[. . . ] The GTB ESC is designed to operate comfortably from 160ºF-180ºF (warmer than typical brush-type ESC) with motor temperatures also around 160-180ºF. If you had a low turn modified brush-type motor in the vehicle before switching to the GTB system, and you do not change gearing, you will be over-geared and the vehicle will have slower acceleration! 1 no 0 yes 3 20% 20% 4 2 yes 100 yes 3 20% 20% 4 3 no 0 yes 2 20% 20% 4 4 no 0 yes 3 40% 40% 4 5 yes 25 no 3 20% n/a 5 6 no n/a yes 3 20% off 4 NOTE: GTB is factory set to Profile #1. profile selecting brushless profile s : all LEDs Start within these final drive ratio ranges in the vehicle: 8. 75­9. 25 : 1 Velociti 5. 5R in Touring Cars (rubber tire) 7. 75­8. 5 : 1 Velociti 6. 5R in Touring Cars (rubber tire) 11. 5­12. 0 : 1 Velociti 5. 5R in Off-Road Buggies 10. 5­11. 0 : 1 Velociti 6. 5R in Off-Road Buggies 13. 0 : 1 Velociti 5. 5R in Off-Road Stadium Trucks 12. 3 : 1 Velociti 6. 5R in Off-Road Stadium Trucks Higher final drive ratios will give longer run time at the expense of top speed. Lower ratios will result in higher ESC temperatures--too low may result in overheating & thermal shut-down. With ESC on & connected to a charged battery (transmitter ON or OFF): 1. [. . . ] QUICK PRESS (& release) SET BUTTON WHILE LEDs ON SOLID ESC changes modes, and the Green LED will flash for a few seconds (with Blue & Red LEDs still on solid) to let you know you have changed modes. Note: there is a time constraint during this selection process. 3. TURN ON THE SPEED CONTROL'S POWER While still pressing SET button, slide ESC's ON/OFF switch to ON position. 5. CONTINUE PRESSING UNTIL BLUE & RED LEDs COMES ON Note: you will continue holding past the Red LED One-Touch indicator. 6. RELEASE BUTTON AS SOON AS BLUE & RED LEDs COMES ON Blue & Red LEDs flash 9 times, then turn on solid after a few seconds. 7. QUICK PRESS (& release) SET BUTTON WHILE LEDs ON SOLID ESC changes modes, and the Green LED will flash for a few seconds. 8. ESC EXITS MODE SELECTION & RETURNS TO NEUTRAL Green LED will flash continuously at neutral (w/Red on solid) indicating that sensor harness for the brushless motor is disconnected from ESC. 8. CONNECT BRUSH-TYPE MOTOR TO ESC Refer to BRUSH-TYPE MOTOR portion of STEP 3 on main instructions (pg. 3) for wiring. 9. RE-CONNECT BRUSHLESS 6-WIRE SENSOR HARNESS TO ESC Refer to BRUSHLESS MOTOR portion of STEP 3 on main instructions (pg. 2) for wiring. IMPORTANT PRECAUTION: Never connect a brushless motor's 6-wire sensor harness to ESC when wired to a brush-type motor! If ESC is powered on while in Brushless-Mode, and is connected to Brush-type motor {phase wir es shorted together} & a battery pack, a 6-wire brushless motor's sensor harness is connected to ESC, and ESC receives a transmitter's throttle signal, severe ESC damage will occur. P5 qs w PLEASE NOTE: This page contains optional Advanced Programming items!No further adjustments are required. (but don't worry, you can always reset factory defaults by performing the One-Touch programming again, so go ahead & experiment--that's why the programming is in there, right?) Throttle Profiles 1, 2, 3, 4, & 6 can be independently customized to fine tune the speed control to feel just the way you like it. The GTB lets you adjust the following software parameters: · Minimum Brake/Drag Brake Percentage--1 of 10 settings. · Braking Type--1 of 2 types of braking styles (standard Constant Force braking or DRAG BRAKING where braking is applied during neutral). · Drive Frequency (Profile 6 only)--1 of 7 Drive Frequencies from 1. 5 to 11kHz. · Minimum Drive Percentage--1 of 5 settings from 2 to 12%. to customizing profiles 1 -4 or 6: With ESC on & connected to a charged battery (transmitter ON or OFF): 1. IF TRANSMITTER IS OFF, DISCONNECT ESC FROM RECEIVER Remove input signal harness from receiver to avoid radio interference. 2. MAKE SURE THROTTLE PROFILE 1-4 OR 6 IS ACTIVE If you are not sure what profile is selected, follow the procedures in `Throttle Profile Selection' to check or select desired profile. Remember that you can not access the Brush-Mode (Profile #6) without disconnecting the brushless motor's sensor harness from the ESC. Note: there is no time constraint during selection process of custom parameters. chart: gtb soFtware Flow chart: RED or RED & GREEN press & hold brake: to adjust minimum brake: (or re-activate std-style brakes) a.
