Google his name and 13B. He has been flying a 13B and long Ez combo for a long time. He originally did a ducted fan for it! His trials for that config are an interesting read. He later converted to a PSRU and regular prop. He can probably give you a good recomendation. I don't remember if his PSRU is Tracys.

This is mainly a matter of "does it hit the ground when you rotate?"   This is best answered by the aircraft kit maker (although Burt probably won't give out any info anymore since he bailed on the homebuilt market).  Do your own measuring and decide on how much ground clearance you can live with.   Or make the landing gear longer until it fits the prop you want to use.
