This DFU bootloader resides in the ROM of the STM32 core and is not erasable, so this bootloader is un-brickable (yay!). In order to flash those boards one needs a… Read More »

I did some Thrust measurements for a 150/160 sized quadcopter frame. The tests were done using an Eachine 1306 3100KV motor in combination with a Blheli_S 20A ESC (Racerstar 20A Blheli_S). The setup was powered with a lab power supply at a constant voltage of 12V simulating a nearly full charged 3S LiPo battery. In… Read More »
