Building |
- The foam surface is covered with 50 gr. fiberglass and red
pigmented epoxy
- Control is by elevons coupled to ailerons. (one servo on each side
moving the elevator and aileron to the same direction (Tailerons)). This
was building in order to have better aerodynamic inside the plane, as no
wire passes inside.
- Also built a nozzle into the rear part of the duct with an outlet dia.
of 58 mm. 5.total weight is 1 kg.

Take-off |
Bungy is helping with this setup. Never tried direct hand launch. |
Flight behavior |
Clean, smooth and fast. |
Landing |
Fast Landing, also due to the Tailerons + heavy wing loading |
