The issue could be one of two things...

1) Heli is not completely balanced and trimmed

2) the ground effect from a small space.


I had the same problem when I first learned to fly my CP Pro a few months ago. The heli was almost impossible to control. My first issue is I assumed the Heli was RTF out of the box. This is not the case. I found out how to properly balance the heli after reading www.bladecprepair.com. Which made it much easier to control. However, it was still very difficult to control and very unstable. I was following Radd's school in the entry way to my house a (5' x 5' room).

After realizing it was the ground effect making the heli very difficult to control, I continued my over practice in a single car garage. It wasn't until I could hover a full pack and moved outside to practice forward flight that I realized there was still a lot of prop wash and ground effect making it difficult to hover.

I found it much easier to fly the heli outside and at higher altitude. Less ground effect and more room to recover.


just sharing some of my experiences...

here's a link to a vid of some of my past weekend flights.
