The purpose of these flights test are to :

Since the previous flight done on April 11, 2006, some improvements have done on the model.

The gap between the blades and the streamlined body have been greatly reduced to increase the efficiency of the propeller.

The Center Of Gravity (COG) have been moved upward, the Lipo battery have been put on the top and just below the hull.

The Lipo battery used is a PowerHouse (selected cells) 3S1P at 11.1V 950mA (rated for 25C)
Lipo pack weight : 96 g

At 5 meters above the ground, the hovering is very stable...
