We study the low energy limit of Little Higgs models. The method consists ineliminating the heavy fields using their classical equations of motion in theinfinite mass limit. After the elimination of the heavy degrees of freedom wecan directly read off deviations from the precision electroweak data. We alsoexamine the effects on the low energy precision experiments.Comment: Misprint in eps3 for the custodial model corrected and additional discussion of the triplet higg
