I have had good luck with Turnigy motors from Hobby City. I couldn't begin to tell you which one you need, but they are great motors for the price.

If you go to the Hobby City website, under each motor there is a comment section where people rate them, list off their setups, and post a lot of test data. You can probably find either the same plane as yours, or something close, and copy somebody else's setup.

This is just an example - I do not think that this motor will fit your plane:
