Really good little chopper, co-axial, by Propel. Costco has two pack for $28.00, they are just about sold out! Comes with spare rotors, infra-red controller, LiPo charges in 40 minutes off Tx. 7-10 minute flight times. Could be charged using a LiPo charger but you would have to cut off the charge cord or come up with your own. Tx uses 6 AA alkalines, rechargables are an option you supply.
Has neat tri-color 4 stage strobe on the nose that cycles through the 4 modes of flashing, neat effects. Very rugged, has survived many crashes. Easy to fly, it's the best micro-heli I have flown and eliminates the pesky tail rotor for yaw relying solely on the two co-axial rotors for all functions( climb/rpm and yaw). Controller uses micro steps in place of pots on the sticks for economy, but it smoother than most, way better that Air Hog type controllers.

Best flight control is achieved in a hover mode, it comes trimmed for forward flight. A little weight on the tail will slow it down, but I found mine to be about right. It does not respond to yaw at all when at full throttle, so back off for steering. It turns right better than left, and has a trim buttons to increment the yaw trim under the yaw stick. These need to be adjusted as the battery runs down, but it becomes second nature after a few flights. Does not work well outdoor in sunlight as it interferes with the infra-red. ALL-IN-ALL, ITS A GREAT DEAL AND FUN TO FLY, I really liked this one Best out of all the Micro-Helis I've flown.
