Finally finished and settled on parts after installing R9. This quad is built for just cruising around and maintaining a decent flight time.

Any updates on the total build weight and flight time?

DougS2K   15 days ago 

No update on the flight time yet. I was testing out my failsafe settings and ended up clipping a tree which led to a crash and damaged one of the ESC's. This happened just after waiting 3 months, yes 3 MONTHS, for a GPS mount. Currently waiting for a replacement from Banggood and it's taking it's sweet ol time to get here as well. Also took the liberty to order a spare ESC and spare motor this time in case of future incidents.

As for the weight. Without battery it's 490g, and totals 1016g with battery. She's a heft girl but still has plenty of power. Hovers around 28% throttle.

Can you get a DJI air unit in the Crocodile frame? It looks low but spacious.

Honestly not sure. There is quite a bit of room. Could take measurements if needed.

Haven't flown it yet due to winter weather but I'm expecting in the 15-20 minute range.

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..
