Eclipson Cobra - 3D printed jet - Build guide

[@dsherburn]

Printing this out right now. Love that it does not need a bunch of carbon rods :)

[@Dreamer66617]

hey sneak dissing model x. its the best tho

[@ripmax333]

And it Can Take Off from Tramac! 😲 God bless You Eclipson Team!! Bravo!.... I will buy it!

[@st3v3nk3]

Take off is not the critical part. Landing is :D

[@ripmax333]

@@st3v3nk3 it depends how well the model is designed, if it holds its attitude during glide very well it shouldn't be a problem.

[@3DPrintHangar_RC]

This will beone of my next models for sure! Great editing and great choice of music 👌

[@ste4lthles]

Just the model I -wanted- needed.

[@TheArtyTech]

I wish the rest of your models had those joiners, I would pay for that kind of upgrade

[@AerialRCFun]

I don't even use joiners anymore, not that difficult to line up without them.

[@murderdoggg]

Good thing I watched your video After I printed the whole fuselage without bottom layers. o\ Doff, Imagine how hard it was getting fus1 and fus2 to line up.

[@eclipsonairplanes]

It is important to read carefully all the instruction. It will save a lot of time.

[@murderdoggg]

1:47 M2 screw x? M2 x 10? M2 x 13? This info is also not in the in the Cobra Instructions and temps pdf.

[@eclipsonairplanes]

In the shopping list you can find all hardware required. M2X8 .www.eclipson-airplanes.com/cobra

[@murderdoggg]

Thank you @@eclipsonairplanes

[@tonewavemw]

Is the edf not glued or screwed in at all? I’m using the xfly 50mm edf and the tabs on the side don’t let it seat in properly. Shall I snip them off?

[@eclipsonairplanes]

Screwed. Not sure what might be your issue with the EDF. Be aware that we have a FB group to solve all kind of printing assembly issue. Just upload some pictures and a description of your problem: facebook.com/groups/146642260886244

[@eijmert]

cool build guide but its very unclear. i want to print this thing but cant figure it out when looking at this video. like what are the things at 7:10 even for? and the pin at 7:25?

[@eclipsonairplanes]

Servos and tail skid

[@julian4035]

How could you blame this video... you have to have SOME knowledge about rc planes otherwise just buy a rtf model

[@eijmert]

@julian4035 why? Litteraly states "plane for beginners" And im not gonna buy a stupid ready to fly lol How is that even remotely fun? The whole point is trying something new.

[@julian4035]

Bro cmon you gotta know what a tail skit is...

[@julian4035]

The things at 7:10 are Servos... if you dont know what servos are your wrong in the rc plane hobby

[@CDXLIV444]

This one seems promising

[@Jaxa_fpv]

Super 🙌👏👍👍

[@thetallboyriley]

So fellow nerds, if we had a 3D printer that’s on that track (like the CR-30) which enables unlimited length printing, could we print the main body in one piece?

[@thomashowarth4818]

with midification yeah as you feed the wire through before you glue body together

[@jeffcossaboon5012]

I am curious as to how you did 1. The airframe design, 2. The graphic design, 3. Applied the graphics to the plane, 4. How you think it handles?

[@fab5111]

I just buy it but I don’t know if Hinge are in TPU or PETG?? Thx

[@eclipsonairplanes]

Hello. TPU or any other flexible material

[@adamtrzaskowski3901]

Can you replace the motor or esc after its glued together? It looks like it might be hard/impossible since the connection is not reachable

[@eclipsonairplanes]

Yes, it is posible,

[@geoffsim9736]

I didn't want to install my EDF until the end, so confirmed this was possible before I glued F3/F4 together 🙂

[@eclipsonairplanes]

Yes is posible to install it at the end.@@geoffsim9736

[@t2pt554]

Yes. Just unscrew the motor hatch and pull the fan out

[@spdrcr1010]

My printer isn't compatible with the flexible TPU filament, so I designed a small hinge that I printed in PETG with 1mm wire for a metal hinge pin. I printed the standard hinge tiles in the LWPLA for the fuselage joiners, and this seems to be solid. Let me know if you'd like me to share my hinge file.

