  1. I used the v1.3 of iFlight SucceX Micro 16x16 stack.
    1. The gyro orientation needs to be adjusted after flashing latest Betaflight Firmware.
    2. There are two pads on FC need to be bridged for using IBUS.
  2. Honestly, top-battery-mount configuration was an after-thought, but it works.
  3. The motors were re-purposed from other builds, so the wires are too short to route inside the stack. If they can go between FC and ESC, then rise the stack a little bit, bottom-battery-mount configuration shall be achievable.
  4. Receiver sits in the back with a little bit dual-side sticky foam to keep it in position. Bind button is easily accessible.

Hardware Changes

  1. Switched the nuts came with FC stack for thinner ones and applied Loctite. The newer version of this stack seems come with thinner nuts.
  2. The rear aluminum stand-off was from VX110 frame kit. The stock ones should work just fine.
  3. Designed camera mount for Caddx EOS2. File Available at Thingiverse. 45 Degree is the maximum camera tilt I can get considering the camera size and the given height of standoffs.
  4. Use m2 25mm screw paird with nuts to replace both of the froont standoff. Applied Loctite.
  5. Designed antenna mount. Not happy with current solution, will design a new version later.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
