FT Guardian Gremlin v2 motors shut down immediately on liftoff

[natek808]

Hi,

I have a freshly built FT Guardian Gremlin v2. When attempting to launch, the throttle appears to be working properly but as soon as the quad lifts off the ground, all the motors shut down. I then need to disarm and re-arm before the motors will run again.

I also tried holding the quad from the top( battery). Running full power to the motors works fine, no shutdown happens. If I 'drop' it when the motors are applying thrust the motors shut off immediately.

I've gone through the config videos, updated the firmware and reloaded the config file?

Any suggestions of what to look at next?

Thanks!

This ended up being a motor rotation problem!
