Well, I borrowed my mate Phoenix disc and dongle for a couple of weeks. I have to say that it is very good, but, I have had a 4#3b for a weeka and a half now and WOW, I have to say I love this little heli. I have mastered nose in, forward flight (towards, away and side on to me), side on hovering and slow controlled circuits, all in a week and a half.
I'm not saying that buying and using a sim is not a very good idea, but if like me you didn't have the balls to progress at a decent pace with a larger heli then this is the training aid for you.
Now all I am waiting for is a weekend of no wind and rain to take my belt out and see what happens.
