Always turn on the transmitter first, then turn on the speed controller's 

power. 

After speed controller's power supply is turned off, then the power 

supply of the transmitter should be turned off.

The receiver will pick up noise when the order is reversed. 

 

 

This may cause the car to go out of control and may cause 

 

an unexpected accident.

Please do not connect the wire for

the motor until standard setup is

completed.

Connect it the negative side of 

the motor.

Connect it the positive side of 

the motor.

Generally, the number of turns of a motor and the load to the speed controller are not necessarily related. Although it is possible to use a motor as long as it is marketed  

  

 for electric cars. According to the usage condition, the thermal protector works regardless of the number of turns. Please decrease the load by changing the gearing, 

  

 timing, motor etc. when the thermal protector is engaged.

standard setup of the speed controller again.

The braking feature will operate on the VFS-FR when moving the throttle trigger from the forward position to the braking position in the standard setup. Reverse will only be engaged by returning to the neutral 

position after braking, then moving to the reverse position. When reversing and you are not in the neutral position, forward will not work. Moreover, please note that reverse might not start well when a neutral 

position is adjusted by the trim of the transmitter after it has been set.

Repeated brake operation or pumping of the brakes, the VFS-FR2 may begin the reverse function suddenly. In this case please use the reverse disabled mode.

The load to the motor and the speed controller might increase when changing to the linear reverse setting. The thermoheat protector may engage early. Please use it after it has cooled down.

The standard setting is is completed with the above steps. When 

not in use, please turn OFF the power switch of the VFS-FR2.

Various parameters can be set by ICS (Interactive Communication System) besides the drive frequency.

Frequency of brake: Initialization is about 5.0KHz. The brake frequency can be changed to 64 different frequencies ranging from 460Hz-5.3KHz.

Throttle mode setting: The operation of the brake and reverse can be selected from three modes.

The power save voltage: The power supply output supplied to the receiver can be set while maintaining a constant voltage. This allows for a 

 

steady to the last minute run.

Throttle response: The throttle operation of the beginning grasp can be changed to be mild. This combined with the punch function of the 

 

transmitter can have your car start like a rocket. This especially benefits if the surface conditions are slippery.

Current limiter: A large current to the motor can be suppressed. A set value OFF is also possible. This setting aids in extending runtime by not 

 

over using the current that you would need.

To change a frequency or another setting of VFS-FR2; with No. 61028 ICS USB adapter HS and OS after Windows XP or latest PC, other selling

   PC software VFS-FR manager V1.2 (download from KOPROPO HP) is necessary. (We cannot guarantee the using in Windows8.)
