if you want a motor that will last longer get a brush less motor a lot more fly time because of efficiency and i takes a lot to burn them out. also you can get more thrust out of them i have a mega 16/7/10 with a 3:1 gws gear box. it produces about 32_34 oz of thrust also my dad sells batteries on there that would work with that type of motor look on ebay and search up real157 and look at the idems he has for sale

Good luck-
