Descripción del modelo 3D

EDITAR - 20.09.2021:

Nueva pieza frontal de la nariz con escotilla de almeja para hacer el acceso a una batería o lo que quieras poner en la nariz. Usa un tornillo M3 para mantenerla cerrada.


EDITAR -22.07.2021:

Añadida una nueva carcasa EDF que puede utilizar el motor HET sin disipador, ya que el disipador puede ser difícil de encontrar ahora. EDF-housing04-Noheatsink.stl

Soporta el motor hasta el final y tiene un hueco para que el aire pase alrededor del motor. Debe ser impreso de un material más resistente al calor que el PLA, y eso va para el impulsor también porque la falta de un disipador adicional puede elevar la temperatura del motor y del eje hasta donde el PLA comenzará a ablandarse.


EDITAR:

Añadido un nuevo canopy que es una pieza principal en lugar de dos para imprimir en una impresora muy grande (además de la pieza del parabrisas delantero). Los nuevos archivos son Canopy01-onepiece y canopy02-onepiece.

El humano no está incluido.


Especificaciones:

Longitud: 1858,5 mm

Envergadura: 1451 mm

Peso total: 7,2 kg (prototipo #1), 8 kg (prototipo #2), 7,5 kg (prototipo #3)

CG: 83-103 mm desde el borde de ataque en la articulación del ala con el tren de aterrizaje en posición elevada. Hay una protuberancia en la parte superior de cada superficie del ala para indicar la posición segura de 83mm/25% del MAC. Subir o bajar el tren de aterrizaje no debería suponer una gran diferencia debido al bajo peso del tren de morro. El prototipo se estrenó con el CG en aproximadamente 90 mm. El CG de 103 mm ha sido probado y vuela muy bien.


Lanzamientos de control iniciales:

Elevador: Arriba 18 mm / Abajo 16 mm

Alerones: Arriba 20 mm / Abajo 15 mm

Timón: 15 mm / 15 mm

Utilice un 30% de exponencial en todas las superficies para reducir la sensibilidad del centro.

Las notas de construcción y la lista de materiales se han movido al archivo de texto BuildNotes.txt debido a las nuevas limitaciones en Cults cuando actualicé la página 17.11.2020.


Parámetros de impresión 3D

La mayoría de las piezas deben imprimirse con un solo perímetro de 0,4 mm y sin relleno por supuesto. Las excepciones son las piezas de bisagra, las piezas pequeñas y las piezas del tren de aterrizaje, que deben imprimirse con muchas paredes o con relleno sólido.

Las carcasas de los FED deben imprimirse con un 100% de relleno y con tres perímetros.

El impulsor EDF debe imprimirse con 6-8 capas superiores e inferiores y 6-8 perímetros y 0% de relleno.

Las partes del fuselaje necesitan 3 capas inferiores y seis capas superiores en su mayoría.

Recomiendo imprimir el Nose03 con dos perímetros para los primeros 120 mm para que los soportes del engranaje estén reforzados.

Fanrail01 necesita ser impreso sólido si planea taladrarlos para un EDF del mercado de accesorios.

Maingearmounts01 debe ser impreso con seis perímetros y veinte capas superiores para dar algo para los tornillos de montaje de retracción para agarrar en. Las capas inferiores pueden ser solo cuatro o cinco. El relleno no es importante. No se utiliza el relleno.

El tren de aterrizaje01-02 debe tener ocho perímetros de 0,4 mm, doce capas superiores e inferiores y al menos un 50% de relleno. Lo mismo ocurre con las piezas del tren de aterrizaje.

Hello, what are the airfoil profiles used in the model (wing, tail, rudder)?

The wing is Eppler 205. The tail surfaces are not any specific profile, just my own symmetrical profile plots.

Hi everyone downloaded this Beauty;-)! Has somewone a good Cura Profile for LW-PLA for Anycubic Chiron, trying the Planeprint and eclipson Profiles now out? Thanks

Buy 1 time per 1 print, right?

