The Proto-X SLT makes the world's smallest quadcopter even more incredible! A larger 2.4GHz radio with dual rates is just the start; now, pilots can execute flips and other mild-to-wild maneuvers with a single button-push. An Auto-Upright system keeps the Proto-X SLT stable in any flight condition. Toss the quad in the air, and Auto-Correcting Technology keeps it level. Even beginners can fly the Proto-X SLT with complete success! The colorful body is designed for easy LiPo battery installation and replacement. Colorful LEDs make it easy to see the Proto-X SLT in any light condition. Also, since it comes with the SLT protocol built-in, pilots can fly this cool quadcopter with popular radio systems like the Tactic TTX650. As always, the Proto-X SLT comes with a USB charger and four spare rotor blades. All you need to add are four "AAA" batteries.
