Thats the dumbest thing I've seen for a quadcopter. Once you're 200 ft away you can't see any color. I dyed my props red and blue and when it's 20 feet away they color starts to disappear. And what the hell is the string for?
Use the FPV or compass for orientation.
I dyed my props thinking I would use them for orientation but since it's not good for that use I do it for looks. I try different color combinations.
I agree, once the aircraft is any normal distance away you can't see any colours. Looks like it was designed by the DJI Forum Welcoming & Approval Committee while they were on one of their drunken binges.
Like it says in the add
"Accelerates the learning process.
Allows you to make quicker decisions. Can help avoid collisions due to shorter response time.
Much easier to see than the LEDs."
