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).

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
