Meet Ciprian Raileanu and his personally built drift kart, Husqzilla. More info during the video.
For those passionate about aerial filming here is some info you might want to know:
We used a modified Carboncore Cortex frame with DJI A2 FC and a DJI Zenmuse gimbal for Panasonic GH4. We hate the A2 as much as we love the Zenmuse. Although we had terrible wind when we shot the aerials none of the footage needed any post stabilization. The A2 though is a total mess and we had big issues trying to maintain a constant altitude. Stay away from A2 if you are using coaxial multirotors. The only reason we are using it is because Zenmuse requires a DJI FC. If it weren't for this we would have went back to using ZeroUAV FC which is flying infinitely better.
