No spar?
I guess that will be asking for trouble...
This way of covering is time saving...
But for scale modelling this is not good...especially the ugly colour...

What configuration are you planning..pusher or puller?
have you planned fuse?

here is another photo

That a lot of dihedral...
It might stall...

yes but i have already flew with this wing it climbs good.i think (notsure) its climb angle is 40degree something

i am planning to make it a puller with 1000kv motor and 10 inch prop,with 1000mah 3 cell battery.and for fuse i will b using alluminium channel.

as i m a biginner every time i made a plane i just crashed .so i thought if i decrease diedral i will get more stability even without remote.i have alredy tested glide.it just glides straight covers almost 30feet if thrown from 15 ft height .hope it will fly after fitting the motor

Topalle . get book covering clear plastic film from stationary shop.It is strong and will shrink also.
another option is gelatin paper, it also shrinks well , but very thin.

@Rajesh did you sand the wing or used Hot wire cutter.

sanded the wing

awesome work then.

i build a similar plane named flyer 1. have a look

Progress...

I don't have much experice with foam...
someone please suggest a method of making control surfaces...

Well... to all the learned aeromodellers out here...... 

DIHEDRAL does not make the wing stall more or make it unstable.... in fact DIHERRAL is given to the wing to make it more stable....... 
  Please read about this on the net and then use it to your advantage

Somebody recognizes this?
