Here's how to wire an ImpulseRC Wolf PDB to a Kiss 4-1 25A ESC and a Kiss V1 FC on a Reverb build. Works for Kiss V2 FC too.
Decided to try a Kiss 4-1 on this one and had the rest lying around so that's what it got. It's so simple, does everything I need and is so reliable it was an easy choice to make. With V1 FC's so cheap and for such a small difference that'll stay for now(V2 hooks up the same) and the Wolf PDB gives me all the functions and capabilities I need.
I tried to keep this short so just screenshot whatever you need, the necessary diagrams and labels are included where needed. Use at own risk but works great for me.
