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..

What a sick idea! Definitely my next build :)

Great build! It just looks wickedly cool. Makes me wonder what a setup like that could do with some more powerful motors.

You should try! totally worth it. I am also curious what this can do with F80..

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
