This beginner quadcopter has a lot of capability but it's hard to orient at all times. An LED array from a cheap flashlight and a 3.7v micro airplane battery makes a very bright headlight that doesn't weigh anything and really helps with figuring out where the nose is pointed. I was amazed how helpful this was when you really push the quadcopter to it's limits. The tiny battery powers the light for quite a while and could help in locating a lost copter!
