The very first flights were done yesterday night. I used the default parameters from the BOLT S|2, and it seems to fly very nicely. There is a bit too much power, I prefer when my copters hover at about 50% throttle (like the BOLTs). This one hovers at 33% throttle. However, the GEMïNï is built for speed, and too much power will certainly not harm. It will also be possible to carry the GoPro HD Hero I think. The GEMïNï looks amazing in hovering flight...: Due to the tilted rotors, the tail hangs a bit lower than the rest (see my 3D animation), which gives it a crazy look :-D .
Here are some images I shot this morning:
