Hello everyone!
I recently bought an Rc Helicopter.
I was wondering whether i can change its body.
First,which material can i get easily for this Job and which one can be least expensive.
Please reply.
Thanks!
P.S- Is there any regular servicing to be done on Electric rc Helicopters,rotors,etc?

I guess you mean a canopy.  Not many people build them from scratch.  These small helis use moulded plastic ones, and people just replace them (if they can find the replacement).

A lot of people to get plain fiber glass ones for bigger helis, and do their own artwork (airbrush art).

Here is the famous Dubai based guy who does this for people in this region (not just UAE) :
