First flight and first blood

Hi :) Finally, we achieve such a configuration that our frame could raise for a few centimeters above floor. We have check additional battery and bought another couples of propellers. It was caused by not enough thrust – it was too low. We could achieve only ~300 g max thrust. We were using 2Cell battery and 9x4.7 props (CW and CCW). So we decided to do some changes ;) we decided to try recommended by producer both battery and props: 3Cell battery and 10x4.7 propellers. They promised to obtain over 700 g of thrust. In best ways we achieve ~550g, which is not close to that promises, but also good enough :) From simple calculations followed that theoretically we should flight:

4*550g = 2200g > 1000 g

Our frame weights below 1000g, but the propellers weren’t achieve exactly 550g, so approximately it looks fine. We didn’t want to wait, so we mounted our frame immediately:

We did two tests. At first time we used cable-communication, at second – wireless communication. The very good news is, that we have enough thrust to flight :) on above ~40% of full power quad  started to increase its altitude. But second start was not so fortunately and I have to visit surgeon:

We have to be more careful in next tests ;) Stay tuned with us!
