The first prototye of the Flettner Rotor project is constructed with a modified Aluminium Byke structure (Not yet here since needs to be soldiered)

Materials list:

• Engine Absima with speed control + Battery + Charger
  Forward, Brake and Reverse modus
• Engine Pulley *Riemenscheibe
  
• Industrial bearings *Flanschlager

This is the first sketch and 1:2 drawing

The first material used to build the cilinder, that at the end is not at all a cilinder but a romboid structure.

Many thanks so far to :
