While we are on the subject . .

1/ OK, I know what exponential is, but what exactly does the percentage mean? Percentage of what?

2/ When putting exponential on the elevator, be careful of the effect when inverted. Most aircraft need a little down elevator to keep level while inverted, which 'uses up' the soft part of the exponential curve, placing you in the steep part of the curve. This means the elevator control is actually more sensitive inverted than it would be if no expo was dialed in.
