新华网12月3日电 据科技博客Gizmodo文章，一种新型遥控直升机玩具可以向地面投射红色LED灯光，像一个小型的空中信使。
这款遥控玩具售价40美元，单从外观看,它与其他遥控飞行玩具并没有显著差别，只是多了一个小小的转动叶片，上面覆盖有LED条纹。正是凭借这个带有LED条纹的转动叶片，它可以向地面持续投射红色光。而且，它还配置了功能相当强大的直升机软件编程，可以随意打出想要显示的信息。
文章打趣道，在和平时期，这款玩具可用于发出善意的提醒，比如：“小心点，我可能会不小心让这个直升机靠你太近。”

The most dangerous RC toy ever devised, armed with an extra spinning rotor that displays custom messages. Because a foam arrow to the eye doesn't hurt nearly as much as the revelation that "Jason smells like poop."
The $40 RC helicopter doesn't look that different from all of the other RC flying toys you can buy, with the exception of a small additional rotor blade covered in a strip of LEDs that lets it display glowing red persistence-of-vision messages to those watching it from below. It even comes with what appears to be a fairly robust piece of software for programming the heli to display whatever you want.
In peace time it's probably best to go with a more informational message like "Be careful, I'm probably going to accidentally crash this thing very close to you."