You can print how many you want. You get the files to use over and over if you need to.

Hi, I bought the L39 Files and the Design looks great! I would like instead to print all parts, printing negative Molds of the fuselage but i'm unfortunately not skilled enough with fusion 360 to join the parts together to get one large piece, may you provide me the fuselage as one piece?
Please let me know what it will cost and thank you for your feedback
Best Regards

Hi.
Sorry, but I don't have a single part fuselage in CAD. I designed it in multiple parts. I don't have time now to make it a solid single piece as it was made for printing from the ground up.

Thank you for your feedback, ok, if I want to print it with LW-PLA, does it has to be redesigned because of stringing with lw-pla or is this all about slicing? thank you

Too bad, this one won't fit on my printer after buying it!!

I've printed this on a Prusa MK2S. I split some of the parts into 2 pieces to fit on the build plate.

I have no plans for a smaller version. If anything I will make a bigger version.

Will you make an 80mm or 90mm version??

Will you make an 80mm or 90mm version??

If you want just the frames you need to print the regular canopy parts and cut the glass out. That's what I did to the one I did with separate glass.

Love the files, thanks for sharing! I'm working on printing it myself, the airframe is done and just working on the small bits now. One question on the canopy pieces, there's the complete pieces and the plugs, but is there a way to print just canopy frame to put clear vacu-formed parts in? Now sure what your CAD model of the solid canopy parts is like, but if it's easy to just remove that inset piece. If so, that would be awesome. Thanks!

Uhhhh, awesome plane, congratulations!!!! Wish I could make 3d desing as you do!!!

Hello, one more question, this time regarding the retracts. I bought those from hobby-china via the link in the build notes (JP Hobby Alloy Electric Retracts). Again, the dimensions seem to be off a little. Here is a photo of what I mean. I cannot fit it more in: https://snipboard.io/UlguS7.jpg
Also, in the main gear bay area, I cannot fit the retract cover as shown here: https://snipboard.io/ahCXG4.jpg, here: https://snipboard.io/CMnYOf.jpg and here: https://snipboard.io/hdbwCz.jpg The cover itself fits into the wing space but the retract seems to be too wide.
If I can ask, what are the supposed dimensions for the retracts? Also, may I ask what exactly is the nose/nose gear assembly supposed to be like (inside)?

Thanks again...

Here is a photo of the heatsink itself: https://snipboard.io/PXDWm7.jpg
And here: https://snipboard.io/ZhNtMn.jpg I attempt to fit it in, but I get this far, and then the friction/resistance is too high and I cannot push it more in with my hands. I suppose I could use some tools to get more force but I don't want to damage the motor, heatsink, or the housing.
I purchased specifically this heatsink: "Heat Sink 75mm for 50mm Motor and Ejets Jetfan 120 EDF" from turbines-rc.com as recommended in the build notes.

Can you post a picture of the heatsink to the RCGroups thread, imgur or another image hosting site?

Thread: https://www.rcgroups.com/forums/showthread.php?3054055-3D-printed-120mm-EDF-3D-printed-1-6-5-scale-L-39

The inside diameter is 54,4 mm by design, which usually ends up around 54 mm after printing. The heatsink should be 54 mm. Dimensions from a store that sells them: https://fanjetsusa.com/product/e-jets-jetfan-50mm-heat-sink/?v=4096ee8eef7d

Hello, I have a question regarding the EDF-housing. The motor with the heatsink installed does not fit it. I mean it barely starts going inside, but when I get it halfway in, I cannot push it more. When I measure the outer diameter of the motor with the heatsink attached, it is 55mm. And if I measure the diameter of where the motor should go in the STL file, it roughly equals 54mm. When printed and measured IRL the diameter is the same.

Yes. The inner panels stay attached to the fuselage and the outer panels are removeable. The flaps stay attached to the outer panels. This is done so that the plane will stand on the wheels without the wings attached.

are the wings detachable?

