"Carbon Bug" Build Log - All Carbon, 3D Printed DLG

[@Argosh]

Beautiful. Looks like I might get a replacement for my sadly now tail-less Elf.

[@geode_rc]

Good choice!

[@lebojay]

I’m determined to 3D print a DLG one day. We’re getting closer. Thanks for this! My current 3D printer can’t print this material, but my next one will be able to 😎 Greetings from Canada 🇨🇦

[@geode_rc]

👍 … BTY, You can do it with PLA+ …. Check out my BUG 3DP in my YT channel

[@taoyeblue]

Bravo from Bambu Lab as a 16-years RCGroup member.

[@geode_rc]

Thanks for watching!

[@AerialWaviator]

Such an inspirational design. Many intriguing techniques used here from the printed wing jig to the use of carbon. Thanks for creating and sharing. ♥👍

[@geode_rc]

Very welcome!🤗

[@OliversAviationvideo]

Ive just downloaded this and cant wait to print it.

[@geode_rc]

Very elegant design. My only question in the build was the spring loaded rudder and elevator. I understand why you did this was for weight and ease of string servo control, but, as your crash indicated, expecting the spring up force during momentum didn’t happen as I predicted. I advise a lightweight aluminum rod (I have used bike spokes) to provide reliable servo control to surfaces. Otherwise many thanks for releasing the STL files, I am tempted to build it! Keep it up!

[@rehepeks]

I use spring and string even on 1.5M DLG. Never had any issues.

[@lebojay]

No decent DLG uses push rods. Too much weight and drag. Springs and strings are the way to go.

[@filipporossifavilli68]

the only thing I can say is THANK YOU!!!Greetings from Florence Tuscany...

[@geode_rc]

Thank you too!

[@franciscoblazquez9127]

The model looks spectacular, I need one in my collection XD

[@geode_rc]

Thanks you

[@SuperRaymondh]

fantastic design work! Cannot way to try to print and build this.

[@geode_rc]

[@carolinaboy008]

Good evening, printed the right-hand wing jig this afternoon and it printed as one piece instead of separated as depicted in the design layout and this video (3:48 minutes). I am using Cua as my slicing software, is there something that I need do to allow for this? Thank you!

[@geode_rc]

Best to use Orca slicer, otherwise you would need to export as “generic” 3mf from Orca/Bambu Studio, then open in Cura as “project”. If there is still problems, please share a picture ( preferably on RCGroups). Easier to debug 😀

[@Sandokans]

Hello. What material used for covering wings, and where did you buy it? ❤

[@geode_rc]

@@Sandokans I use so-lite. Most of the llight weight covering film will do just fine.

[@timmytom]

That's brilliant. Thank you.

[@geode_rc]

Glad you liked it!

[@charlesirons1892]

Wow, very impressive!

[@geode_rc]

Thank you! Cheers!

[@HoNau77]

Great and thanks for sharing!

[@geode_rc]

Thanks for watching!

[@bolleboom1]

goedemorgen...wat een super mooi ontwerp ..het eerste ontwerp was al super ....maar deze gaat er ver voorbij....printer gaat vandaag draaien

[@geode_rc]

Thank you very much

Hallo! Ik sprekt een klein beitje Nederlands. In 2000-2003, Ik woon in Amserstam. Ik kom bij Canada. 🇨🇦 🇳🇱

[@franciscoblazquez9127]

When I try to open your 3mf files with Cura or prusa slicer it tells me that there are no objects in the file, can you help me?

[@geode_rc]

This release is designed for Bambula Studio / Orca slicer. Thanks for downloading

[@robson.pampulha]

I had this problem but I managed to solve it. Do the following: install the Bambu Studio software. After installing it, add your printer (since we know you don't use Bambu) and then you will be able to open all the files. Here's a good and valuable tip: open a Bambu Studio window and another window that contains your printer. After that, use Alt Tab to switch between these tabs and copy the information from all the Bambu Studio fields that contain the Bambu printer to the other tab that contains your printer. If necessary, make your adjustments. Save the printer and filament profiles. In my case, I had retraction problems that were only solved by using high speed and pulling back a few millimeters of the filament. For retraction to work, set the filament retraction settings and the retraction speed in the filament profile and in the printer profile, otherwise there will be a conflict and you won't have the retraction necessary to avoid strings. Happy flying!

[@adametannecle2722]

Do you think esun pla-cf would be a good option? Just extra care for covering and storage?

[@geode_rc]

I think you’re doing great 👍

[@xoltri]

Why are there two horizontal stabilizers? It seems one of them has an additional bracing on the front 1/3rd, not sure which to choose.

[@geode_rc]

It's a tradeoff between strength and weight. Depend on how strong you like to launch.

[@cnsapam]

Am thinking of printing this using PLA+ instead of PA-CF, as PLA+ is more economical and readily accessible to me. Earlier thought of building Bug 3DP, but as I primarily use OrcaSlicer with Ender V3 KE, I found this files more easy to work with. Am almost done mapping all the files for my printer in OrcaSlicer. Any advice will be highly appreciated. I don’t have access to 7mm OD tube. Instead I can get 6mm OD or 8mm OD tubes, both of which are with 1mm shell thickness. Which one is recommended?

