Well the 110 over the 100 should have 5% more power, so that may contribute to the 200 RPM.
However, the bigger engine being lighter is a good accomplishment.

One question that is valid ... would you need more nose weight to compensate.
If one takes the time to plan ahead, it could be a nice weight savings.

I have a DA-50 and it runs fine. Time will tell if it is reliable.

All the major manufactures seem to have good engines. Picking depends on personal preferences in some cases ( rear induction, carbs out the side of cowlings, reed vs rotary, mag vs electronic ignition, etc.). Some things are important to each individual, some are not.

But dependability is needed by all !!!!
