As shown earlier in a photo rendered picture i made a 3D CAD model of the rotorhead of my Logo700 xxtreme. I used this model to create the following animation which shows how a rotorhead works and how you can steer the helicopter in different directions.
The model is made in Autodesk Inventor 2014, and rendered in Inventor studio.
Editing was done in Apple iMovie. Let me know what you think:-)
