It would be great if there was a height option (low/medium/high) option for circle mode on the DJI Neo for the next update

Currently your option is manual take off and then engage circle at any height you like.

If you use the RC-N3 controller in conjunction with the Neo you can do exactly that already. Or if you control it with DJI Fly from your smartphone.

Hi there, thank you for reaching out. May I confirm the remote controller you're using with your DJI Neo? If you're using DJI RC-N3, you will be able to choose the height as per reply in #3.

Looking forward to your response. Thank you!.

You don’t need the controller. It can be done using the phone only.
