Привет, отличная работа. Такой полный отчёт, но не написал какой в итоге вес(. Я думаю на 2s трудно реализовать весь потенциал 21700, 30минут отличный результат. Удачи,

Привет! Спасибо. Вес 87 грамм самого дрона и 142 батарейка. Батарейки выжимаются целиком и полностью, так как полетник 1-2s и он может работать на 5 вольтах, до которых выжимаются батки, летал недалеко от себя с 80% компенсацией просадки батареи и в конце просто резко тяга упала, когда дрон почти долетел до меня.

With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
