Good stuff from Rick....
We really need some more input from you to help. Answers to Ricks questions will help.
Are you familiar with the "Geo Fence" and how that works ? If your in "Smart mode" and try to take of when your to close to the drone, it can appear to be erratic and can actually be dangerous if your not ready for it.
Advise you launch in "Angle" mode and switch to "Smart" mode after your in the air if that's the mode you want to fly in.
See this post I made just yesterday....
Range and limits
Is your firmware current for both the Box and Q ?
Did you calibrate "ALL" before your flight ? "All" being your compass and accelerometer ?
Do you have a sat lock showing in the box and do you see sats showing for the Q in the box ?
Hook up to the GUI and confirm everything is working before your next flight. Not needed every time but will help us evaluate the current issue....
Are you familiar with the hidden menu in the box ? If not...learn about it. Once you figure it out, calibrate your controls in the box.
Feed us some more details for better help.
