There are 3 different ones I am interested in....
Blade mCP X V2 .. $260
Walkera Genius .. $170
Nine Eagles Solo Pro 180 .. $230
I recently bought the Genius CP, there are some niggly little issues which have cropped up for some folks, but no more than you get on any other micro.
As you already have the 2801 radio, it would be the logical choice.
Blade mcpx are, like all Blade helis, expensive for what you get. It comes with a crappy radio, something worth taking into account.
Solo Pro 180 is ok (from what I have read), but is larger than the other two and one hell of a lot cheaper from Hobby King than that quoted price.
As with most of the stuff at the lower price end, you pays your money and takes your chance.
Whichever one of them you decide on, I hope it's a success story.
