Hi guys!
Need your opinion on my latest project. I have built 14 multicopters before this inn many sizes from 100 mm Quad to 1300 mm Octo, but this one was a bit tricky. The intention of this creature is to be a small, stiff and robust, with a lot of power. I haven't done any tuning yet, since the maiden flight have been canceled because of the bad weather in Norway. I tried to fly inside today, but vibrations escalated, so I had to put it on the ground again.
I was hoping one of you smart guys could give your opinion on the setup (pro's and cons). I suspect it may be to heavy to be 460mm...looking forward to do some tuning. Will try the autotune, but not inside;)
Not worried about the vibrations, since the landing gear is soft, with 1,3 kg battery. Vibrations will probably disappear when I fix the landing gear mount and tune the PID's a bit....or?

Total weight is almost 3 kg with gimbal and GoPro 3
This calculator seems to want larger props...guess I need motormounts that moves the motors further on the arms.
