M1 dont turn by startup

[klopfie]

Hello everyone,

first of all sorry for my very bad english.

I just bought me the crazyflie 10-dof and i soldered the last 20 mins the motors on it. Then i turn it on and what is? M2-M4 turn and M1 doesnt turn. there is no voltage when i click the on button between the + and - point of M1.

Please help me to solve the problem .

thanks
Domenic