[@eclipsonairplanes]

All printers are compatible with TPU, Direct drive is not mandatory. Yes you are free fo share the files if you want.

[@AerialRCFun]

I simply used a length of TPU (approximately 15 mm). Smashed ends a bit flatter where they are bonded to structure and used it like that. No need to print anything. TPU is very tough, difficult to tear so a hinge made from TPU will work fine even if it is only a very narrow strip. This was not on an eclipson plane, but it would probably work too.

[@marclecomte1614]

En construction en ce moment pour le Cobra

[@MyNameIsTibbles]

Interesting hinge design, is that TPU or just thin PLA 'plates'?

[@3pa908]

TPU

[@stadt-bremerhaven]

Is 95a tpu flexible enough?

[@pilotmiami1]

Bravo.perfect

[@carlosplover]

Where can u print the black connector pieces? I have the plane printing now and don’t see a gcode for them?

[@eclipsonairplanes]

They are called "hinge"

[@davidcerven5072]

1030mm wingspan is a bit small for what I'd like. Has someone printed this jet upscaled ? To around 1,5x or 2x the original size. If yes, how does it fly ?

[@eclipsonairplanes]

Yes! If you join the FB Group "Eclipson Airplane Pilots" you can find examples of scaled Cobra builds! facebook.com/groups/146642260886244/

[@jriley-tv1on]

Be careful when putting in wing joiner with CA glue... it could 'stick' or adhere before it goes in all the way.

[@julian4035]

probably better to do with epoxy

[@AerialRCFun]

I have used E6000 glue for this and it's nice, doesn't take much at all and easy to work with.

[@divisionbelarus]

If I print everything in pla, the edf of 50 with 3s would fly too and does it have to carry 4s?

[@eclipsonairplanes]

You will need 4S

[@davidterraza889]

I can fly with 50mm 4s 4500kv edf and a 1300mah 3s battery. It works like a charm, for sure the max speed is not so impresive but you can fly and learn how to fly an edf jet.

[@Bazf3k]

Is a 3S configuration possible?

[@eclipsonairplanes]

Yes if printed with LW-PLA

[@Bazf3k]

@@eclipsonairplanes Ok 😊

[@geoffsim9736]

I am planning to use my Dr.Mad Thrust 50mm EDF on 3S.

[@ОлексійСавченко-л7е]

Nice!!!

[@Nosydragon]

what infill should I use?

[@eclipsonairplanes]

All settings are outlined on the blueprints

[@Nosydragon]

@@eclipsonairplanes yeah but I use Creality print and not cura or Bambu lab

[@AnaLivia0702]

Muito lindo

Bro could make a killing on OF with those hands.

[@kjkareemslim]

what size is the ducked fan

[@eclipsonairplanes]

50mm

[@Cyberdyne_research]

im going to experiment with a 180% scale for a 90mm EDF with 6kg of thrust. 3:1 power to weight ratio!!

[@sharkmon69]

140% fits a 80mm edf, it moves pretty well.

[@davidwatkin1484]

How is the 180% working across all of the parts list? Do they fit on a 220mm square hotbed? Did you need to change any other settings? Thinking of doing a 90mm😎

[@vrosi1963]

retracts and flaps V2 i would buy one then

[@No-rh6zp]

Add flaparons or just add reverse thrust

[@jiritregler2333]

Super !!!

[@TDPro1]

Edf size?

[@EngineeringAero]

50mm

[@pilotimodele4598]

...😜👌

[@elxd43yt]

1:idh 3d printer 2:i dont have servos por motors and 3:i dont have money xd ñ

[@sharkmon69]

Print at 121% , fits a 64mm edf. I have 5 cobras. Or try 140% , fits a 80mm.

[@NicJamesDesign]

I'm assuming you've tried these scales? Great info, thanks!

[@KyleMeyer-z9l]

What about the servos? Just put bigger ones in because it’s scaled up?
