Дальнолетство

Типовой 5“ квадрокоптер с моторами 2400kv, пропеллером 50x43x3 и LiPo аккумулятором 2000mAh летает при штиле со скороcтью 70km/h около 7мин.
За это время он пролетает расстояние около 7km, с остатком емкости около 7-10%.</description>

            <description>R6B reflashing

I share my experience.

Flashing the receiver is like flashing typical stm32f* but I am faced with the fact that memory bank of the receiver is locked for write at factory.

Unlock sequence:
# openocd \
   -f interface/stlink-v2.cfg \
   -f target/stm32f0x.cfg \
   -c &quot;init&quot; \
   -c &quot;reset halt&quot; \
   -c &quot;stm32f0x unlock 0&quot; \
   -c &quot;reset halt&quot; \
   -c &quot;shutdown&quot;</description>
