WLToys V950 Explorer Series RC Electric 3D Flybarless helicopter is a 450 Size standard helicopter. If you have developed good 3D RC helicopter Skills and want to move on to bigger helicopters from Micro 3D helicopters, WLToys V950 will make a neat choice. It is cheap, its Ready to fly right outside the box and ready to do basic and advanced mild 3D Aerobatics. Equipped with Brushless motor, this helicopter has plenty of head speed for you to try various 3D aerobatics. Motor driving geared Tail rotor does a good job for a solid tail hold if you are not doing some crazy punches. 6 Axis Gyro System makes it very stable helicopter and does not allow any aerobatics even in idle up mode for beginners to learn to fly and or for you to just enjoy scaled flights in sports type of mode. All In all I will give it a good rating, despite of El cheapo quality radio it comes with. Rest does what its advertised to do.
