It's a pretty big step going from the MSR  to any collective pitch. They are just hard. I purchased two modles. A Blade Nano CP and a Walkera Genius CPx. The Genius is a very stable flyer but I am having power problems. the Blade is a great machine. It's very twitchy. I suggest going for the Blade. Parts are cheeper and easy to get. Just don't try to over handle the stick. Learn on mode 2 on your Transmitter. But it comes all set up. I just started a mo. ago but I can hover and turn around. That might not seem like a whole lot but wait till you get you hands on it.

Good luck it's a blast when you get it down.
