I don't have fpv, so I must rely on the 'ol eyes. I'm trying to think of a good way to mark the two front arms of my 1.1.1 so I can tell which way is forward, on the underside. Any ideas? I was thinking maybe some bright orange vinyl wrap on those two arms. I've used this stuff before and it is awesome. Here is a laptop cover I wrapped because it used to be pink. Its called 3M Scotchprint. Its a vinyl wrap, popular with car enthusiasts. You can heat it up and literally wrap anything. I don't do want to do anything as permanent as painting.
