Check out this custom MWCD - 399 Super G Plus 7" HD Long Range/ Freestyle build. If you are trying to press the limits of your range and have GPS/RTH features this is a great setup. We average around 16-20 minutes using a 4300 6S LIION. If you slap a 2200-2500 6S LIPO you will average around 6 minutes flight time with gopro 9/10 setup.
