I've had a lot of £20-£40 RC helicopters and this is the only one still flying. So its durable but don't expect any micro heli to last forever. Unlike most of its rivals it does not have a sprung loaded throttle. I like it because it makes it easier to hover, you can even let go of the controls while hovering. The downside is YOU need to remember to cut power if you are about to crash. In most helis if you let go they default to no power.
It's a true 4channel control so you can move it around with either stick. Right stick moves it like "Pac-Man" left,right,forward,backward. Left stick moves is like "Asteroids" turn left, turn right and power. Sorry to anyone who did not grow up in the 80's!
USB charger can save you a lot of cash in "AA" batteries if you remember to ues it instead of remote. Unlike other helis which use counter rotating main blades this one has a single main blade with a "always on" tail rotor. This makes it more like a real helicopter. It has a Gyro which means it does not need constant adjustments to keep it pointing in the same direction. Its like a sparrow-hawk once it is trimmed. In summary; Great little heli, Lots of fun to fly, My favourite as its the only one of many still in the air.
