I know its annoying to open a new thread for every little thing.. but i chose to make a new one as for simply one reason: I hope this one is useful and can be found in google once it is needed by someone else ;0)

So, to my small little question:
How to replicate or better how to make PPM Signals with the Arduino?
I havbe seen there is a pulse_out() function arround, yet i wasnt very lucky getting this one to work with my speed controller.. so might there be some simple way to make that all work - or is that stuff really so hardware depending, which i could not understand as you can buy FM receivers or speed controllers/motors in variing brands and fashion, yet it seems still to work all the time...

Hi Nachtwind, you want to use one of the many servo libraries for the arduino. there is a post here that explains the technology and has links to some code: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1232572239

If you want to write your own code, have a look at the source code for software servo library for an example: Arduino Playground - Servo

Wow Mem, great posting you directed me to - with that library there i was finally able to determine the values for my car to drive with :0)
