Azhaguvel,

Balsa is also fragile and will break if crashed. The question is how much reinforcement is needed to produce a structure that is light and strong.
I have been using biofoam sheets for building and no issues so far ( apart from crashes). I have used biofoam for AUW of about 1.2 Kgs

i don't have knowledge about bio-foam, haven't even seen one Tongue.
But thermocol means the normal ones we find in shop, can that one also be used?

No, i don't think that will be strong enough. However, if you find high density thermocol, that would work.

Normal thermocol is too soft so it will need more reinforcement to make it rigid for wings, but yes it can be used

yes, ofcourse you can. But having a airfoil improves the stability and performance.

Yes you can use thermocol for making wings its quite economical and light. Paper the thermocol to get the profile u require and add a spar at 1/3 from the LE to prevent flexing of wings.
