@shyam hembram,
With due respect to Gunnu's response...
As usual, you forget that the kv (rpm per volt) has nothing to do with the power of the motor.
Remember that the kv is the rpm it will run per volt withuot a prop.
Putting an 8x6 on that 2600kv motor of unknown wattage, is like towing a tractor with a Scooty!
Unless it is a very powerful motor.

Try a 6x3 prop.
Please try to understand that you need to know the power rating of the motor.
If the kv is low, it can take a larger prop.
If the kv is high, it needs a smaller prop.
But how much prop it can take depends on its power

I have 3 Turnigy 2826 motors that look the same, (nearly same power) but are 1000, 1400 and 2200kv.
They are used on different planes with different props.
10x6, 9x5 and 6x4 respectively.

Statements like 'it doesn't spin ( very very slow)' are unscientific.
Does it spin, or does it not spin?
If it doesn't spin, you've jammed something.
If it spins 'very very slow' what would you expect if you put a large prop on a heli tail rotor motor?

Your query contains its own answer. It spins without prop, but slows/stops with prop.
Obviously the prop is overloading the motor!

iyer sir..

thanks Iyer sir ,I haven't tried it with 6inch prop, now I got the math,but it was a 2s battery that's why I thought of using 8inch prop
