Jump to: Introduction Specifications

Tiny Smartcontrol Mk2 is a state-of-the-art electronic motor speed control intended for radio controlled models. The Mk2 is designed around a microcontroller, which give it some unique capabilities.
The Mk2 is equipped with both an input fuse and current limiting circuit to prevent damage to the control and your motor. Four different current limits are available, as described below. Standard on the Mk2 is the accessory switch. These controls are designed to operate for an unlimited time without overheating. The controls can be purchased with or without the plastic case.

The SCT Mk2 is compatible with the 2.4GHz Spektrum RC System. 

Current Limiting

Smartcontrol features automatic current limiting which protects your motor 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 above) the 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 is starting.

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.

The Fuse

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. Replacement fuses can be purchased from most automobile supply stores. 

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 price quote)  :
  • 6.6 amps
  • 4 amps
  • 2 amps
  • 1 amps
• 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 normal operation.
• Compatibility tested with:
  • 2 Channel - Futaba, Hitec, and Airtronics.
  • 4 Channel - Futaba.
  • 5/7 Channel - ACE Nautical Commander
  • 2.3 Ghz Spektrum System
