I would imagine you will find landing on pavement MUCH easier.

In Realflight I found I needed to increase the wheel rolling resistance to about 200% to emulate the tendancy of warbirds and other scale aircraft to nose over ( e.g. Gee Bee's ).

Grass introduces a lot of drag low on the plane, around the C.G.

Couple that with the higher wing loading requiring faster landing speeds, and you have a nice recipy for difficult landings, ground loops, wing drops, etc.

Land the same plane on pavement or asphalt and that drag is eliminated, so landings are far easier.
