Help needed, battery conectors

[brisbaneracer]

hey everyone, i just bought a TA-03F 97' WRX off ebay. It has been wired with Deans ultra Plugs on the Novak Rooster ESC and the batteries, but my charger is a Tamiya style plug. Should i convert my charger to deans style or go back 2 the tamiya style?

Car specs

TA03F Chassis

Fantom Factory Modified 10 turn triple wind

Novak Rooster ESC

Sanwa RX-201 Reciever

thanks

Heres a pic of the Reciever and esc and the whole car

deans are way better, i have them. they give you noticable longer run time and slight performence increase. and an added bonus there much easier to remove than tamiya plugs.

[tt-01owner]

o ya i forgot to tell you a novak rooster esc cant handle a ten turn motor.

Solder on both, Tamiya connector and Deans, one way or another you will have to charge someone elses battery and most people have Tamiya plugs.

Just remember this doesn't mean you can now charge two batteries together.[]

Be very careful putting 'double' plugs on... the charger side

will need a Male plug (exposed pins) which is very dangerous

to leave swinging around uninsulated.

You're better off building some "Adaptors", Tamiya to Deans.

[Incredible_Serious]

I agree with wise old sage Willy... I have both Deans and Tamiya connectors on my cars, batteries, and chargers. In order to be able to use all my options, I made up a pair of adapters. Deans to Tamiya, and Tamiya to Deans. This way, I can connect any battery to any car, and charge any battery off any charger. Sure, there may be a slight performance hit due to added resistance of the adapter, but I'm not battling for sheep stations. If I was, everything would be hard-wired ;-)

Well thats gay if it cant handle a 10 turn motor, will it work at all? it has a heatsink if that will help.. what kind of ESC can handle a 10 turn ?

Well, It probably will work, but at the risk of burning out the ESC. I wouldnt do it.

You will have to get an ESC with a motor rating of 10 turns or less. At about this motor rating, most ESC are rated as "Unlimited". A cheaper option would be to just buy a new motor that your ESC can handle.

I would also stick with the Deans connectors, as they are far superior to standard Tamiya ones, especially running modified (10 turn) motors. You can buy "cheaper" versions of this style of connector. Ive used them, and whilst Ive found the male plugs are not as good as the original Deans, they are still Ok for chargers etc.

I'd say a 10 turn would be a bit hot for a TA-03 to be honest, it isn't the most efficient car ever. Also the motor is fairly enclosed so heat buildup could be a problem even with a brace of heatsinks on the motor.

[brisbaneracer]

what motor would you recomend for the TA03F chassis?

[Dephcon5]

TA03 motor in my opinion shouldnt go much lower than a 17 or 15. 15 being the hottest I would run personally. However, a good stock like the Tamiya TZ or the trinity P2K will power that car nearly as well as a cheep 17 mod and you can run virtually any esc since its a stock wind motor. I run the P2K trinity motor and find it works very well for speed and run time. They dont run too hot either.

Thats just my opinion... I could be wrong.

I do of course agree that high quality plugs is an improvement over the Tamiya plugs and that at perfomance may increase slightly, at least in theory. It's however not correct that run time will increase with better plugs. Quite the contrary in fact. The battery plugs are a part of the total serial resistance in the circuit and as such, higher resistance ("lower quality plugs") will actually reduce the current at a given battery voltage and as such increase run time. The opposite will be the fact with high quality (low resistance) plugs.

For now im going to put a stock 27 turn motor in it, im thinking now i have a spare 10 turn i should make use of it, i was going to get a new ESC and put it in the WRX then put hte Novak rooster into my MO1 mini, but since the 10 turn is said to be too hot and i dont think the mini can take a 10 turn then ill havto look out for a new chassis for it. tt01 perhaps

[audia4]

well on the subject of motors and tao3 im running a 12 triple and its plenty fast, and i have no problems. =)

tt01 is a beginner chassis and 10turn is actually also too hot for that, <13T are usually only good to make speed records but unsuitable for normal driving and even most pro racing, better try first some good 17-19T stock ones...

