The GTFO kit is a complete GT overhaul VESC kit that will replace the controller, BMS, AND motor of your current GT build. This will take your mid GT build and put it on par with a high voltage VESC. This kit is the closest you can get to plug and play. And YES! This WILL work with your XRC!

(This install video is a bit outdated, it's still using the Thor300 and the LiTech BMS. But you can still use this as reference!)

We don't currently have a guide on the VMS installation of the GTFO kit. Please watch our temporary GTSFO VIDEO GUIDE to get a rough idea on how to plug in your GTFO VBMS. Proper guides coming soon!

The parts that come with the GTFO kit are;

• The Thor301 with a GT mounting plate

The Thor is mounted via M3 Allen screws, the plate is mounted via M2 Allen screws.

• The GTFO 12v RGB lighting kit

A 12v RGB status bar. LED count 10. Is an adapter for the power button and potential can-bus from the rear (can-bus currently unsupported).

A 12v RGB front status bar. LED count 14.

A 12v RGB rear bar. LED count 15.

The LEDs on Thor's work in a chain; STATUS - FRONT - REAR. In this case most of the inputs are routed through the status bar itself.

• The VBMS

The VBMS is our newest smart bms- a collaboration between Fungineers and VESC. It is mounted on a breakout board designed for stock 18s Future Motion GT's.

We currently do not have a video guide dedicated to the installation of the VBMS. This is a work in progress, however you can watch the GTSFO video guide linked above for an idea how it works.

Documentation and specs for the VBMS can be found here

(OUTDATED, REPLACED WITH VBMS)

• A Li-Tech supported Drop-in Smart BMS

This BMS is powered by Li-tech and only supports 18s, FM GT and XRC battery configurations. (The XT60 on their batteries are reversed, be mindful!)

Max charge amps - 5a

60a fuse - link for fuse, REOMAX R1245.60 SURFACE MOUNT FUSE

Connection Orders;

DISCONECTION - Balance leads first (white connectors), followed by XT60's (Yellow connectors).

CONNECTION - XT60's first, followed by Balance Leads. Never lead balance leads connected by themselves.

This BMS is not configurable.

• The Superflux HS / HT (optional, the Superflux will NOT work in an XRC frame as we don't currently have axle blocks for it)
• Superflux Mounting Blocks / Hardware kit for GT (optional)
• Superflux Female Connector (optional)
• A stock GT motor connector (optional)
• GTFO Tool Kit

Our kit also comes with a toolkit. It includes;

-A T9 Security Bit

-A 2mm S2 Hex Bit

-A T25 Security Bit

-A PH1 Phillips Bit

-A T20 Security Bit

-A Socket Wrench for these bits

-A Wrench for the Axle Bolts

GTFO T301 Pin Out (This is more of a wiring guide than a pin out, your kit should come with preassembled wires so it's a matter of plugging them in right.)

GTFO Programming guide-

Ok read this carefully, this is our GTSFO set up guide. In the video we use an GTSFO to set up, not a GTFO. Due to the multiple configurations of motors, we are not able to accommodate for every configuration yet. The kit will need to be programmed, the video below will walk you through step by step with either FloatHub or Vesc Tool. This video is designed with both the GTSFO and GTFO kits in mind. These two boards have slightly different values that are completely incompatible with one another. Please use the correct set up values for your device.

Set up values;

(These values are found in the initial Motor Wizard)

S-Count: 18

P-Count: 2

Capacity: 8.4ah, Full Voltage 75.6v, Empty Voltage 54v

Discharge Current Max: 80a

Charge Current Max: -45a

Motor Set Up Values (The CURRENT values used for a Superflux don't work for a Hypercore, vice versa)

(These are found under MOTOR CFG - GENERAL - CURRENT)

Superflux Current Values: 

Motor Current Max: 160a

Motor Current Max Break: -160a

Absolute Maximum Current: 240a

Hypercore Current Values:

Motor Current Max: 120a

Motor Current Max Break: -120a

Absolute Maximum Current: 180a

(These values are found in MOTOR CFG - VOLTAGE)

Low Voltage Motor Cut offs; 45v Start (2.5 x S-Count), 41.4v End (2.3 x S-Count)

(These values are found in REFLOAT - SPECS)

High and Low Voltage Pushbacks: HVT - 77.4v (4.3 x S-Count), LVT - 54v (3 x S-Count)

(This value is found in MOTOR CFG - FOC - FIELD WEAKENING)

FIELD WEAKENING:40a at 60%
