Which battery ?

[Balakrishna Reddy]

Looks like the motor kv is very high however that's not the problem but a 450 quadcopter should not have a 1800kv motor.
What is the propeller size?
What is All Up Weight(AUW)?

It would be very helpful if you can post a video or link to video.

What is the battery Capacity(in mAh)?

[Rcjabalpur]

I think so he has messed up with the motors , probably went with 18 size motors . The second possibility is the props , what size are you using ?

[Param grewal]

3500 mah
And the props are
10x4.5

Also , yesterday i burnt an esc  so ordered new ones

Sorry for bombarding with a lot of questions, but I hope you can understand that a clear picture always helps:)
[I am asking for components' brands because it will be easy for us to google for data like rated max current, thrust, etc. for that particular component.]

Let us know if you have any other observation as well.

Using an 1800kv on a 1045 props is overloading them,and that might have killed your ESCs. Try some smaller props ,maybe  8045 or lower I guess.

What size motor are you using ? 1800kv is a fast motor wont take those props very well ! Please please let us know about the motor .
