This is the rebuild of my first b344 after it spent many months in the ice. It's insanly fast and efficient thanks to it's light weight (140 grams) and low surface area (25mm body and 12mm wide tapered arms) It can cruise at 40mph using 9-11amps and 80mph using 55-60amps.
Fastest speed so far was 93 mph on 5s with a broken prop. I know it can go MUCH faster!
The therotical thrust to weight ratio is 13:1 on 5s with 8in props.

I consider this frame a failure becuase I never came up with a good anntenna mounting solution(I would avoid buyingthis frame for that reason)

You should buy some antenna tubing to mount it. Amazing build btw.

How is the HD footage? I imagine it's difficult to iron out vibrations with such large props.

The footage the footage I get with stiff props is suprisingly clean, but flexible props with a large blade area (even after balancing) produce nasty jello at certain rpms.

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..
