Plint

After a lot of practise flying my blade 120 sr and more practice on phoenix flight simulator. I thought i was ready to upgrade and bought myself the blade 400. Unfortunately i already had my second accident and are now desperate for help to get me to the next level without having to go through another crash episode. My flying with the 120sr is not bad and can do all of the normal staring to fly manoeuvres ie, figure of 8, nose in ect. I getting the feeinlg that I would feel more confident flying with another person or even spenind an hour on a 1 to 1 training might do the trick. I am based in the London Clapham area. Could someone please let me know where my nearest club would be or even better where I can get 1 to 1 help.?
Thanks...........
