I have owned this chopper for 2 yrs. It fly's smooth and steady. Great for taking video's from the air. I changed the tail rotor blade. A tail blade from a 53" QS8006 works great. Forward speeds are greatly increases and it can handle up to 5 mph winds with ease. A easy and cheap modification that makes a huge difference in this birds performance. It can get away from you on high speed so take some time getting used to the speed difference. Also, there is no warning when the battery is getting low. It just shuts off and drops from the sky. Keep an eye on the time when flying at high altitudes.

Just got it, tail went on easy enough. Looks awesome, flight test soon as it warms up enough outside. Tested it indoors to insure blades spun well. Only question I have, in order to replace the battery on the helicopter, and switch it with the replacement one I am ordering, as well as changing the front cover, how do I remove the cockpit? Be great if it just flipped up and off. I've flipped it off a few times not being able to remove it, <pun intended> hence no access to the battery. Also been looking for support online.

i have flown many 4,5 and 6 channel helis and i thought it would be fun to get a 3 channel to have fun with. it was one of the best desicions i ever made. but the only problem was that the heli constantly went backwards... ealily solved by gluing or taping 3 aa batteries under the battery pack. if you are thinking about buying this definately buy it!!!
