Lets take this in sequence:<BR>
<BR>
The half roll on the diagonal leg of the Half Cuban TA maneuver, is performed in the middle of the diagonal.
And the middle of the Half Roll is the Knife Edge position, as you half roll the model.<BR>
<BR>
That middle where you place the knife edge flight, is in-line with the center of the 5/8ths loop that you will perform. In other words, draw a line betwen the loop's center and the Knife Edge, and make that line parallel to the ground.<BR>
<BR>
A couple of pointers: You will need to fly equal diagonal line segments before and after the half roll. Then start your looping element. Make sure you are flying a loop, with a nice round belly. Too many fellows rush this part and wind up making more of a square looking vertical dive. Many also rush after the half roll and don't fly the second diagonal element long enough.<BR>
<BR>
The maneuver sequence is: 1/8 loop entry to 45, Pause, Half roll in middle of diagonal, Pause, 5/8ths loop to exit. Entry and exit at same altitude and distance out. Radii of 1/8 and 5/8ths looping elements, same<BR>
