Adjustability:
•
More sensitive around neutral. (positive exponential, see example)
•
Less sensitive around neutral. (negative exponential, see example)
For ACRO throttle, exponential is applied at the low end to help nitro and gasoline engines have a linear throttle response,
so that each 1/4 stick increases engine RPM 25% of the available range. (In most engines this ranges from 5-60%.)
