tricopter night flight

This is my DT 750 powered tricopter, with a set of Lumifly lights from hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=8830&Product_Name=Lumifly_Thin_Strip_LED_system
The video was taken at dusk, but it can be flown in complete darkness, as long as you know where the trees are! The lights are powered by a separate 900 mah 2 cell lipoly. Video taken by my lovely daughter Alyson, with a samsung L100 digital still/video camera.
