Mockup

Underworld Dog

Sick Betaflight Cerberus. Amazing handling and power. I swear the motors on this thing were juiced somehow. 10/10 on the toughness scale.

Cerberus was Greek Mythology's 3 Headed Guardian Dog of the Underworld. Hades wasn't so bad if he was a dog lover like me.

I tried building a Raceflight Cerberus.

Unfortunately Raceflight experienced a major problem and my hand got burned by an unexpected full throttle spin-up while doing Motor Calibration. The motor threads caught the back of my hand and removed about 6 layers of skin down to my ligament. Raceflight owner and coder Preston Garrison could not explain what happened. I will NOT be using Raceflight now or ever again.

Many thanks to DiegoFPV for inspiring this build with a generous free Raceflight Revolt flight controller. I was excited to try a new software. I'm sad that it went so wrong.

Since I was not familiar with Raceflight I kept this build very simple with parts that I know will work well in Betaflight. All Red Everything Theme.

I have replaced the Revolt with a Mantis F3 (SPRacingF3 clone) that I got in a pile of junk that had been returned to a vendor. Betaflight 3.2.3 is flashed and the quad is working flawlessly.

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.
