Operation - FUTABA T4GRS-24G Manual

Idle-Up "IDLUP"
This is a function select switch dial function. The idle up switch must be set.
This function is used to improve engine starting performance by raising the idling speed
when starting the engine of a gasoline car (boat). It is also effective when you want to
eliminate any braking effect when the power is turned off during running, due to the
effect of your gear ratio setting and choice of motor when operating an electric car.
However, considering safety, and to prevent the motor from rotating instantly when the
power was turned on, the MC950CR, MC851C, MC602C, MC402CR, and other Futaba
MC (Motor Controllers) will not enter the operation mode if the neutral position is not
confirmed. When using the MC950CR, MC851C, MC602C, MC402CR, or other Futaba
MC, confirm that the MC is in the neutral position and the set is in the operation mode
before setting the idle up function switch to ON.

Operation

The throttle neutral position is offset to the forward side. There is no linkage locking,
etc. because there is no change near the maximum operation angle even when the neu-
tral position is offset by this function.
