Cause it's dangerous to fly at night, could not recognize the attitude may make it crash.
I choose the cool light led tape.
Power supply is 12v. Need a specialized adpter between 12v and the tape.
Then stick the two adpters to the buttom of the coper. No space for them above now.....
Looks mess....but it works.....
Oh yeah! Looks cool!
Flight next night!
