You can match any turn radius with roll, and the tighter they turn the better it is for the dora. The concept of a shaping a vertical roll to match a horizontal turn elludes 90% of the ma imo. Noah thats no problem mate. I am a big fan of finding out the reality of a situation you should film your sorties and review i found that what really happens and what i thought happened are rarely the same. This is the point i was trying to make sorry if it came across in the wrong way mate. <S>
