guys please help me out of this. i want to built  an r.c plane ? what will be the cost for a basic model of an r.c plane? 

* Building material (depron or thermocol or epp or epo or coroplast) Most of these are not available (Check out http://www.kinetichobbies.com/) , (RCDhamaka.com), (RCBazaar.com)

* Building plans (Start from easy first. Search for trainer models like blue baby or Sky King) (A high wing slow aircraft should be ur preference as it will give you ample of response time)

********Electronics*********
* 1 Brushless motor and a prop (It could be a pusher or a puller) (RS 500+)
* Esc for motor. It should be atleast 5-10 amps more than the need of the motor (RS 500+)
* 2 or 3 Servos To control control-surfaces(Ailerons/rolling, elevators/pitch/Going-up-down and rudder) (Rs 170+ per motor)
* lipo battery and charger. Be carefull with the battery (depends on the weight of aircraft and power required because high capacity will be higher in weight. and carrying higher weight will be inefficient So it wont increase ur flying time too high)

* Transmitter and a receiver(atleast 6 channels) (Most important) (Starts from RS-2850/- Flysky CT6B) But as per forum people go for Futaba Or JR(expensive ones)

*******hardware**********
* Cutting knives and blades (rs 160+)
* HOT GLUE (400rs for hot glue gun and rs 10 to rs 15 for hot glue sticks)
* Packing tape(Give a coating to ur aircraft using this for extra strength) rs 85 to 500 rs
* Push rods to connect servo motors and control surfaces using CONTROL HORNS(rs 35 to 70 for 5-6 push rods and rs 25+ for control horn per peice)

Lots of patience

And knowledge and passion. Start watching Flitetest videos Beginner Series. And "Maker Hangar" on youtube

And also search for CG ie Center of gravity(Dont know much about how to calculate this. even i am doing R and D on it)

Sometimes you will need to solder a few things. So get a soldering setup as well
You may need to be careful about the connectors

Hope these points will help.
(And pls do R and D on above points to get better picture of what i am saying)

For a Beginner only.
If you have around 2500 Rs other than the costs of building tools and TxRx, you can make one.
1.Motor = 600  to 950 Rs
2. Esc - 600 to 950 Rs
3. Lipo - 300 to 500 Rs
4. Servos - around 200 each
5. Landing Gear - Around 160 Rs
6.Bullet connectors*3 and heat shrink tube - around 250 Rs
7.Propeller -80 Rs
8.If depron 200 + If Thermocol around 100
------------
TxRx- 2600 and up
------------
Building tools including Hot Glue Gun

"Slowly " is another very good beginner model.

Turnigy 5Ch TxRx ( costs around 2700 Rs) is  very good for a beginner ( 1.Very easy manual programming of channels at the flick of a switch  2. Light weight even a kid can carry  3. Needs only 4 rechargeable batteries which lasts much longer than in a Flysky )
