I spec-ed out this build with low cost being a big focus. But didn't want to skimp out on the long range VTX or receiver. (since ultimately not loosing my drone would justify spending a little more on these 2 parts).

This drone is going to be used for cinematography flying over rivers and marsh, so GPS rescue is a must. I have gotten flight times of 15 minuntes so far using ZOP Power 22.2V 8000MAH 30C 6S Lipo (Weight: 920g). More updates to come if this build gains any popularity.

Also if anyone has a more efficient motor they would suggest for this built I'd love to hear about it.

Just out of curiosity why are you using such a bigmotor? I just bought one of these frames to use the gear off of my old TBS discovery clone. With the discovery clone I could get 15 minutes on a 4s 5200mah multistar. I think the weight and amp draw of those motors are whats hurting your flight time. Unless youre trying to do some acro also and need the power. With my 1kg ish Discovery clone I was running 2212 980kv sunnysky motors. Im sure there are better motors then those now but I think going with a smaller motor would help.

I've just switched to the Racerstar AirB 2514 1498KV motors. I haven't done any testing yet with them.

Great build! Does it needs to be 6s? I think you would be better off with those motors [£33.32]4X Racerstar 2508 BR2508S Green Edition 1275KV 4-6S Brushless Motor For FPV Racing RC Drone RC Parts from Toys Hobbies and Robot on banggood.com
or those more expensive motors
[£16.33]Racerstar AirA 2508 1200KV 4-6S Brushless Motor for Long Range X-Class RC Drone FPV Racing MultiRotors RC Parts from Toys Hobbies and Robot on banggood.com
and 4s as you would save 200gr weight on motors and have similar thrust.
Do you get oscilations with those thin for that lenght 4mm arms?

I haven't noticed any oscillation issues with these arms. I have been looking at upgrading to these motors(linked below) and saving the 3508 for a bigger build.

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..
