chAIR -Manned multirotor Episode 20 -First Flight! Axel Borg

First manned flight with this aircraft. 162kg TOW total flying time was 8 minutes, which turned out to be 57% of the battery capacity. This means that the craft has a theoretical flight time of 14 minutes 100%DoD. 11min 10s until you are down to 80%DoD. My assessment is that 10minutes is the real safe flight time capability with the 35kg LiPo that are currently mounted on the craft. Overall the test went really well. There was a little more vibration than I had anticipated, and Yaw directional stability in forward flight was inadequate. In this first flight the I-gain limits were set to zero. Next flight the Yaw I-limit will be set to a value above zero to obtain better directional stability.
Regarding wearing MC suite and full face helmet etc. etc. This project is about obtaining the precious feeling of freedom. 10 min at a time LOL...-I know, but still.....so wearing a fortress would be counterproductive. I have tried to build in safety in the structure itself, so that I can feel FREE. Goggles and ear protection or headphones is a must. All other clothing is OPTIONAL. Im flying in a un-populate area, so I just might try flying nude. I promise to NOT make a video documenting that flight... LOL!
