Ok I know that kv means the rpm per volt of a motor.
I want to know a comparison between a low kv and a high kv motor.
For example I know a low kv will reach a particular rpm at a greater voltage than a high kv motor, but what about the current draw??
How does the kv rating affect the current draw of a motor??

@ Kavinprakas

It depends on the type of plane you want to build and the materials you are going to use.

@kavinprakas,
It depends on the type of plane, as Swapnil said, and on the wing loading

I don't know how you assessed the all up weight as 700gms, but if you're going to build a trainer of say 2sqft wing area with an airframe weight of about 500gms, then you can consider this:

Emax CF2822 of 1200kv, any 20A ESC, 3s lipo of 1000mah, prop around 9x5.

There are many alternatives, but this is one of the cheapest.

If you are interested in the theoretical basis, you can look at this:

Don't use a motor there. You would need a 50-60 cc engine!
