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:

Since the original build I've converted my freestyle quads over to Crossfire, so I've updated the parts list below.

I also built a second version of this same quad, but using the Diatone Mamba F722 F50PRO 30x30 stack and Emax Eco 2306 (2400mAh) motors. It flies equally well, and with the bonus of Bluetooth connection to the FC (via the SpeedyBee mobile app).
