I have a Stinger running SDK 1.5, and I am unable to takeoff. Connecting the drone to QGroundControl gives me a "Ready to Fly" status, and I am able to pair my remote with it successfully. 

On setting to Manual mode, arming, and throttling up, the status in QGroundControl transitions to "Armed" then "Flying". However, the props do not actually move. Trying to pitch, roll, or yaw does cause the appropriate pair of props to begin spinning, but no matter what value I set the throttle to, the drone doesn't actually spin all 4 props at once to take off. 

Here is a quick log demoing the behavior.

Any assistance would be appreciated.

Hello,

This behavior sounds like turtle mode may be engaged. What are you using for a controller? 

If it is a zorro blue the turtle mode switch is in the top left. As a general rule of thumb all switches should be away from you prior to arming. Controls have changed slightly since the guide on the docs page has been updated. I am working on updating them now. For now, please see the image on [this forum post](https://forum.modalai.com/topic/4964/stinger-fpv-blue-zorro-goggles) for current control mapping.

Hope this help,
Robbie

I forgot to post the resolution, oops.

It was indeed turtle mode. That channel was not mapped on my remote, and I ended up having to adjust the relevant PX4 parameters to disable turtle mode entirely.

Thank you for the assistance!
