That was 2003. Gone pretty quiet about it since. Original (stated) plan was to supply it OEM only for a certified aircraft customer, but since then no news I have heard.
Incidentally our group fly our planes on Rotax 912 and 914 and several of us have had problems leading us seriously to doubt their half decent reputation, including brand new engine which failed immediately and which they seem not to want to replace. Personally I would prefer to fly on something else.
