On mine i used an OS1.60FX and an APC 18X6W. Plenty of prop clearance. The plane is a little heavy but solid. Be sure to check you stab incidence as it will probably be off from side to side and off with the thrust line. It is one of thoes planes that seems to always be hunting for a straight line. I used mine for learning inverted stuff low to the ground because it is cheap compared to others out there and a mishap learning new things would not break the bank.
