Questions on power.

[Chang]

Hi Mark and all of KT owners,

It's about the time to connect the motors, sound and smoke packs for testing.

Before plugging in this connector, I would like to be sure which line is the signal line? The green one or the blue one?



My local hobby shop said:
(1) The blue one is the signal line, and the green one is the negative line, which is based on Tamiya's code of colours.

(2) It is similar with the Futaba's code of colours, only the signal line is white there. Black line is, off course, the negative line.

Mark can you please advise me about this question?

Meanwhile, if any of our knowledgable KT owners also knows the answer, please give me a hint too.

Thanks!

Hi

The green wire is the negative or earth wire. The blue wire is the signal wire.

Thanks Mark for the answer.
Another question on the headlight: Is a bulb or LED used? What type of power source used here (24V or 12V or another independent battery?)
Thanks!

Hi

The headlamp is fitted with a 12 volt bulb. Our intention is to supply all KT option pack customers with a a small pack containing the wiring, a rear/internal light and the instructions for connection to the auxiliary module. This would allow lighting to be controlled by your radio. These little packs will be available in a couple of weeks and will be free of charge.

Hi Mark,

That's great news, and it has come just at the right moment for me. I was just pondering the same question as Lerh Chang, with the addition of the convoy light

Hi Mark ans Gill.

As Paul says great news another little addition that will make an already spot on electrical system that bit better still
Well done and thanks again.

Hi Mark and Gill,

Today I have received the wired loom of the headlamp & convoy light bulb.
Thanks for the generous supplying.

There is no instructions for connection though. But it shouldn't be a big problem. Thanks again.

Hi Guys

For you who has an older tank,and wanting to turn some thin on instead of useing a servo and switch, you can allways use this very nice bit of kit, its been around for a bit on the plane and helly front ,and comes in 3 sizes, great for turing things on/off and this one's at 10AMPS so great for smokers ect.(but allways check your items out put first)

Hi Mark,

Well..... I still have a small question: Are the 2 female plugs of this wired loom supposed to connect to the Auxiliary Module? According the instruction manual they are. But I am not sure to which 2 male plugs on the Module?

A brief diagram or photo will be helpful.

If anybody willing to help, it'll be appreciated too.

Thanks!

Hi

If you have followed the instructions and assembled your modules as shown in the photographs, there are only two male connectors left unused on the auxiliary module. Connect your headlamp wiring to these. Connect the bare wires at one end of the loom to your headlamp, and arrange the pre fitted rear light at the rear of the hull. Control your headlamps using the remaining control input on the aux module and an available channel on your transmitter. This will be channel 7 on the Futaba 7C set. You will need to set the EPA for channel 7 to 0% in one direction, as described in the Futaba manual. You will also need to fit a servo "Y" lead to channel 7 on your receiver for attachment of both the power supply and the control wire going to the aux module.

Hi Mark,
Thanks for the reply.
I will try to sort it out later, as I will be using a Sanwa R/C 8-channel transmitter:

"This will be channel 7 on the Futaba 7C set. You will need to set the EPA for channel 7 to 0% in one direction, as described in the Futaba manual. You will also need to fit a servo "Y" lead to channel 7 on your receiver for attachment of both the power supply and the control wire going to the aux module."

Hi Mark,
Can you please help me to clarify two questions:

(1) Since both the headlamp & convoy light are for 12V power source only, how do they work on this 24V power system? Does it mean the 24V power source is reduced to 12V for this purpose?

(2) Is the same situation applied on the 12V-based Benedini sound system and the smoke system?

And one more help needed is: Is there any socket on any power module to plug in for powering two 12V fans I'll be installing them to cool down the 2 drive motors?

Thanks!

Lerh Chang

Hi Chang

1 The headlamps are 12volt. They are wired in series. Two twelve volt devices wired in series require a 24volt supply.

2 The benedini sound system in Armortek products is 24V.

3 Armortek do not use the benedini smoke system.

4 THERE IS NO 12VOLT OUTPUT.

Armortek do not make any provision for 12V devices. Mixing voltages is not good practice. Twelve volt devices on equipment this size require double the current for the same power, and would require twice the cable size and significantly increase the risk of cable melt down. Once again Armortek do not use, or provide for 12v devices. All Armortek equipment is designed for use on 24Volt.

I hope this makes things clear.

Mark

Hi Chang

You dont need fans to cool down the motors they will be fine as they are mate.

your batteries will need recharging before the motors get even warm

Hi Richie,
Thanks for the advice.
I have already installed 2 fans above 2 motors a while ago. So just let them be there...

Maybe the Amplifier Module needs a fan, which becomes hot during operating on its left side, where the sounds' amplifier sits.
