I have the same plane. I ended up putting a moki 1.50 on it... What a great motor. Fits the bill well....... lighter than the 1.8 and lots of power

here is a link to the moki 1.50 www.justengines.unseen.org it has a smaller case than the 1.8 moki. the 1.8 and the 2.10 are the same size motor case.
