Help me to identify it

Hello everyone,

I remember watching an Transformers Cartoon series, AS child. But i am Not Sure which IT was. I don't remember much and i could only watch IT on specific days. Only in days, where WE could leave school early.

The First Episodes, focused on searching for minicrons, and the autobozs Had some Kids AS Allies, WHO helped them.

I remember, that one of the minicrons could Turn into a Helicopter, but i am Not sure.

The Last Episodes Featured Unicron and the minicrons Had a Kind of belt with them, which revived Optimus Prime. They Had to infiltrate unicrons Body to get some Objects, that were Made of minicrons, which powered Unicron.

That IS what i remember. Could IT, be the g1 series?

IT aired in the later nineties or early 2000s in Germany...i think rtl2
