Controlling two AA batteries with 433 MHz transmitter and receiver

So guys I'm working on a little project which involves controlling two AA batteries. I'll have the batteries in series to get the power I need so there's only two cables to both batteries.

I'll need to be able to control the batteries with some sort of switch with the 433 MHz transmitter and reciever. How could I do this? I have no clue what to do with the wiring or the code.

Thanks

What does "controlling two AA batteries" mean, please?

I'd like a small electric engine to be controlled in the end (on an rc car). So that's why I need the two AA batteries. I could use the arduino 3.3V but the Amps are way to low to crank the engine.

If all you need to do us turn the motor on/off in one direction at full speed then use a relay

Yes! Has anyone here done it before? I have no clue what I have to do.

Thanks
