5zero7rc HD1

My first build using a frame designed specifically to hold the DJI FPV Air Unit. For this build I chose the Rotor Riot HD1 frame paired with some Rotor Riot Acro 2207 2450 motors and a HolyBro Kakute F7 stack. This made the build super simple to wire up and the only soldering that is required was for motor wires to the ESC and the battery lead.

Some special notes on my build. I stuck the air unit to the frame with some velcro and a zip tie. The zip tie can slide a little bit and cover the memory card slot so there is no way the card can eject. I don't know if it was necessary or not, but I did install the capaciter that came with the ESC and there is plenty of room for it behind the camera.

Nice build. I was wondering how the air unit would fit in the HD1 frame. I have a Kakute F7 HDV stack that I will be using on my Apex HD frame.

How do you like the HolyBro Kakute F7 HDV Flight Controller? I was thinking about buying a couple of them.

Is PRM filtering working as expected in 4.1 with it?

I have not tried that yet but I plan to do that this weekend.

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..
