Thank you for your help.
Yes it is Flytrex, I think I had a blonde moment as Fl looked like an A.
Next question, is it worth keeping it attached as I see it is no longer supported.
Hi I just brought a Phantom 3 Pro, second hand.
Upon reciving it, I noticed it had been moded wit a small black box on the side.
It looks like it say's AYTREX.
Any ideas ?
