Now i need your help about :
1.soldering the brass pipe is hard cause when i make a joint and start to make another one the first joint gets heatet up and melts ... any solution ?
2.I need a small emough recever and transmiter to fit in the car
3.Can i just plug the servo conector to the recever for it to act like a esc whit the motor and gears ?And i will remove the servo pot ofcourse.
4.Any ideas how to make it 4x4 cause i cant order already made parts from germany and i have to make the steering myself.

Thank you for your help and pls reply in english Laughing

The end.... Smile

Just took a look at your components and I really think that they are too large.
You will need a real Micro-Servo like

You can also take it apart and use the electronics for a speed controller. But better is a real speed controller like
http://www.kkpmo.com/products/RC/index.html (Poland). There you can find a lot of usefull things for your project, too.

BTW:
Metal bodies are normally too heavy for crawlers. The cog will be to high. Try to get a plastik body, that will make your project a lot easier.

Yeah they might bee too large ...
Can you recomend me a setup (transmiter recever esc ) from microantriebe or can i use the one from the rc helicopter? and if i make my own esc how do i conect the batery ?

Thanks

I think they have only one receiver:

I personally prefer this one:
http://www.bidproduct.com/more/cartview.php?id=1791 (currently sold out)

But a normal Heli-receiver should work, too.

For speed controller I usually take the ER300.

This is how we assemble the electronics:

What does this "Ladebuchse" mean.And can i use the transmiter from my other rc car and just swap the recever cristals from my old rc to the project will it work? Cause my radio from the old rc is 27 mhz and this is for 40 or it depends from the crystals. OR how can i use my heli recever and transmiter?

You simply cannot use a 27 transmitter with a 40 receiver. This does not depend on the crystals but on the basic electronics.
For a 40 MHz FM receiver you need a 40 MHz FM transmitter.

"Ladebuchse" means "charging port".

BTW:
Your heli electronics look like they come from a cheap toy helicopter like a pico-z. Seems to me that it works with an infrared transmission. This can of course not be used with any receiver I showed you as they are based on radiocommunication.

I am not sure if this cheap heli esc ist really usefull as you cannot connect a servo. You can control a motor, though.

Maybe you should take a look at the pictures of this thread:

It shows how to build an 1:60 Scale full-proportional micro car.
