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.
