Thoughts on EMAX motors? Looking at this set http://www.amazon.com/gp/product/B00Y2DJN4A/ref=s9_simh_hd_bw_p21_d0_i2?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-4&pf_rd_r=06JZYJ2TQ8555C014RR7&pf_rd_t=101&pf_rd_p=39da4d88-949a-537b-8229-23007adc147d&pf_rd_i=2234129011

And any major difference between the Naze you linked and the Usmile version?
