Are you looking for a mini quad for fun, fun and more fun? The U27 is what you want! Capable of doing flips and even inverted flight! Simply press the flip button and over she goes. After inverting you can then fly around upside down, performing flips in any direction.
The U27 has an Intelligent Orientation Control (IOC) System which eliminates the need to adjust the position of aircraft before flying. There is also three modes including mode 1 the maximum-stability mode for beginners, Mode 2 a medium speed mode, or Mode 3 which is the high-speed 3D expert control for maximum acceleration and maneuvers for expert tricks, including 180° flips and rolls.
The U27 comes with and is controlled by a 2.4Ghz radio system which ensures interference free flying. The model is completely pre-assembled and is a tough and lightweight design. It comes with blade guards and LED navigation lights making this mini-quad a comprehensive model that belies its size. It also has 6 axis gyro stability (3 gyroscopes and 3 accelerometers) to ensure level flight is maintained.

Very fast little drone, good battery life, range and a load of fun with the tricks. However i found the drone very easy to over balance in all avenues of flight, and it wouldn't always connect properly on setup and takes a few resets to get working. The guards are a necessity and over all i give this drone 3/5.UDI-RC Free Loop U27 Mini-Quad it rell inverte flight so fun funShort: Built well, very sluggish flight characteristics at all rates.
So, Build quality on this quad is the best I have seen on an RTF quad under $40. However, throttle response is awful. Mind you, It flies better upside down, but is then far less stable. Climb rate is slow and scary for acrobatics and even high speed passes.
This results in dozens of smashes into the ground and low obstacles, but thanks to the build quality it can handle it! Plus the quad knows when it is upside down, so no getting stuck. However this tank like nature is just a solution to the poor flight characteristics.
