Adjustability:
•
More sensitive around neutral. (positive exponential, see example)
•
Less sensitive around neutral. (negative exponential, see example)
•
Adjustable for each direction. (ACRO/GLIDER)
For 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%.)
Special note for helicopters: Helicopter model types have just a single rate for each switch position rather than a rate for
each side of the servo’s travel per switch position. Additionally, setting the D/R,EXP for each switch position requires
cursoring back to the No. setting and changing the switch position here. Just flipping the switch does not affect the screen
setting, allowing dual rates to be assigned with idle-up and other features on certain switches, and does not require putting
the model in that condition to make modifications.
