110 sounds a little crazy. On the 81a I use a 14X7 prop and ground clearance is OK but not a lot to spare. The carb is quit close to the firewall and you may have a problem there. It flys great with this engine, the biggest downside is on the ground. With a very slow tick over, on the tarmac she's still moving, on the grass (as long as it's short) it's much better.
Hope all goes well.
