How are things in Brunei? Tower Hobbies http://www2.towerhobbies.com/cgi-bin...=++&search3=Go
carries some of the parts you may be looking for.

ModelSport makes some very nice carbon fiber main rotor blades. Try http://www.fxaeromodels.com/blades.htm
MS-20395 395mm Carbon Blade for Concept EP $58.00 USD
There are shops in Hong Kong, a lot closer to you than the leads I have provided that should have EP items also.
Hope this helps.
