A quick review of the Heliguy Viper mini quad-copter. It's great indoors or outside when it's very calm.
A very stable model that could be good for a new starter in the hobby if you can manage the orientation using the coloured rotors easily.
UPDATE (January 2013) - I've now been flying this for over two months now and it's still the first thing I grab when the weather is calm enough. Compared to other stable mini/micro machines like the Blade mSR this is a great machine for any capability. For a new person to the hobby it's an ideal first step to try out and learn the basics of hovering/moving with. It's very forgiving and still handles light wind when you want to progress to flying outside.
