Got a blade nana cpx from Santa, I have absolutely "o" experience with helis. Been trying to mastyer the hover and I almost had it yesterday, I actually got the feel for it, for about 3 seconds before it fliped over and crashed for about the 150th time. All I can say is this thing is very durable, I've been beating it up against the walls, table , ceiling, ect for three days, hope to get the hang of it soon before it breaks.
Oh yea about your problem, thats exactly how mine reacts, I thought too maybe something was wrong but I found that if I apply throttle and get it off the ground at the same time be on the left and right stick to gain control, hard to explain being that I havent been able to hover the thing yet but almost there, anyhow the sooner you get it off the ground and into the air the better, even if it's a crash, I think.
