Q
What is the purpose of the “mustache” fairings?
A
Improve aerodynamic efficiency by
- increasing stability
- reducing drag
3
Q
Where is the landing gear attached?
A
2 points on the front cross tube
1 point on the rear cross tube
4
Q
What is the purpose of the spring extensions?
A
Used for shock absorption during autorotation and running landings
- have nothing to do with preventing ground resonance
5
Q
How is ground resonance avoided?
A
3 fitting points with elastomeric bearings
- rear cross tube attached with a metallic ring and protected by an elastomeric part allows for motion of the cell
