Source One 20mm

This is my lowered TBS Source One. Original standoffs were replaced with 20mm standoffs for a condensed build. I have been flying an Xhover Stingy for the past year and wanted to try something new. Really wanted to check out the Source One, but without giving up the COG of my current Stingy builds. FC is a tight fit which made individual ESCs on the arms necessary as a 4-1 ESC will not fit. Still need to design and print some ESC covers.

The original Source One camera mount didn’t work with the shorter 20mm standoffs so I created a RunCam Micro cam mount that can be downloaded from Thingiverse. Additionally, the top plate will need to modified a bit to fit the camera, I have attached a picture of the where the top plate needs to be dremeled.

This build turned out to be a great flyer with a nice familiar feel to the COG. The Source Once frame is very sturdy and lowering it has made it even more resilient to crash damage. Overall, I'm happy with how it turned out. Thanks for looking! :)

Nice man. The mount has worked really well so far. Hope you are able to get it printed. :)

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..
