Rebuilt. https://rotorbuilds.com/build/6852

After release of 7 inch arms, I was thinking 4inch body with 7inch arms will look very cool and creepy as an Alien should be.
And I got serious... concept of this build was silent, high efficiency cruiser. Yes Prius quad with hyper thrust and coolness.

4in1 esc to emphasize its long long long arms. Or legs. I had to extend motor wires.
412g without gopro and battery. under 400 without TPU protectors.

2010 2400kv motor have enough torque and good efficiency with 7inch props i think.
(there should be some motors with better efficiency but I couldnt get one designed for quadcopters. I think this is the sweet spot)
For best performance, I should have used 6 inch body, F80 motor with 50a esc and giant battery...

Flying this for new spot soft target scouting before actual rippage and I am very satisfied.
It is very quiet (but sounds like a beast over gopro mic) and gets 5minutes of mild acro cruising out of 4s 1300mah. (15.1v)
With gopro of course.

Capable of most things except snappy quick flips and rolls..
