Epitaxial LuBa_{2}Cu_{3}O_{7-δ} films were prepared by flash evaporation MOCVD on LaAlO_{3}, SrTiO_{3}, LaSrGaO_{4} and ZrO_{2}(Y_{2}O_{3}) single crystalline substrates. The highest T_{c} and j_{c} (77 K, 100 Oe) values were 89 K, 2.7×10^{6} A/cm^{2} (LaAlO_{3}) and 88 K, 1.5×10^{6} A/cm^{2} (SrTiO_{3}) respectively. The occurrence of secondary phases inclusions in LuBa_{2}Cu_{3}O_{7-δ} films correlates with the possibility of epitaxial relations with the film matrix or the substrate.
