Engine Problems, help me

Hi, everybody.
I have a problem with my Rody .12 and my sx.12ss (novarossi)
When my car roll over, the engine stall immediately.
What is my problem?
What is wrong with it?

Thanks for you time

chances are it didnt "stall", probably what it did do is run out of fuel.. for it to run longer while its on its lid you can lengthen the fuel line between the engine and the tank..

If my car stalled when I hit something, most likely it's a clutch problem. You can also check yours

Thanks.
I will be cheking it the next week.
