Switchback Pro with HDZero installed. Main things I want to point out:

• Same as my Switchback Zero build (some of the pics with red standoffs are that build) https://rotorbuilds.com/build/29978
• Buy the protective top plate for Switchback Pro HDZero Protection from HDZero (Very important) https://flyfive33.com/product/switchback-pro-wide-top-plate-hdzero-protection/
  • Cut your own top plate here: https://www.thingiverse.com/thing:5139939
• Space components out evenly on stack by using HDZero m3 nylon washers inbetween componets (do a better job than the gold standoff pictures here, follow the red standoff pics)
• Use low profile nuts on bottom of stack to save height
• Mount HDZero Race v2 vtx with update port facing forward so that the board is best protected
• Hold down antenna with included brass hold down - use solder on back side to keep nuts in place
• Use Welders Glue or e6000 glue to hold mipi connector down at camera and vtx
• Print my protective camera mount https://www.thingiverse.com/thing:5452428
• I recommend using a simple (but quality) dipole antenna since it is cheap and durable
