sets the size of trim clicks. Exponential provides very fine steps close to the trim center, but larger ones the farther you get from center.  Default trim step is “Fine”.  (We like Exponential for a first flight on a new set up.  After we know how much trim the model needs to achieve hands off straight/level during the maiden, we’ll correct model issues that may be causing flight problems and/or switch to smaller trim steps for fine tuning in later flights.)  Check the Glossary for more details on size of trim steps.
