I've never seen an ETS pad under the landing board, a bit common sense is required and the rules state the pad (not the bird) must be within the confines (means inside) the boundaries of the loft, the bob wires and trapping are red herrings, theres no requirement for anyone, anywhere, whether clock or ETS, to have bob wires or to trap birds.
Standard Sputniks arent permitted so in my humble opinion the ETS trap should be on the inside with the landing board(without pads) should be on the outside.
This has been debated at length a dozen times on all forums.
