Instead of going for 1450 kv.
go with CF2822-1200 kv and 9inch prop.

Re:
Khan007 firstly ... Know the model ... Is it a glider ? Scale ? Jet ? 3D .... This will decide what thrust and what speed is required to keep it airborne ... And then finalize the power config ...

Khan , you have place order or you have it with you.
If you have just place order than , you can request them to change as they cost same.

If you had it with you , then no choice , make smaller plane with weight less than 500 gm and use on it.

If you really want good thrust of nearly 800 gm than go with other motor. CF2822 will also not give you 800 gm thrust , but can fly your plane.

Re:
Like for a 800 gms  jet u will need a small prop is it has high wing loading and needs speed more than thrust to keep it air borne ..on the other hand if its something Like a slow stick u will need thrust and not speed so need a bigger prop ... And all this will dictate the motor battery ....

Re:
Done this from some plan ? Wings don't seem to have aerofoil so won't have lift not a it will be tough getting it airborne as will require a large high pitch prop coz its only speed thats going to keep at aloft ..... Correct me if I am wrong ....

This model is similar to Moss glider model i build. Only the wingspan is different. Mine was around 40" and wasn't having airfoil shape. I used 1200KV motor for it with 20A ESC and a 2S 1000mAh battery and GWS 9X5 prop.
I don't know why your model is so heavy... 800gm... since, it seems to be a slowstick...
