Graviton: my first 2x2 F3A pattern plane

Engine: OS160FX, pressure regulator CLINE.

RC: Hitec Servos (HS5625MG and HS645MG), dual power supply (PowerBox Sensor) with two 800 mAh LiPo, receiver SMC16.

Some accessories:

In order to learn to perform the aerobatic maneuvers more precisely, I decided to start the construction of a 2X2 pattern plane. It was during the year 2009. Meanwhile, I participated to F3A contest in the Sportsman category with my Galaxy. I enjoyed and I learned a lot. So, finally, the 2X2 pattern plane becomes my plane for the season 2010 in the National category.


Initially, I chose to build a plane inspired by the Insight V2 (http://www.insightrc.com) by changing the shape of the fuselage and some dimensions. Finally, the plane is completely different from the Insight, except the technique of construction of the fuse.
