GASB Two - The first fan jet fully printed


Ciao a tutti,
hallo everybody! Iím Carlo from Italy and for about one year I started to develop 3D printed planes.

Today I would like to show you my GASB Two printed for free by over 6000 people all around the world.

GASB Two was the first EDF plain printed in the world. It is a very good flier very very fast (over 150 Km/h with 3S and over 200Km/h with 4S battery).

Look on the tube GASB Two to see how it flights and see also the mod to add the mobile canards, then, download it for free from Thingiverse, print it and enjoy!!

Let me know your comments

Ciao
Carlo

Well done Carlo, it looks fantastic. What are its flying characteristics like?

How did you paint it or was the print material red?

Ciao,
Phil

As all model 3D printed are not paint but directly printed with material colored

Please see some videos of my GASB Two

Carletto,

I am currently printing a 1.35 size Gasb TWO V3
As I did not discover stl files at that size, probably missed them some place.

No matter as I'm just scaling in Simplify3d.
So far my EDF unit Fits ... just barely !
AND !!! This time I am attempting to follow your explicit Settings as you have so nicely
outlined those specs in your Manual ( pdf ). Ottimo lavoro

Did you have such a guide for the Gasb 1 ?

I will probably do the moveable Canard since I have even more room at 1.35 size.

Also, where do I find the Arduino Board Schematics, specifications and Program ?

I have been wondering about the Catapult too?
I have lots of Glider grade Bungee Rubber tubing already.
Any specs, angles ... "tricks" to offer before I cobble something of my own?

I AM going to try to use Foam wings and Foam Fins, to save weight.
I have them in CAD and will use the spar with Foam ribs and folded
at the Nose of a one piece TOP-Bottom Skin.

Time will tell.

Best

Hey Carlo,

Looks like a fun design. Judging from the videos you have posted on youtube it looks like it flies very smooth. Think I might download it from thingiverse and give it a try.

You mentioned there was an arduino on board in one of your videos. What are you using the arduino for?

Awesome work,
Rhys

I was wondering the same thing.

Maybe he will find time soon to address out question.
I Presume that it could possibly be for some kind of canard stabilization.

So my thoughts were why not use a fairly inexpensive Stabilizer RX
in lieu of any cobbled up arduino.

Then again it seems to fly just fine with fixed Canards.

I guess we will just have to wait for confirmation.

Ciao

Just a couple of pix to show my progress on the 135% monster Gasb2.
Check the Yard stick for length dimension.

Print times for each part at this size is quite loooong !

I have been hindered by messy "Finish layers at the tops that weren't smooth.

Still struggling with proper settings to achieve that smooth mateing finish.
I tried to do a dual properties print ( Slicer3d cabability) where I increased the infill % near the top.
It worked a little better, but ,I am thinking that I need to change the infill style
to a Grid vs Concentric to achieve a more uniform support for those top layers
and possibly add MORE of those top layers as well. Currently I am only doing 3 top and 3 bottom.

I also forgot to relocate the Start Point , another Slicer3d feature, on the Canopy which I intend to reprint.
You can see the restart point Blobs all over the top side of the canopy.
I have them on the bottom of the Fuse body as well even though I put the start point INSIDE the central fuse.

Regardless, I intend to make Foam wings Next.

It still "feels" a bit heavy and large for the choosen EDF .
It will definitely need the Slingshot launcher vs a hand toss.

More l8r

Bob
