3D model description

UPDATE - 231129
- Added Fuse01 without motor version(fuse01_nomotor.stl)

UPDATE - 221103
- Fixed some parts that interfere with assembly.
- Change the file with the same name to the updated file and print.

UPDATE - 221025
- Regenerated fuse04.gcode
- The print orientation has been changed (fuse04/upside down).
- Added missing wheel parts files(STL and Gcodes)
- Edited Parameter.pdf for wheel parts

UPDATE - 221024
- Added missing STL files(Winglet_L01/L02)
- The winglets are symmetrical, so it doesn't matter if you use the mirror function in the slicer for the wingle_R01/R02 part.

UPDATE - 221022
- There was an opinion that the channel for inserting the 2MM carbon rod in the FUSE01~FUSE04 parts was small and difficult to work with. I corrected this.
- The G-CODEs of these updated parts are not changed and cannot be used for print. Please use it as a reference.

= Specification

Wingspan : 4,000mm
Length : 1,430mm
Weight : 2,500 ~ 2,600g(AUW Include battery, after painting)
Wing loading : 33.5g/dm2

This is a Polish-made 18m class sailplane DIANA-3 aircraft with a wingspan of 4m scaled.
It is based on precise scale and modified to have airfoil and wingspan suitable for R/C scale flight.

Despite being a large aircraft with a wingspan of 4m, its READY TO FLIGHT WEIGHT(AUW) is only 2,500 grams.
The wing with an aerodynamic twist is designed with a gently curved leading edge and a trailing edge with Fine winglet.
Also, it has extremely low wing loading of 33.5g/dm2, stable flight is possible not only in thermal soaring but also on slopes.

The carbon pipe spars that intersect inside the fuselage are designed in such way that they not only stiffen the wing, but also
make it easy to connect and disconnect. Actually, only 1 steel pin makes them to be fixed.

It is effective for quickly gaining altitude or slowing down when landing because it has a large area flaps.
Ailerons and Flaps can be combined into program mixing in your transmitter for more effective roll control.(called flapperon)

By combining a motor of about 700~1,000 Watts and a 13~14 inch folding propeller, you can easily gain altitude even in an
environment without slopes or thermals.

A canopy that can be opened and closed easily with a latch system and a large inner space of the fuselage are easy to work with.

Basically, this aircraft is a sailplane, So, it is not suitable for extreme aerobatics or high speed.
You can enjoy a relatively slow but comfortable and elegant flight.

Intuitively shaped parts have been tried to make assembly as easy as possible

The manual contains detailed drawings, part numbers, and assembly order and methods.

Individual part may require cutting, grinding, sanding, drilling.

It consist of a large number of parts and require careful and patient crafting skills.

If you have the confidence to take on a challenge, try it for great results.

Flight Video will be uploaded soon.

3D printing settings

More than 90% of parts are printed with LW-PLA. Parameters and G-codes for reference are included with the manual in the ZIP file.

Almost all parts are designed for continuous printing.

filament : LW-PLA / PLA
Slicer : CURA
bed size: 200*200*200
