I want to share some information about my Zagi project. This is a bit bigger than a normal zagi but the structure is almost same with 2 servos, lot's of packing tape used and building time is not too long. The wing span is 3,3 meters and flying weight is about 10 kilos (22 lbs). I needed to add 1 kg steel to the front but the wing loading is still very low. One windy day I am going to try this piece of foam with 3-5 kg of ballastics on board.

First and second flights from the ground:

Based on 2 flights experience wing is very stable and easy to fly. I am really looking forward to try some slope soaring and thermal flying with this bird.
Cheers,
Mikko
