in case of stalled motor and also protects the control in case of a short
in the wiring. Once the current reaches the limit current (shown in the specs.
control will automatically shut down. The user must move the stick on the
transmitter to the center (off) position to restart the control. The current
limiting has a start-up delay period of 1/10 of a second. During the first
1/10 of a second after moving the stick from the off position the current
limiting will not activate. This allows for high current surges when the motor
Tiny Smartcontrol is equipped with a 10 amp automotive type mini-blade fuse. The fuse is intended to protect the unit from a polarity reversal on the battery power
wires and shorts caused by water immersion. Replacement fuses can be purchased from most automobile supply stores.

The Diagnostic Light Emitting Diode (LED)
The LED provides the user with a visual indication of the state of the
Smartcontrol. This is useful when adjusting the unit and also for
troubleshooting problems in your R/C system. It is capable of displaying
3 different colors.
SCT Mk2 features;
Fully proportional forward and reverse motor control.
Built-in current limiting protects your motor and the control in case
of shorts or stalled motor. Current limiting has a start-up delay
to allow high current surges during start-up. When current limiting
is activated, it automatically resets when throttle stick is returned
to neutral position.
Standard limit currents are (custom limits are available, contact us for a

1 amp accessory switch. The switch is activated
by setting the control stick and trim lever to full reverse. The
Smartcontrol will stop the motor and start to sequence through on-off
states. Setting the trim lever back to center resumes

The standard receiver connector is similar to the Hitec "D" style
connector (shown above on the left). These connectors will plug into just about
any type of receiver, but lack the key tab found on Futaba connectors. The genuine
Futaba connector is available as an option on the Smartcontrol for a slightly