[@geode_rc]

Great to hear you’re making good progress. PLA+ is ok , just be careful not to over shrink the covering film. Otherwise, the ribs might bend. Same for tail feathers. 6mm will be better….. 1mm wall likely will be heavier than Skyshark P90 tube.

[@cnsapam]

@@geode_rc thanks for the advice. Will make sure that I don’t over shrink the film. As I’ll be using PLA +, will try to keep the temp lower when applying the film.

[@cnsapam]

@@geode_rc I have started printing few parts and they came out quite well. Currently editing/remodelling the pod_rib_c1 to change the hole which is for 7mm tube to fit 6mm tube (as per the relative calculation am keeping the hole to have diameter of 6.4mm). I hope thats the correct hole size for 6mm tube. Thanks again for sharing this model. Any chance if 4-channel with aileron version for 1 or sub 1meter DLG coming soon?

[@geode_rc]

@@cnsapam great know that you’re good at modeling. I use 0.2mm per side to compensate for the 0.4mm wall thickness in CAD. If needed, remaining thickness compensation is taking care at slicer. As for 4-ch dlg, I’m thinking about that… still long way to go though. BTW, if possible, please join us on RCGroups. It’s easier to communicate technical details on the forums with pictures/ graphics.

[@patraymond3791]

where do you get the carbon fiber parts like the tube and flat pieces? Pat

[@sosq222]

hi, by 2x 5gram serwos, what waight should be the battery ? Thanks for creating and sharing😁👍👍👍

[@geode_rc]

1S 350 ~ 500 mAh battery will do just fine. Some nose weight might be needed depending on your setups

[@carolinaboy008]

How do you get rid of the wall-looking thingies that are intervened within the object?

[@geode_rc]

Not sure which one you referring to. Could you show a picture? Or time stamp on the video?

[@jo21e6]

Which wingprofile do you use?

[@geode_rc]

AG37

[@phgi3593]

awesome . plane so elegant

[@geode_rc]

Thanks a lot!

[@michaelsanderssa]

Hi, where do i get the CG for this DLG?

[@geode_rc]

Please refer to lightnin bug for cg. Link to plan can be found in the faq section

[@AdemirAlmeida1503]

Very good. Do you have any projects with ailerons?

[@geode_rc]

Yes… for slope soaring …. kzbin.info/aero/PL9Pbd3mrLY1V5lDbKXBP0k-YYS6rrTWCN&si=tiKJRDUT9BaTQU-k

[@cakedayy]

where do you get your covering film?

[@geode_rc]

I got mine 15 yrs ago from local hobby shop. If you can’t find light weight covering film, try thinnest doculam (~2mils). I use that on my tail feathers.

[@vidmasze]

nice 👏 that's gonna be something to not wastefully use Bambu's most expensive PPA-CF filament on! (almost 2x stronger than PAHT-CF in some measures)

[@geode_rc]

Think about that too👍

[@vidmasze]

@@geode_rc really cool, even with just PAHT-CF this is already almost understuctable (used TPU for nose), been crashing to the ground without RC countless times - at least as good if not better than foam! wait until I recreate it with PPA-CF!

[@carolinaboy008]

What is the designing software that you use?

[@carolinaboy008]

I know now. I figured it out.

[@geode_rc]

👍

[@ilyaapokin1814]

3mf files are broken: can not open in any program... no object or parsing error at line 21

[@geode_rc]

Try Orca or Bambu Studio.

[@shobhitprakash]

Where do I get the files for this... if you can help.

[@geode_rc]

Please see link in the video description for the files.

[@phgi3593]

can i skining the wing with copypapper?

[@geode_rc]

Not recommended. Likely too heavy.

[@Sandokans]

Hello. It is possibile to put some small motor?

[@geode_rc]

I have an eBug with VTail on my to do list. Stay tuned.

[@lebojay]

If you want to print a motorized glider, there are many out there to choose from. I’m glad this is a hand-launch model; we need more of those.

[@pintony057]

Can you upload the files in the format stl files please :)

[@geode_rc]

STL only will lost lots of information needed to print. Please open the 3mf file using Bambu Studio or Orca slicer. Export the STL from there to keep the info needed for "modifiers" & print profiles. It is recommended to use Bambu Studio or Orca slicer than porting the STL files.

[@pintony057]

Hi, I'm downloading the file But something doesn't work for me with the file It comes in an incorrect format can you help thanks

[@geode_rc]

This 3mf release is for Bambu Studio / Orca slicers. Please give it a try again. Thanks.

[@pintony057]

Thanks for the quick response

[@jo21e6]

Can you upload the STL please?​@@geode_rc

[@jeromedupont8994]

the bug appears a 6.30 lol Nice build TEDDYBEAR

[@jeromedupont8994]

You design faster than we build

[@jeromedupont8994]

seems you put more dihedral on this one

[@geode_rc]

@@jeromedupont8994 yes, changed from 6 degree to 10 degree :-)

[@ripmax333]

Do you think the normal LW-PLA can also be used (Not pre-formed) did you tried it?

[@geode_rc]

@@ripmax333 it’s possible but will be softer. Be cautious when shrinking the covering or use Japanese tissue.
