We obtain contraints on three Universal Extra Dimensional models utilizing
limits from the CMS Collaboration on W' production and decay into a
single-top-quark final state. We find a weak constraint on the Minimal
Universal Extra Dimensions model due to small Kaluza-Klein number violating
terms. In contrast, the W' search puts a strong limit on the size of the Dirac
mass term of the quarks in Split Universal Extra Dimension models. In
Non-minimal Universal Extra Dimension models the W' search constrains the
splitting between the boundary localized kinetic terms of the gauge bosons and
the quarks. Each of these bounds can be translated into constraints on the mass
splitting between the Kaluza-Klein excitations of the SU(2) charged quarks and
the Klauza-Klein excitations of the W boson.Comment: 7 pages, 5 figures; Updated Draft and Figure
