Differential Aileron Travel
Differential aileron travel assists the model in turning more
aerodynamically efficiently. Aileron differential causes the
aileron to travel more up than down. This creates less drag on
the down traveling aileron, resulting in less adverse yaw. This
can be done several ways. The most popular methods are
mechanically or electronically. The AccuThrow can be used to
quickly and accurately check the amount of travel of each
aileron. This should be done with an adjust-and-fly method.
Make the adjustment, record the settings, fly the model and
readjust if necessary.

When you prepare to insert the wire into the base block, first examine the
90-degree bend in the wire. You can check this against anything square, such as
the corner of a sheet of paper. This angle must be 90-degrees or slightly less. If
the angle is greater than 90-degrees, the wire will tend to pop out of the slot. Use
a pliers to change the angle, if necessary.
