As speed said, it is usually more of a CG thing then the prop. Still, the only way to tell what prop you like is by testing. And when testing don't forget the three blade props. The 14 is not too small of a prop but it may be too small for that combo. I don't often use a three blade but they are like putting on the breaks when you cut power. I also have the three way switch set up like JD mentioned. Up is a high idle I use to start and while in the air, center is very low for while in the pits or taxi/landing and down is kill. Works for me.
