FUTABA 7C-2.4GHZ Instruction Manual page 34

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%.)
GOAL of EXAMPLE:
Set up dual rates and exponential
in ACRO mode.
GOAL of EXAMPLE:
Set up dual rates and exponential in
HELI mode.
Note: In HELI mode the switch does
not change the rate being adjusted.
Change switch channel and switch
position with mode button.
STEPS:
Open D/R,EXP.
Choose channel and switch position.
Set rate (Ex: high rate = 95%)
Set expo (Ex: expo = -15%)
Go to 2 nd switch position and set rate
(Ex: low rate 70%)
Set 2 expo (Ex: expo = -3%) nd
Optional: if using a 3 position switch,
set 3 rd rate.
Close.
STEPS:
Open D/R,EXP.
Choose channel and switch position.
Set rate (Ex: high rate = 95%.)
Set expo (Ex: expo = -15%)
