a little better for the twin engine Goliath.

I built the C-130J because couldn't find anyone who had an easy version out of foam. The wing is pretty straight forward and the fuselage I tried to simplify by all the diagrams. Cut out the parts, glue then wrap. I'm still waiting for someone to start one so I can help them out. I will try to make some videos or more pictures of construction.

Jaxx,
First print out plans of the original control line model plans for reference and the print out the two diagrams of the 64" fuselage with dimensions (side and oblique view). Print out 64" fuselage bulkheads plans.

cut out F3, F10(x5), F12, F13, F14 and F15.
cut out all the little pieces connecting the bulkhead together using fuselage dimension diagram.
put bulkheads together as in picture*****(make sure straight, and top of all bulkhead pieces on same level)

Look at picture of my bulkhead construction and cut and place horizontal pieces between bulkheads giving a floor between bulkheads. These rest on top of vertical pieces between bulkheads. also look at pictures to support where landing gear go and where the wing is placed. These are all internal structures for support and likely overdone by me. As long as everything lines up you can do anything you want. I found that wrapping it in foam gives fantastic support even without the extra internal supports. Let me know if this makes sense and how things are going....... Joe

I have the original control line plans printed now. I picked up some Elmer's foam board to make the bulkheads, since I can't find any 1/4" foam at the hardware local. stores.

Jaxx,
Are you in the US? Dollar tree stores carry foam board that is very light and strong. Regular foam board (ie elmers) from craft and other stores is quite heavy and the paper is very hard to get off. That or you can construct entire plane out of fan fold foam (FFF). FFF is Found at building supplies places. Or even Depron, which is hard to get in US. Just a worry that using regular foam board could make the plane heavy.
Joe

Jaxx on April 22, 2014
Yes. I'm in the US. I was only going to use the Elmer's foam board for the bulkheads. I figured the bulkheads should be more rigid since you used FFF for yours. Do you recommend using DT foam board for the entire build? I have tons of it (I buy it by the case), so that wouldn't be a problem.
Log In to reply
lupine on April 22, 2014
You won't find FFF at a local hardware store. The FFF is used as an underlayment for exterior siding. You can find it at lowes/ homedepot/ menards/ 84 lumber....... or any building supply warehouse. Even window/ door / siding companies or suppliers carry it. I bought mine from a wholesale window and door supplier in Manchester NH and it was perfectly flat and not wavy like the stuff in Home Depot or lowes.
Joe

Jaxx on April 22, 2014
I believe the availability of the 1/4" FFF is dependant on where you are in the US. None of the Lowes stores in my area carry it. I can get 1/2" and 1" sheets, but not the FFF. I will try to find a local wholesale window and door supplier to see if they carry it. I have some Depron too, but if I can do it all with the DT foam board (much cheaper), I would prefer to do that (at least for the first build). The Depron goes for about $9 a sheet. Fortunately, there is a supplier about 5 minutes from my house, so I don't have to pay for shipping.

I had the print shop print the 1 page bulkhead plans at 260%. The length of the horizontal dividing line on bulkhead F10 is right at 7.25 inches. I wonder if their equipment is scaling it differently. I will talk to them to see if there is a way to measure the line on the F-10 bulkhead when they scale it, before they send it to the printer. That way, I don't have to pay for ones that print incorrectly. This is the number one plane on my build list, so I will not rest until I get this right. I will be happy to take pictures of the build as I go, and post them to rcgroups. Again, thanks for all your help with this.

Jaxx, Sorry about the trouble.
The 76"WS F10 bulkhead is 7.5" wide. If you scale it back to the original 64" size in the control line plans by PDF that bulkhead should be 6.5". I confirmed by both downscaling 76" to 64" on the sketchup plans and also mathematically
(74"WS +2"tips/64'WS) = (7.5" F10 for larger WS/ X" F10 width for smaller WS)
solved for X=(64*7.5)/74= 6.49"

I verified this on my computer by increasing the printing size of the 64" bulkhead 1 page PDF by 260% and printing in tile mode. Not sure whats going on? I can post the sketchup files in 64" if that would help. I'm still learning sketchup and not all that great at printing pdfs. I cannot figure out how to make one page PDF in actual size yet. Make sure to print out the original plans of the 64" control line plane for referencing. It helps a lot. There are some other templates I have which helped a lot (ie how to cut fuselage to fit wing). I would just work on the basic fuselage and main wing first then we can tackle some of the details.

I have to say this is the best plane I ever build and is awesome to fly. We can figure this out. It will be a fun build. Should be a lot easier than when I did it. I made it up as I went along.

I'm still working on the 64" C-130 project, just got delayed momentarily. Had a personal situation come up, but trying to get back on track. I will be contacting you with questions. Thanks again for all the help.

Hi Jaxx,
I was wondering if you just gave up? Good to hear your still on the project. I will gladly answer any questions and post more diagrams and plans as needed. Been flying the C130 a lot. Have about 12 flights on it. People always stop, watch and take pictures when I fly it at local lacrosse/ soccer field. -Joe

Not at all. I've been trying to find plans for a C-130 for quite some time, so I couldn't be happier to have found your project. My wife's car was stolen a few weeks ago, so I've been dealing with that, and I recently changed jobs, so there has been a lot going on. I am finally getting back on track with the C-130 project, and will keep you updated. Thanks again!

Hey Joe,

Amazing work. So amazing I would like to build one too! I don't have enough room in my house for the full size though. I am planning on scaling it down to maybe half size or so. Also, do you think you would be able to send me a copy of the Sketchup files for this build?

Was looking for any RC version of the C-130 and came across this. I am simply amazed and humbled that you would put this detailed of a plan online! Thank you very much.

Hi,
I completed the plane first and then determined the battery layout. Luckily the COG was almost perfect location without any batteries. With my 78" plane I use 2x 2200mah which gives me 20-25 flight time. The batteries lie alongside each other lengthwise and parallel to fuselage. Most forward part of battery is at leading edge of wing. They lie right under wing. That gives you a COG that is 25-33% of cord. Can use single battery if you want and makes no difference. Easy since didn't have to make compartment for battery in front of wing. Depending on construction will determine your layout. ie wheels/apron/motor/esc/paint. The rear part of fuselage has to be reenforced with square spruce dowels as it is too weak with foam alone. I will send a picture of layout when I get home, currently away on vacation.

Hey Joe, excellent built! Thank you for posting.

I am a volunteer prop builder with our theatre-on-ice-team, the Space Coast Hurricanes in Rockledge Florida. We plan to built one of these models for an ice skating compettion and it does not have to fly. Just strong enough so the kids and the ice conditions wont destroy it and light enough for a couple of kids to carry it while skating. We are planning to built the 64" wingspan one. Can we pick your brain now and then for clues?
For starters: is the blue foam 1/2"? and do you cut it with a foam cutter?


Thanks, Rob Oudejans

Hi Rob,
I'd be glad to help. The entire plane can be built out of dollar tree foam board(the foam with paper on both sides that is 20"x30"). All else you need is a piece of styrofoam for the nose(old cooler), a hot glue gun, a long wooden dowel and a roll of clear packing tape. I used a single edge razor blade to cut it out. Thing about dollar tree foam board is that is you have to rub on some polyurethane onto the foam board before you paint it. If you paint dollar tree foam board with out treating it-all the paper peels off. Let me know what ever help or guidance you need. You can make a real simple version. Just enough to look like a c-130 and strong enough to carry. You can email me at jvlupo@yahoo.com
Best Regards-Joe
