Hunter,

With a good transmitter like the DX6i and a belt driven tail the B400 will be much better to fly. I had the same thing happen when I was flying my CPP. I could fly it, but didn't enjoy it unlike my T-Rex 450. On a belt driven helicopter the tail is never twitchy and with a decent gyro you can take your hand of the rudder and it will stay there all day. Then you will be able to fly in stronger wind conditions and not have it affect the flying characteristics. All in all the B400 is a 100 times better and you will not regret it.
