when power begins motors all start at diffrent times

some one please help im new to this hobbie and this was my first  one ive spent over £200 and now im stuck

You probably need to calibrate the speed controllers to work with your radio system.

Tell us what quadcopter you have, what the speed controllers are and any other technical details you know and I';ll be able to give more specific advise.

That';s how i calibrate my speed controllers but i have SimonK firmware installed on mine. Yours may be slightly different, depending.

Unfortunately spending over £200 on a quadcopter does not guarantee success. You have to learn to understand how the systems work to use them safely and well. The easiest way to do this is to build it yourself. Multiwii flight controllers fly great - once you understand them well enough to get them properly setup and PID tuned. The learning curve is steep.

are you familiar with uploading a sketch.
multiwii v2.2 has an option to upload calibration for escs..

The multiwii ESC calibration routine works very well if you know your way around the arduino software as fruitsalad says;
