It appears an OS 91 FS will fit entirely inside the cowl. Any thoughts on whether the 91 would fly this 12 lb airplane in a scale manner?
If you do the math, you will see that this model has nearly 1400 square inches of wing. It does not take much power to fly one at 12 lbs with that much wing area.
