hum.. i think i have a potential problem with Google dji racing edition.
When I take the helmet off, the headband retract automatical
Is it normal ? Have you the same thing with your Google dji ?
There is both an adjustment wheel and a spring. Obviously the spring retracts. When extending with the wheel you can retract with a light push. All normal, you're wasting your time/money by sending back.
I set up my RE today and flown a couple batteries, upon removal the head band remains "open" as I adjusted it to fit confortably when on my head. It is anyway easy to retract "by itself" by a light push, so probably some units my be more smooth-flowing than others up to the point where they don't stay "open" and seem defective.
