If I had to do it over agian and bought the airplane before I bought my ZDZ 40 I would have bought an OS 1.60FX for it. Only because it would have been easier to mount. I think it would be a great motor for this airplane. I saw a guy with the OS 1.60FX in a 1/4 H9 Cap 232 and pulls it with authority. FOR THE PRICE You can't beat it compared to a 4Stroke the same size...... Good Luck....Just my 2c.