Thanks Guys, i went and got some Deans plugs and made an adapter for my charger. I left the 10 turn motor in atm because the engine plugs had been changed to female, i just wanted 2 c if i could get it working. I pluged the steering into 1 on the Sanwa RX-201 reciever and the Novak Rooster into 2. when i turned it on to set it the esc it would respond a little to my commands with no steering, the light would flash green then just go full throttle and the wheels span so fast that the tires stretched about 2 cm in diameter and threw off the inner lining. i go through the set procedure but it doesnt respond properly. How must i set up this **** thing?? Also what should i do with this 10 turn, any ideal speed chassis for it?

[brisbaneracer]

Im thinking of buying a Venom Racing Modified Motor 17 turn Double (17x2) to use with the Novak rooster.

VENOM RACING

MODIFIED (MOD) MOTOR

17 TURN DOUBLE (17X2)

Tamiya connectors will melt together when things heat up in a serious race. I didn't believe it either but I now speak from personal experience. Convert to Deans plugs and save yourself the hassle.

[fyra89]

Btw, my Tamiya plugs melted with a STOCK (27 turn) motor. Goodness only knows what would happen with a modified motor.

id="quote">id="quote">Hmm, I'm not so sure about that - the current provided to the motor is reduced, but if the motor is attempting to draw the current and the battery can provide it, then the battery does provide it, it just gets used up by the cheap connectors converting it to heat (and if the motor is thirsty enough they get hot enough to melt). As the heating of the plugs uses current, the amount of current the battery is providing remains the same, but it's just being wasted on the way to the motor. A bit like the battery dischargers which just use big resistors, they draw current which discharges the cells. If the resistors were smaller (like a lower resistance plug), then the battery discharge would take longer.

Of course there are a lot more things which effect the equation, like the quality of the cells, how well they are charged and so on. But in practice I have found that with the tamer motors like stock cans, changing to Deans or similar connectors has given me longer runtime. It might have been that the batteries were being charged better or something but I'm sure that better quality connectors make the car run more effeciently overall.

I = V / Rtotal where I is the current flowing, V is the voltage of the source (battery) and Rtotal is the sum of all resistances in a circuit since they are connected in series. Since R of motor, ESC and cables don't change, with worse plugs the Rtotal gets higher and thus the current lower. The total runtime is bigger but the percentage of power that is used by the motor is less, for example the car might be run 5% longer but motor has 10% less power. Hope that clears it up?

Cheers

[brisbaneracer]

Thanks guys thats good info! i managed to get the radio gear setup and the esc set, im going to run it tomorow when everything is mounted in and i am going to monitor the temp of the car when i run it. The car has deans plugs on the Esc and the batteries with bigger wires. ill post how it goes. cheers

id="quote">id="quote">Ah, I think I get it now. So if you update the plugs, because the power draw is the same, the runtime would be the same because the extra power which the inefficient plugs were using would now be used by the motor rather than the plugs? Therefore the motor would work more efficiently, but the total amount of power being pulled from the battery is still the same.. (I think that explains it without the math; I'm not very good with calculations []).

I like the look of Tamiya gold plug sets (http://www.modelpower.co.uk) which should give the advantage of less resistance, but without the hassle of having to changeover all the supplied leads on chargers and so on with Deans connectors. I also find that after time, Deans connectors can become very difficult to separate, especially on a cold, rainy day!

The best quality connectors IMO are the Corally bullets, but there is a danger of connecting them the wrong way round - Modelpower sell these connectors set into a plastic moulding which prevents this happening.

Almost there![] Actually the run time with good plugs is even less, as more current can flow through them, think of a narrow vs. a wide water/oil/air pipe [] Hope now its clear?

I have been running the 10 turn motor with the ESC only rated to 15 turn, the esc doesnt get that hot, but the battery gets super hot, the motor doesnt get hot at all. It goes well but not for very long, about 5 minutes or so. I am going to buy a 17 turn motor and a better battery and try that out tomorow. cheers
