Very Nice Quadcopter looks like a coax heli. It is quite stable outside. It's very hard to fly it inside in a small room I think it should be better if It flies where there is a lot more room available. But it sure looks very cool with all spinning blades.
I really like your video, Thank its very informative especially for a newbie, The MQX Quadcopter lots of fun and pretty durable. I have always wanted to try a quad and I am thinking this is going to be a good intro into them.
