I started with a cp pro, no sim.

After 8 batteries I was hovering well and when I use the sim in the LHS, it is harder to me that the real deal.

Going to symm. blades will get you the ability to really fly and heli.....

Just my experience.

RADD'S flight training is incredibly good! I used it the whole way through! www.dream-models.com/eco/flying-index.html
