Edit: To my great disappointment and shame, this quad has been lost. Five seconds after takeoff over the Wakasa Bay of Japan, it fell to the watery depths of the ocean due to a faulty prop nut. The quad is gone along with a pristine GoPro Session 5. Oh well.

Use Case: Mid-to-Long Range Cinematic Cruiser with GPS and ability to spin 5-5.5" props efficiently

This build was inspired by some of my favorite LR pilots (Jet, Gab707, Docl8 an dothers) and the desire to produce some cool cinematic mountain surfing footage during my upcoming trip to Asia. Footage will be updated here after that trip. I'm experimenting with getting smooth, cinematic footage and long flight times on a 5" platform, rather than going up to 6 or 7" which introduces difficulties in getting smooth footage and the added weight of larger batteries. So far it flies wonderfully utilizing 1050, 1100 and 1250mah 6S Lipos. I want to try out some 1800mah 6S Lipos and possibly an 1800mah 4S Lipo to see if the power-to-weight ratio is acceptable for mid-to-long range mountain flights. I've got the Radix flashed with BF 4.1 and RPM Filters set up and it flies really nicely. The PID tune is about 90% of the way there, just working on reducing propwash and slight wobbles when cutting throttle after punchout. You can see in my build photos that I initially built the quad with loose wires, but I hate the messy look so I later rebuilt the quad with tidied-up wiring and plenty of cable sleeving. Not necessary, but I feel much better with a clean build. I went all out with premium components on this build and conformal coated everything for the first time. GPS is set up and working, just need to test RTH feature before really taking her out far. I did take it out past 1km without issue. While it is a bit heavy at around 700g AUW with GoPro and 1100mah 6S Lipo, it flies really nice and smooth which should work well for my purposes. The last photos featuring a Grey Fox were from a recent flight session wherein the fox came out of nearby bushes, investigated my quad and sat down beside me for a solid 20 minutes. It was surreal and very cool, also making for some cool photos.

Very nice build mate, what size cable sleeve are you using on the arms? is that 6mm or 8mm?

Looks like very clean build for the Super G 5.5.. Good to see flight footage and time for LR cine.. Was tuning OK and what are best PIDs so far.. Thanks

Sounds good.. Any sample flight clips coming and what approx flight times you get.. Thinking of similar build!

Just uploaded a flight from yesterday. I can get up to eight minutes moderately cruising with a 1250mah 6S pack and around 5 flying harder with a 1050mah 6S pack. Average flight time with how I like to fly is around 6 minutes.

Black Friday Sale at BetaFPV.com - Save 20% sitewide with coupon BFCM (Nov 27 - Dec 1) FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage..

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..
