Old world fruit bats cannot echolocate, and athough bats do not usually have claws on all five fingers, they usually have claws on 2 or 3.
Also, it had fully developped wings and could clearly fly.
Just to clarify some facts that I felt weren't toallyl accurate/transparent in your post, might want to check your sources on all this. (I'm not an expert on bats, mine was the wikipedia page on Onychonycteris)
With all this in perspective, I don't get the feeling it is a very good example of a transitional fossil, since it has no transitional characteristics outisde of the five-to-two clawe fingers, which a creationist would argue is a 'downhill' transition.
Although I could be wrong, I would pretty much bet that Onychonycteris would be the ancestor of old world fruit bats.
EDIT: I'm not jumping into this conversation, but I just felt that I could do my part to help the poor fellow who doesn't seem to know in what an endless and long conversation he is entering. I figure that if his rebutters would at least use accurate info, it would help also.
