(1.9m/75in). This is going to be a beast!

I'm curious about their new interlocking design. you can see some notches throughout the fuselage at the interfaces.

Raise the bar


Really nice work. The development time on this has been very long. I wonder if 3DLP has added so many new features on this one that they may have over cooked it. It looks like NACA ducts on the inside of the cowl? Looks like the wing folds lock down with a pin? Also the print quality of the prototype looks better than I have ever seen coming of a standard Prusa. This sets a new standard in design. Is that a Mig-17 he shows in the later photos? Cool Stuff.

Doesn't look like the fuselage interlocks. I think those are just glue joints. Could be wrong though.

As you increase in size complexity goes way up. There is a ton of stuff for them to draw, and testing it also takes much longer with so many big parts.

The fuselage joints are similar to those used on the pawnee wing. Makes sense, they are easy to implement and should give the necessary strength the the join but the´re not pretty. A solution would be to do it from the inside.

Are they just indentations to give more glue surface area, or does something protrude from one side to slot into the other?

The Dusty has those "slots" on the wings.

I am not sure IF I am to fill them with a CF plate cut to fit, OR NOT ?

I may have missed something with only a cursory reading of the pdf.

They occur at Part splits so maybe they are for reinforcements.

regardless I am NOT buying more 3d designs until ...
1. the joints are designed for much better mating.
2. there is some kind of concurrence on what materials to use
to avoid Heat warping of the model.

Simplify3d put out a Materials DB yesterday and ... well ... it's not looking good IMHO 8>{

Seems to me that there are female slots on both fuselage parts and then a flat dowel is inserted to join the parts. Its the same used on the pawnee wing.

I´ve looked better at the pictures on the second post, he is using those tabs on the wing too, its definitely the same as he used in the pawnee.

FLAT dowel ?

chuckle chuckle , no offense, it's gotta be a translation issue ;>} ;>}

Dowels are round.

That's why I thought those slots might be for a CF plate insertion.

Hey "They" haven't even put up a flight vid of the Duster yet.

OK it has been wintery north of the equator here too !

How do you call those "flat dowels"? Is it chuckle?

My english vocabulary is a bit limited. I bet you thought a "taco" was something to eat, in Portuguese we could call those little pieces joining the fuselage parts "tacos"

Maybe they´re learning with me

-Its probably because they are covered in snow in CZ right now.

In the USA Dowels are solid cylindrical Wood parts.

Chuckle is meant to be an insightful, yet respectful,
laugh at the crazy way our languages differ.

My comment about "north of the equator" was an acknowledgement about
OUR current weather conditions.

Although today it' has been well above freezing and all the snow is GONE ;>} Yeah !
But, with spring like weather the WINDS have returned ! :>{

WOW, Portuguese is has some serious variation from Spanish.

But don't change anything as I still enjoy a nice snifter of Port after dinner ;>}

If you said "dowel plate" it might be interpreted correctly.

Thats all right but how do you call those bits of plastic?

A taco can also be a stick like a hockey stick.
