"How to build a 1/4 scale demoiselle model"

[Gabriel Voisin]

Hello together,

I'm from Germany and I want to show you how to build a 1/4 scale Demoiselle.

I will do it step by step and I hope you enjoy it.

greetings Gabriel

Alberto Santos Dumont's aircraft were slightly in construction.

Many of the supporting parts are made of bamboo and metal tubes.

The Demoiselle No. 20, technical data from the Musee de l'air documents.

Wingspan 6,35 m

Length 6.65 m

Height 2.20 m

Weight 120 kg

1 x Dutheil-Chalmers (Darracq) 35 hp

My 1:4 scale model:

Wingspan 1,58 m

Length 1.66 m

Part 1

The material:

Pine strips

Pine round bars

Brass

Brass tubes

Copper wire

Steel wire

Cable

Solder, and various small parts

Photos 1 show the drawings and lots of photos from the Musee de l'Air in France.





Part 2.


All clamps are drilled for the brass tubes. So we get a better grip and the alignment is much simpler.

First we build the fuselage.

Lay down two of the wood strips on the plan and transfer the position of the clamps.

The tubes we cut to the length and then solder with the clamps.

One of the pictures shows the universal joint of the tail and you see the front section with the motor mounts.

The main part constructed with five brass components.
