at Carrefour City Centre, TOYS SECTION... i saw similar ones.. but not exactly of the same specification as to your given site... but perhaps it would still fly... just try...

another clue... visit sometimes open beach at Sealine, u may find some westerners playing such hobby... biwinged-plane born with petrol driven engine from a remote hand control... think bit better than that from the site...
