M1 FPV flying wing

M1 FPV flight model

The model was designed on the basis of another well-known model for FPV flights, but prepared for printing from LW-PLA

Several versions of the model with a wingspan of 1 to 1.4m was made and flown and the most optimal version span 1.2m was chosen

95% of the aircraft is printed from LW PLA with Heroid infill.

The model used about 500g of LW PLA and about 80g of regular PLA

The total weight of the model with a 4s4000 battery of 21700 cells is 1250g and the flight time is 25-40min, depending on how fast you fly

One of the features of the model is the modular design of the fuselage. The fuselage consists of 3 parts which are connected to each other by M3*8mm screws. In case of damage to any part of the fuselage, usually the front part, only the damaged part can be reprinted, without the need to reprint the entire fuselage. If a spare part is available, it can be replaced directly in the field with a single screwdriver.

This allows at the initial stage, when there is a high chance of damaging the model, to save a lot of printing time, a lot of plastic and more flying.

Wingtips are also removable and are mounted on 2 self-tapping screws 3*20mm

The center of gravity is located at a distance of 25-30 mm from the leading edge of the wing.

Preparation for printing takes place in the Prusa slicer.

In version 2.5, it is necessary to turn on the classic model slicing engine

Files in *.3mf format, in which, in addition to the graphics themselves, there are all the settings for printing LW PLA.

It is enough to change the size of your table for printing and just click cut.

The printing instructions indicate the approximate weight of each part.

Parts from PLA are listed separately and you can use your own settings if you want.
