Building the "K-Quad"

[CurryKitten]

Any idea what they are aitch, the rule of thumb is fairly light-weight, and pretty high kv.  In the 2000+kv for a 3s and 3000+ kv on 2s.  Looks like a sort of triangular mounting hole pattern there ?  The K arms have holes in a cross pattern, but it looks like you could pull the mount off and drill another hole or 2 if needed.
