Built this as a backup freestyle quad.

I didn't need all the height that 30mm standoffs provide, so I wanted to run this with shorter (25mm) standoffs. The main challenge was finding a way to mount the camera, since the stock carbon camera plates won't fit with shorter standoffs.

These are the mounts I ended up using:

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

Now we've got the best of both worlds and what..
