That's awesome!

Any idea on which servo is compatible with the board?

I usually use Futaba & GWS servo with TK board.

Dear All,

We are now glad to announce that we have new member of TK22 & TK35 series, TK22G1, TK22G2, TK35G1 and TK35G2 which are mainly targeted in modern tank application, major new features on these new member are:

-Vertical Gun Barrel Stabilizer( TK22G1, TK22G2, TK35G1 and TK35G )
-Horizontal Gun Barrel Stabilize(TK22G2, TK35G)
-Auto Load Position( TK22G1, TK22G2, TK35G1 and TK35G )
-Engine Deck Level Detection( TK22G1, TK22G2, TK35G1 and TK35G )

Thanks for unified software platform concept, all existing TK22 and TK35 can be sent to us to upgrade to G1 or G2 version.

Both G1 and G1 will be released by end of Jun with new TK22 production run. Overview information are added to TK22 web page, we will add more installation information as soon as we can.

Thanks,
Clark

Hi Clark,

Just asking if the TK22 can take in 12 V?

I want to use the Clark-Benedini TBS mini (w/ 15 w amp) as direct replacement to control 1/6 RC Stuart and make use of your board's top notch functionality and mate with Benedini's top sound generation capability.


cheers,Rey

Hi, Ray,

No, TK22 is not designed to work at 12V.

Regards,
Clark

You can power the amp off of a separate 12 volt source. That will give you the volume and clarity you are looking for without risking the TK 22..

I hook my 'Battle armor' amp on a 9v battery to save Space, Ear cracking output. Love the Clark/tbs/ extra amp setup

Another option is to use a "dc to dc step-up adjustable voltage regulator"...They are inexpensive and works very well...I've been using them to power the resistor element of my smoke units for a while...http://www.ebay.ca/itm/DC-DC-Adjusta...82e3cac&_uhb=1

I thought the same way too, but too busy to test noise figure of this configuration till now, thanks for the information.

Thanks for the information gents, it will all be very handy.

Looks like the Clark board can handle the stock 12V stuart motors (http://www.customrcmodels.com/M5Stuart/id73.htm) as per Willy's research. However, lowering the V supply to 7.4 decreases the rpm, rendering a less mobile tank. Hmmm, whilst its tempting to retain the rpm (9800rpm) by going higher V (12), i could fry the board. By any chance Clark you have a dispensable board at your disposal that can be of use to research if it could handle 12V motor and 12V supply with minimum modifications (i.e., fan, or additional heat sink)? If the clark board be able to power it up, i'm sure other 1/6 stuart owners might be able to get a chance to check it out for their tank too.

Dan, does it imply that with respect to the 15 W amp, that power supply increases sound output and clarity? Is this a linear or exponential increase? II'm guessing at 18V, it would be awesome. I could then use the stock Stuart 12V battery to power the amplifier then whilst a 7.4 Lipo for the Clark board. Otherwise go with Strmnd54's suggestion, powering both Clark (via V regulator) and Benedini' 15W amplifier with the stock 12V battery.

cheers,
Rey

Hi Rey. If your stock battery is 12 Volts and you need to bring the voltage down to 7.4 Volts to power the Clark board; you need a "Step down adjustable voltage regulator" ...
http://www.ebay.ca/itm/NEW-LM2596-DC...5572844&_uhb=1

If your stock battery is 7.4 Volts and you need 12 Volts to power the audio Amp.; then use the " Step-up adjustable Voltage regulator " I mentioned earlier...
Cheers, Norm.

Hi Norm, thanks for the link. Yes, will be doing a parallel connection using the stock 12 V battery. One towards the Clark board via a step down V regulator whilst the other connects directly to the amplifier (much like an inverted set-up for tamiya tiger). That way, the tank retains it weight and runs quite longer. cheers, Rey

powering amp by step-up regulator is better.

I agree Clark, by going 7.4 and stepping-up V for the amp, I lost about half the weight of the tank.

Dual Tami KV1 speakers for engine sounds(15Wamp-Benedini) and stock speakers for the TK22.

The boards appear as though they're lost.

You will have to be aware of the ampere draw as well. Between the amplifier, and the other load requirements( gun servo recoil, track recoil, flash etc) you may find you are into the "Brownout" range. I am not sure how a step up regulator helps or adds to this problem?.

With all that room in the tank, it seems to me like you won't be hard up for room. So perhaps a 12 volt battery with a step down voltage regulator to the Clark electronics may be the answer

Audio amp needs much less current than track motor(~20A), a 7.2 battery + step-up regulator is better.

that is a really cool feature


Rey, I am pretty sure there is someone on youtube who details their clark/bendini setup

That would make sense. Some people like the idea of the sound system being independent of the drive system with respect to battery usage. Bottom line is 12 volts will give you a much louder cleaner sound regardless of how you get it to the amp. ( of course your amp has to be rated for this power rating). What I am saying is that an amp that can run on a voltage of 6-18 volts will be louder and sound better if powered by the higher voltage.

Rey is one of those guys, and has showcased at least two tanks with the Clark/TBS set up

Would this work for servos. I want to increase the servo from 4.8 to 6v

I'm not sure, but it should...As long as the input voltage is 1 Volt lower than the desired output. It would also depend of the current needed for those servos...
I've been using one to power the 24 Ohms 2 Watts resistor of my smoke unit...The output is set for 12 Volts ( meaning the current is 0.5 Amps), and remains constant from 8.4 Volts ( battery fully charged) to 7.0 Volts ( almost dead)...

That is totally amazing.

Uhg. Now I feel so obsolete with all my manual elevation control...
