Nice little ring.
I star down because it's a little too fade.
But very nice product well finished.
These are nice color and easy to fit on my quad too.Overall great quality as usual and while some are claiming they are unusable with regular radio receivers keep in mind that only the on off switch is at 760 US PWM and that simply plugging them into the receiver they will come on and work. I run a multi-Wii board and I have plenty of 5 V connections I can tap into to give them power. I may actually be able to dial the board down I don't think I be able to go that low though. Another option would be a receiver switch because they work extremely well I've used them on lights on all of my multirotor'sGreat Led Ring for a Hexacopter.
