3d-aholic--Don't get hung up on HP numbers, they really do not mean much. (as stated before) Now if the manufacturers would give you torque/hp curves you would have something.

The 110 should spin about 100-300 better than the 100 from what I have seen and read. (both are good engines and you can't go wrong with either) Also the 110 is no longer manufactured, it has been replaced with the 115. The new 115 is "supposed" to turn about 100+ better than the 110, we will see. Not that it means anything, but my 110 will spin a mejz 28x10 at 6500 static on stock mufflers.

Silversurfer,,Was that comment about "beat it into the dirt" about the power of my 110 compared to your 105, or the fact that I did beat my plane into the dirt the last time we flew
