prop:

http://www.vibranthobbies.com/planes-parts/airplane-accessories/propellers/gws-ep-propeller-rd-6050-152x125mm-green-6pcs-set.html

motor (will give thrust of 500 gm. if used with 6x4.  suited only for small 100-500gm parkflyers)

The space in the centre is only 6 inch so bigger propeller will not fit

I think you need to widen the space in the centre
Cause 1200 kv motor with 6 inch props... lot of thrust waste
Bigger props give more thrust (depends on the quality and type of the motor)
Look out for a suitable prop for that motor

I don't think a 1800 kv motor will give enough thrust to lift 500 gms with 6 inch prop. I believe you have to increase the size of your prop.

Hi,
If you have no prior RC flying experience, this may not be a suitable model to start with. Better to start with a Skysurfer or similar (RC Bazaar).
Pl see your PM. have sent more info.

@suyash,
Last month Col Sundaram's son built and flew a model similar to yours.
Send him a pm (param on this forum).
His build log is here:

Hope this helps!

You need a high KV one with lot of speed than thrust.
CF 2522 will give max thrust at 10 inch prop.
https://www.rcsportz.com/index.php?route=product/product&path=70_80&product_id=98

this one is lighter and gives around 400gms of thrust plus 3 blade 5inch prop will give you good speed on a 3S lipo maybe less than 1000mah.

@suyash,
Did you read the post about how much power?
If your motor is lower kv, all you have to do is use a higher pitch, like 6x6 or 7x6.
Please post the ID of your motor, to suggest prop size.

i think that you should give it a try then, coz you have reduced 60g on battery also and some on motor .launch it at 100perc throttle it will work fine.