They don't need to open 90°, but if you can't get them to open far enough either move the bracket on the door slightly closer to the hinge point or extend the arm with a piece of plastic or fiberglass.

Different servos have different range.

Does anyone have a suggestion for FPV hardware that could be used/you use with this plane?

Whatever works when printing TPU. TPU printing is very individual to the printers. I have used many different variations of settings. 10% infill, one perimeter and 0,2 mm layers works fine. Two perimeters also works and gives stiffer tire. You'll probably need 4 bottom and 9 top layers for it to cap off the top and bottom with similar stiffness.

Hi, what settings should be used for printing the flexible parts (using TPU)? Mostly how much infill and shell thickness (perimeter count), bottom/top layer counts? Thanks...

Just a suggestion about the print times. I shortened the print times almost by half by printing with a 0,6mm nozzle at 0.37 height at a speed of 75. This creates a very strong print for the fuselage. Printing on a Anet A8 plus. I might go lighter on the wings, still testing.

I use Simplify 3D.

Have you tried printing? It might be fine in real life and only a preview artifact.Try turning off "Compensate Wall Overlaps" also un der the Shell. I don't use Cura but tried slicing now in Cura and it's fine.

Which slicing software would you suggest? I used Creality slicer for the most parts and it came well. I noticed the problem with the wings so I wanted to try Cura but it is the same.

I don't use Cura myself. Try the forum on RCGroups where. Something is wrong if there are holes with 0,4 mm extrusion. It's not a problem with the model. The material thickness there is 0,7 mm.

Each of the large parts of this plane can take two to three days to finish.

The problem still persists even with 0.2mm layer height. (print time over a day)
snipboard.io/Idunor.jpg

Why on earth would you use 0,4 mm layer height? Max 0,2 mm layer height.

If I use 0.4mm nozzle and print layer height 0.4mm and 1 wall line of 0.4mm, it is very similar: snipboard.io/N1FqxA.jpg
The print time is almost 17h with a print speed of 55mm/s (wall speed of 27.5mm/s and travel speed 150mm/s)

I use Print With Smile PLA now. It's very good. Just about any PLA will be good.

It's because you're extruding too wide. Don't extrude wider than 0,4 mm.

Do you guys know how to get rid of this problem (link below) when slicing? The surface is not seamless. I imported the STL file to Cura but it has these weird empty spaces. Here is the screenshot. I didn't notice this problem when printing nose/fuselage.

Which filament do you recommend?

2,5 mm or 3 mm self tapping is good. I use hex servo screws. Using just two screws is fine.

Hello, what screws should be used to screw fan intake to the fuselage-04? Also, I see there are three holes on the fan intake but only two on the fuselage-04? Should only two screws be used?

In simplify3D go to the Advanced tab in the print settings and select "Merge all outlines into a single model". This removes all internal structure and makes themempty solids. Use three or four perimeters to achieve 2 mm wall thickness.

hello.. would it be possible to give a solid file 0r stl file of the of the outer skin (2mm thick) only as we would like to make a mold for this model as the internal structures would be useless for us in the mold making process?

Rods are solid and tubes are hollow. You can off course use 4 mm tubes for the short joiner pieces. Try to figure out what the rods and tubes are there for any you will understand why they are as they are. Tubes are large diameter and hollow to save weight, or slide into each other, so outer and inner dimensions have to coincide.

And the 4x16 mm carbon rod? What should be the inner diameter? Should it be hollow or solid? (5mmx660 and 5mmx344 rods also)

yes (For all your questions)

Hello, where and what kind of rods should I order? I am a little confused by the dimensions. Everywhere I search I find: [External diameter]x[Internal diameter]x[Length]. Does 4x16 mm for fuselage mean 4mm external diameter and 16mm is the length? What is the internal diameter? And 9x11x576mm? Is external and internal diameter swapped? The same with the 11x13x576 carbon tubes.
Thanks for any help.

Glue in some wood blocks and you're set.
