Hi Gaurav,
Go with the 'Turnigy 28-26-CQ 1300Kv Brushless Outrunner' along with Turnigy/LHS 18-20A ESC. It should easily airborne models in 300-400g range with the correct prop(try 7x4 or 8x3.
.
I have had a bad experience with the a motor similar to C2226 Micro brushless Outrunner 1800kv (21g). The wire broke off while I was trying to route them through the bulk head.
Anyway the first motor is given 5 stars comp to 4 star to the other one.
Did you consider Emax CF 2822/12 Or Blue Wonder kind of motor ? I find them easy to mount, give nice performance, and keep much cooler.
All the best and keep us posted.
