Hello, I am Ayush
I am making my first plane.
Its weighs roughly 500-750grams.
wingspan: 70cm
Made of Balsa

i am thinking of using a 1500-2000kv brushless motor with a 25-30A ESC.
I plan to run these by a 11.1V 2200mah LiPo battery
Also i want to use 5 servos here.

Is this configuration suitable for my plane?
please advice

You need two more parameters. What is the thrust/wattage of the motor ?  And what prop are you going to use ?

Please see this thread, as a starting point : http://www.rcindia.org/electric-power/amp-rating-and-motor-size/

I already have extra servos so i thought why buy more, i can do the retracting thing with the normal servo too. The canopy thing is still just an idea, i just wanted to have your advice on my maximum requirements.
Akky sir could you please advice me on motor and ESC configuration for this plane ??

Go through RCIndia Gems http://www.rcindia.org/rc-india-forum/the-rc-india-gems/
Spend some time reading this.You can find all related information there.

However your selection of motor, ESC and battery are all right. ESC is enough for motor and battery will give you 12-15 min. Transmitter is also ok. I will suggest you to go for atleast 50W charger like this
