New Accessories update: IR Programming Line, a 5P connector wire with IR receiver & Red LED indicator, and a 2.54mm-pitch Jumper, for user who are not doing IR battle, but just need to change TK20/22 settings.

Q: I accidentally shorted speaker wire and now had barely any sound, everything still works but hardly any sound.
A: A FB might be damaged because of over current, please remove it and short its two pads by solder or wire.

Q: How to interface TK22 board to external amplifier
A: This picture shows the pin assignment of external amplifier in this example, Battery + & Battery - are power input pin, SIN+ and - is for audio signal input, SPK+ and - is speaker port.

First to disconnect black wire from HL Volume control board and isolate it with tape, wire a 2-P, 2.54mm pitch connector wire to Volume control board as shown below.

Then to power amplifier by battery or additional 11.4~12V battery pack, normally, higher the power voltage, higher the max. output power to speaker, just make sure ground of TK board & additional battery pack are connected firmly. In this case, we just get power from TK22 bottom side.

Finally, connect power form TK22 to Battery+ & Battery - pin, connect 2-P, 2.54mm pitch connector wire SIG+ and SIG-,and then connect sparker to SPK+ and SPK- pin.

Q: Do I need noise filtering capacitor on motor?
A: Yes, it's needed to prevent back EMF to interference TK20 board. All HL stock tank already have it on motors.

New Product info:

.

-Tips:
--Kijk of er noise filtering capacitators (gele dingetjes hieronder) op de motoren zit. Anders blaas je de FETs op.


--Zorg ervoor dat je een zekering van 10A in de hoofdleiding hebt zitten om eventuele schade te voorkomen bij onjuist gebruik.

Hallo, mag ik even vragen hoe deze op de juiste wijze te solderen. De plus en de min aan de kabel solderen is goed te zien dus geen probleem maar de andere uiteinden waaraan soldeer je deze, aan de behuizing of ergens anders. Het is lastig te zien.
Bedankt alvast

Zie ik dat juist, dat de elevation – unit eruit kan en dat de bolle gedeelde van de recoil-unit weg gesneden kan worden. Hebben jullie misschien een foto war het goed te zien is.

Asiatam recoil unit installation:

STEP1. Set Main Gun Function Mode to TAMIYA Recoil MODE,

STEP2. Connect Recoil motor + to 3rd pin on CN9.connect motor - to 4th pin on CN9.


STEP3. Connect detection SW to 4th and 5th pin on CN3 or via the plug (Yellow and brown wire) from HL HIGH-TENSION FLASHER

Q: Airsoft unit fires continuously and have no cannon sound.
A: When main Main Gun Function Mode is configured to AirSoft Mode, TK22/20 start to drive AirSoft motor (thought CN9 3rd &4th pin) when fire cannon command is received. when Airsoft just fired, Airsoft switch is closed , Tk22 knows it thought CN3 Pin4 & Pin5. and then stop to drive Airsoft Motor and start to generate cannon. So in order to make it works properly, AirSoft montor need to be connected to CN9 pin3 and pin4. AirSoft switch connector to CN3 Pin4 & Pin5.



You can simply test it by a tweezers, to short and release it will stop AirSoft motor.

Q: How to avoid damage that caused by short circuit to the board?
A: Damage can be prevented by using a current limited power adaptor as power source, first to find a ~6V, 400mAh power adaptor, 1K 1/4W ohm resistor, LED and a motor cable(from HL cable Set)



Then connect + wire(with white strip) from adaptor to red wire of HL cable, - wire to black wire of HL cable, adn wire resistor and LED as the following to act as indicator.



Each time, when you did some modification on circuit or after installation, use this as power source fist. plug connect each by each, and LED will be dimmed immediately if any shortage in circuitry and not thing on TK board will be damaged because power can only supply low & limited current.

The board might be act very strange when it's power by this, such as motor can not moves will, cannon fired unexpectedly when turret rotation sound comes up, these are quite normal because current is not enough.
