HobbyKing Red Brick 20A ESC
http://www.hobbyking.com/hobbyking/store/__25112__HobbyKing_Red_Brick_20A_ESC.html

yep it should work, i am using same motor with 20A esc does not get too hot, but yes bit warm not very. But its very good combo

thanks so can i buy it from hobbyking?and can you recommend that which battery should i use.i want the cheapest

you can get same motor from my webstore http://www.quadkopters.com/product/quadkopters-qk750-brushless-motor-750kv/

i dont have ESC its out of stock, will be back in a week time or so. Battery also i have please check website.

About battery from HK i am using just one zippy flight max 11.1v 4000mah and it gives good 12 mins of flight

Load on Motor and ESC will depend on the prop, it is loaded with.
In Electrical Engineering the Basic Rule is LOAD IS THE KING.

You can easily overload by using oversize prop in diameter and/or pitch.

means i can use it

You can use  a higher amp ESC with a manufacturer recommended prop and motor combination..
Using a higher amp ESC will never harm a ESC but the advantage is the heat produced will be less.

You can use it with limitation imposed by Prop. Do not use prop except 11x3.8 or 10x4.7 to be in safe power range. More safe prop is 9x5 prop (Static thrust near about half).
You can cross check the power requirement and hence the current from below.

Kalyan, incomplete info, what about battery ? did you check with him how many cell batt he is using, 2S, 3S , 4S ? Depending on the batt used for a particular KV motor the prop will be different, higher the number of cells, more is the voltage and therefore more is the RPM and like Kalyan says More load. Most motor data gives you what prop to use with what cell.


@Kalyan

More Safe is also called Safer , a comparative statement

So I stop posting now till new plane build thread. Don't blame anyone.

i m using a 3s battery

11x4.5 is ideal and let me tell you about DT750, it is one of the good motors, the shaft length is high though and needs to be trimmed (If you want to that is), 11x3.8 is good too, both will give you ample power for a tri
