Terminology

Ultrasonic ESC is the ESC block which switch FET at ultrasonic speed, make motor rotation extreme  smooth and quite. start voltage of ESC can also be adjusted for different type of motor.

Carefree reversing: Unlike some other control board, there is no need for TK series board to delay before being commanded to reverse, can go from full forward immediately to full reverse or vice versa
 

EPM ( ESC/PWM module) is peripheral which can be switched to ESC or PWM mode, allows the user to drive brushed motor or servo motor, in ESC mode, ESC port is enabled, can be used to drive brushed motor, In PWM mode, PWM port is enabled to driver servo motor, sound effect stopped when servo motor reach end point, TK40 has 2 EPMs for gun elevation(EPM1) and turret rotation/gun traverses(EPM2),

RealRecoil allows you to recreate real gun barrel recoil movement with single & cheap servo motor

Recoil Solenoid allows you to recreate MG/Auto cannon barrel recoil movement with Solenoid

V2 Smoker driver smoker fan/compressor speed is proportional to engine RPM and Load

V2  Mixer turning is achieved by reducing track speed and also increase opposite track speed to achieve smoother turning.

Adjustable Low Battery threshold cut off ESC output when battery voltage is lower than threshold, and threshold can be adjusted according to type and cells

Installation Guide

Set Upper Hull Functions (CN9) Mode to match your tank hardware configuration (HL AirSoft, TAMIYA Recoil or MG recoil),

Disconnect RX-18 and plug cables to the same connector on TK board,

Set Sound Volume to middle

Install a switch cable (for example, HL Smoke Unit Switch Cable) to SW connector( Switch Cable Port)  as power switch.

Because HL tank already have power switch on battery cable path, so additional switch is not required, just to use a jumper to short pins in SW Cable port or connect a switch cable and keep it switched on.

When high current track motors are used, such as 400/480 motor, power switch on battery cable path will not be able to handle, connect a switch cable (for example, HL Smoke Unit Switch Cable) to this port as power switch.

Connect a recoil servo to J2(Optional),

Rewire Air-soft unit if you want to elevate and depress gun directly, see "HL Gun Elevation and AirSoft Correction" section

(Optional). wire a 2.2 ohm 1/2W (color code: red read gold gold) in-serial resistor to turret rotate, elevation and airsoft motor to limit the current to protect FETs in case motor stall  occured.

Connect channel cables to receiver according to RC mode( See picture "TK series connector and pin assignments" ) . if you are not sure what mode you RC system is, just swap CH2 and CH3 and try again.

TK40 board has BEC( Battery eliminate circuit), can power receiver through channel cables, no additional battery is needed for receiver

Set CH1, 2 and 3 trimmer on transmitter to center position, Set CH4 trimmer on transmitter to most left or right  position,

Connect power adaptor( See FAQ )

Switch on TK board and transmitter, you should hear turret traverse sound. if not, please contact us.

gently move CH4(Multi function control signal 2) trimmer to center till turret traverse is gone.

gently move CH2(Throttle ) trimmer up and down if you hear motor hum sound.

Cannon firing sound should be generated and recoil servo should moves when move CH3 stick to most top position, if not, gently move CH3(Multi function control signal 2 ) trimmer up and down till it work correctly.

You are all set

Disconnect power adaptor and connect battery( make sure that battery is fully charged).

-Operating Angle: 45 Deg. one side

Power on GBS calibration - When power on TK60G2, GBS starts a reset process and must be kept stationary.

Adjusting gun elevation angle - The gun elevation V gain setting is used to adjust the amount of gun elevation servo angle to meet different mechanical setup. adjusting procedures are

-First to put TK60G board in IR programming mode.

-Turn GBS on and moves the gun barrel to horizontal position.

-Tilt the tank for 15-20 degree.

-First to put TK60G2 board in IR programming mode.

-Turn GBS  on and moves the gun barrel to horizontal position.

-Tilt the tank for 10-20 degree.

-Rotate turret in various speed ( from low to full speed), if elevation speed is too slow, increase slow gain a bit, otherwise, reduce slow gain,

-rotate turret to 12 o'clock position, tilt the tank hull about 15-20 degree in various speed, if elevation speed is too slow, can not keep up tank hull tilt speed, increase fast gain a bit, if elevation moves faster the hull tile speed and over the position it should be (overshoot), decrease fast gain a bit

-Power off TK60G2 board, remove jumper and turn power again to leave IR programming mode.

Adjusting turret rotation motor control gains -Turret rotation motor P , I  and D gain are used to meet the characteristic of turret rotate motor and design on your tank. adjusting procedures are as the following.

-First to put TK60G2 board in IR programming mode.

-Turn GSU on

-Rotate tank hull from stationary to low speed, if turret motor does not start as quick as tank hull rotation, increase I gain a bit, if turret motor runs too fast (overshoot) , decrease I gain a bit.

-Rotate tank hull in various speed( low, middle and full) , if turret rotation speed is too slow, can't keep up hull rotation, increase P gain, otherwise, reduce speed gain,

-Stop tank hull rotation from various speed, if turret stops too early, decrease D gain, if turret stops too late increase D gain.

Settings of TK series board can be changed by a IR configuration remote as IR command transmitter, and TAMIYA battle unit(TBU),  Heng-Leog battle unit(HBU), or our IR configuration line as IR command receiver.

Steps to change settings:

STEP 1: Turn power off, Turn power off, Turn power off,

STEP 2: Plug programming line/TBU/HBU through TBU/HBU base into CN2 Infrared Port ,  

STEP 2: Install a jumper to J2 as shown below, Turn power on,

STEP 4:Refer to function table listed below, point IR configuration remote to TBU/HBU/Programming line receiver, and press the button of setting that you want to change,  "*" sign in function table means the default setting that is programmed in factory
