Lukisegler-NG XS 3d-printed mini RC-glider

 Lukisegler-NG XS

• Span: approx. 900 mm
• Body length: approx. 500 mm
• Take-off weight (LW-PLA): approx. 100 g
• Controls: elevator / aileron
• Center of gravity: 7 mm behind the profile nose (next to the fuselage)
• Rudder deflections: aileron 15-25°  /  elevator: approx. 10°
• Weight: < 100 g

The challenge with this model was to build the smallest possible glider that can be created with a standard 3D printer and controlled with a conventional RC system.
It is printed in LW-PLA.
Additional parts are carbon rods, steel wire, some little screws and the RC system consisting of two 4,5 grams servos, receiver and the lipo battery.
The ready to fly model weighs less than 100 grams.

If you decide to build the model, I would appreciate a short report on your experience in the comments or you can contact me via the prusaprinter messenger.
This would help me a lot to improve the design my new models or to fix errors in the actual models.

The Lulisegler-NG XS should be printed from lightweight PLA (LW-PLA). The construction of the parts is designed for a minimum of retracts is necessary when printing. This minimizes stringing when using LW-PLA. Some parts however must be printed in PLA or PETG.

Modifiers are used in the print files . These are essential for the stability and for the structure of the individual parts! The surfaces for connecting the individual parts are made by using modifiers .

I also added kind of a short assmbly instruction as a PDF-file.

Parts for the construction

Carbon / rods or fiberglass rods as well as various adhesives are required for the construction.

Adhesives

• Superglue, low or middle viscosity

Carbon / glassfiber rods

• Carbon / glassfiber rod 1 mm: 3 pieces (450 mm length)
• Carbon / glassfiber rod 1 mm: 1 piece (180 mm length)
• Carbon rod 1 mm: 1 piece (820 mm length)
• Carbon rod 1 mm: 1 piece (540 mm length)
• Carbon rod 1 mm: 1 piece (100 mm length)
•  
• Carbon rod 2 mm: 1 piece (100 mm length)
   

For the elevator push-rod:

• Carbon rod 1,5mm (500mm length)
  The carbon rod must be shortened to the correct length. This depends on the servo used.
   

Steel wire

• Steel wire 0,6 mm: 2 piece (approx 400 mm length)

Screws

• Wood screws 2x10 mm (d x h): 2 pieces
• Wood screws 1x6 mm (d x h): 2 pieces

Electronics

Servos

• Micro (4,6g) servos: 2 pieces
   

Receiver

• Minimum: 2 channels
