[Courtesy of Richard Fletcher, October 1998]

As a long time pattern pilot converted to IMAC, here are some of the techniques I use -

1 - Use opposite rudder in a crosswind. When flying across the box in a crosswind, opposit rudder will help you to maintain track. Be sure to release the rudder before entering the next manuver or else your heading will be off.

2 - Dip a wingtip into the wind. This technique will help maintain track during looping manuvers in a crosswind.

3 - Use the elevator on up and down lines. This will help maintain a vertical line relative to the ground during vertical manuvers.

4 - Start spins late while flying in a strong headwind. Allows the exit to be much closer to center.

5 - Use the rudder on up and down lines while flying in a crosswind. Crabbing up and down the lines helps prevent the plane from getting blown too far in or out. If the manuver has a half roll in the line, switch the rudder during the half roll.

6 - Point the nose in or out. When exiting from a end box manuver, establish the line either slightly in or out depending on the crosswind. If the wind is blowing out, point the nose slightly in. This establishes the correct flight path heading toward the center to prevent getting blown out.

7 - Use the optional crossbox manuvers to re-establish position. If you have a humpty bump with options at one end, be sure to fly in if the wind is blowing out and out if the wind is blowing in. Even if the plane is in the correct position when starting the manuver, you will wind up in the wrong place when you exit if you don't go into the wind because the wind will constantly blow the plane the wrong direction during the entire mauver.
