Attemt at making some sort of decent aerial photography quad as cheap as possible.
At some level it was a success, on some parts it was total failure.

It works decently, but as I guessed, the arms are waaay too flimsy. FPV feed from upped fixed camera is total jellotown. I will replace the arms with carbon fiber arms when materials arrive.

Instagram post with some video and more pictures.

Pros:

  • 20min+ fligght time
  • Gimbal + gopro makes very smooth video
  • GPS flight position hold works well
  • Dual cameras are good
  • Lost model beeper, just in case
  • Somewhat quiet
  • Cheap

Cons:

  • Wobbly
  • Jello video
  • Gimbal has glitch which makes is tilt in some direction when copter yaws
  • Alt hold drifts a little
  • Had to rise motors higher to make room for the battery
  • Very annoying to open and very little room to work on.

Frame required some light fine tuning with basic tools.

End goal for this was to build some sort of copter that works and then change out what is needed to make it work even better, and I think I achieved this goal.

To do is a comparison between this and actual Phantom 4.

Enjoy a lot of pictures. :)

This brings me back.. I remember spending months trying to get decent footage out of my F450 and various gimbal iterations. I eventually gave up and moved on to mini quads. Those were good times though and I still think about building a larger quad someday.

I'm in the middle of a design similar to this. Great tip about the arms, I didn't realise they were that bad.
Nice build all in all.

Cool build. I like the FPV cam on the gimbal, clever idea.

Want to learn how to build an FPV rig? This guide will walk you through your first FPV freestyle build. These parts were hand-picked to balance cost and maximize performance. The TBS Source One is a popular frame for it's low cost, high quality carbon fiber. It's easy to work with and provides more than enough space for your electronics. We've got a 32bit 4-in-1 ESC to bring you the smoothest flights..

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..
