    Hello!

    I have a development drone (M500) that was purchased from Modal Ai. I was able to get it to connect fine. However, when I try to spin the motors using QGC, they spin only at low speed. Whenever I try to increase the speed, they fail and I lose connection. Can somebody help me figure out what the issue might be?

    Regards,
    Kiazoa

      @Kiazoa-Joao Are you using the wall power adapter or full batteries? The power adapter doesn't have enough current to support the motors at full speed.

          I just found out that my baud rate was off. I changed it to 2,000,000 and they're working fine now.

            @Kiazoa-Joao . Great!

            We have recently added a check to voxl-esc tools to prevent setting incorrect baud rates. However, the typo is still possible in PX4. I will add a check on the PX4 param in PX4 voxl esc driver.
