Description:

Set contents are safe for beginners!
Easy specifications that can be bought and installed as is. Preset programs suitable for any car are built in. Also, connection to the motor can be done easily with a connector, so you don't have to worry. After the initial settings are made according to the manual, the car is ready to run.

Low-voltage cutoff function!
Lithium polymer and lithium ferrite batteries can be damaged if over-discharged, but VFS-FR3 is equipped with a low-voltage cutoff function, so you can play without worrying about over-discharge. The VFS-FR3 allows the user to select the battery mode at the initial ESC setting.

Selectable modes: Lipo/LiFe/NiMH, NiCD

Addition of back timer setting function
The time until the back-up operation is activated can be set by the trigger operation of the radio. This has the effect of preventing accidental backing up during fine brake operations such as pumping brake. 3 levels can be selected at the time of ESC initial setting. The manager software can also be used to make more detailed settings.

Long-awaited HCS support

KOPROPO's original “HCS” is supported. The communication processing time between the receiver and ESC is compressed to 1/4 of that required for a direct operation.

The mode is automatically switched when connected to a receiver. Of course, it can also be used in normal mode, so there is no change from previous compatible models.

Powerful BEC circuit for reliable 2-servo operation!
Equipped with a 6V3A BEC circuit (receiver/servo power circuit). The BEC circuit of the VFS-FR3, which uses expensive high-capacity elements instead of the parallel connection of 1.5A elements found in overseas products, will not be damaged even when two high-current servos are used in a 4WS. The VFS-FR3's BEC circuit, which uses an expensive high-capacity element, will not be damaged if two high-current servos are used in a 4WS or similar application.

Suitable for experienced drivers!
The VFS-FR3 has an unlimited number of motor turns, so you can change the drive frequency to maximize the performance of the higher spec motor characteristics. The VFS-FR3 is available with the same powerful output as the FR2.

Features.

Normal evolution of the VFS-FR2, which has been well-received for its ease of use.
Equipped with forward, brake and reverse functions.
BEC output 6V3A.
Equipped with a VFS function that can be set at 64 different frequencies from 500 Hz to 5.3 kHz for each of the 32 positions on the forward side, allowing you to change the throttle feeling to your liking.
Recommended settings for any car are pre-installed at the time of shipment.
The recommended settings are available up to the following number of turns.
If you wish to use a higher output motor, please adjust the parameters.
 LiPo] 12T or more recommended.
 LiFe, NiMH] 23T or higher is recommended.
Back cancel is available when setting up a single ESC. Back timing can also be set.
Equipped with a heat protector.
Voltage cutoff (selectable mode: Lipo/LiFe/NiMH, NiCD)
Back timer can be set until the back-up operation is initiated.
Neutral brake function
Neutral brake function - Use “VFS-FR3 Manager” for setting software.
