Specs of the IC RX-2 and TX-2

[vicman]

Any one know the brand of them? or has the specs? i want to have them to know each pin fuction, maybe we can improve a lot the cars if we get the info... I need at least the pin dessignations of the chips

Vicman I can give you photos of each one.I don't know much about electronics.The relay kits seem the cheapest and easy way to get around the limits of the reciver and transmiter.Tinracers.com (http://www.tinracers.com) Have a ready made relay kit for $2.00:D

The reciver

[vicman]

Well thanks a lot for the pics, but i wanted the specs of it, or even the maker, i dont recognice the logo printed on them.
I have 3 relays mounted on mine, i mounted the 3rd relay to pin 12 (if i remember correct) thats can be used with other button to have a extra boost of speed with a 3rd cell, one of the best mod one can do!! but... i want to know the pin codes.. if i can get 5 stand alone signals as i think it works like that i can multiplex them and make the car much more reliable!

Take a look at the following link:

Take care that you have to download from Adobe the "Traditional Chinese Support" to be able to read the documents.
Good base for understanding Microcars circuits and maybe creating new applications.

Have fun

can you give instructions or direct me to where you found them for making the boost funtion
I have two relays in mine now from tinracers and I love it I cant amagine it with a third cell (though I was planning on doing it anyway)

Yeah so if you can help me with that

I cant find the boost instructions anywhere on carmoworld

Try this one then :)

ok wow
it looks more complicated then I thought it would be
mabie I may just add a 3rd cell into the normal circuit
You can do that right???

Well, if you're not affraid to fry your PCB or your motor case, you can give it a try :)
Even if the boost mod (the one with the 3rd cell) seems a little bit complicated, it is worth the pain cause you'll have a turbo button on the remote giving you 2 speeds forward and then, a better control of the car.
The only thing I hate is having that 3rd battery ruining the look of the car. IMHO that mod looks better on a truck body (mod it as a pick-up, and put the 3rd and even the 4th cell in the back...that's great for wheelings too:) ).

Another boost mod is based on capacitors (no extra battery added). But I don't have the schematics here (should be easy to find some with google though).

[Lord_Nick_D]

does it do wheelies
what is the setup for that

[freed]

Well, the setup for the turbo boost uses 1 more battery (and a switch on the remote)... You can use 1 or 2 batteries in fact, it doesn't matter that much (more bat, more po').
Then depending on where your place those extra batteries in your car, the thing can do wheelies...
Some Auldeys modified for dragster races have anti-wheeling bars mounted...
