Hi Nicolas
Although I couldnt find the web site for your plane to look at the specs, I'm also building a 330s and have put a O.S. .91 supass II in it.. While I havent flown it yet, others I've talked to with similar planes and engines all tell me that it has plenty of power to do most anything you'd want..
See the following forum for pics and build info.. Some/all may apply to your plane as well
