[SOLVED] M4 not spinnig

[Qvims]

Thank you, I soldered the contacts using your alternative method, and it works great. Little bit hard to fly but it works!
Quick question, Is it normal for the crazyflie to trust forward as soon as it takes off?

Great that you managed to repair it.
It seldom keeps completely still in the air and this can be compensated for with the trim adjustments. However if e.g. on motor is spinning less due to a propeller being pressed against the motor this could happen, or if a motor is dented/broken. If you put the crazyflie on a flat soft surface like a carpet and maximize the throttle for a short while (trim set to 0) to "shoot" it up 1-2m in the air, it should go straight up if it is well balanced and all motors work well.

Thank you! I used you alternative method and m4 is spinning again, sorry again for late response.

I assume the same could be done for M3? Would I solder M3's white to M4's black and M3's black to M3's transistor?

Follow-up: It worked!
