If you had it put away for a while, and it was ok before it was put in storage.
Then later you take it out again a few weeks later, and it revs too high.
The settings are ok. Nothing is broken.
But the fuel has dried and gone thick in the fuel lines, partuially blocking the outlet at the tank base, and the inlet at the carb.

This fuel blockage reduces fuel flow, which is the same as screwing the needles in to lean out your engine. The engine revs higher, gets hotter, can cut out when going fastish, is harger to start when cold.

Replace the couple of inches of silicone fuel line from tank to carb.

So try opening the main needle 1/4 turn to compensate for a narrowed piping at the "corner joint points".
.
If absolutely necessary ... open the idle needle 5 minutes approx. Write that down for later when you want to return the settings, if you are unsure how to tune accurately.

You need to wash out the jelly-like fuel at these particular points, or blow them out with compressed air. Close your eyes, nose, mouth, if you do this because a potentially harmful fuel vapour will be blown away from the area by the compressed air.

When the residue dissolves away, more fuel will get to the engine and you will see the car begin to run rich, and you can put the needle setting back where it belongs.

Coolwings is right, BUT

Did you have everything switched on? Batteries charged?

(Maybe a silly question, but it happens to everyone..:p)

Agree with Coolwings as well.
But I was just about to ask are your batteries fully charges in the handset and receiver pack?

Ye,as coolwings said all this i dont have the time.would i be able to drop it down to you coolwings?

coolwings

I would be there tomorrow morning, but leave it there and I can see it later.
Assuming the batteries are fine, it just needs cleaning out.

I bought one, complete rubbish and seen them driven also complete rubbish. I remember at one stage when no one was buying them the owner of cen edited the cen website calling americans every name under the book etc.

Recently cen are after getting serious about rc, the likes of the matrix buggy etc.
But avoid there 1/10 scale fun factor series:(
