Hi Joe,
The EuroSport is very well suited to grass. I only ever fly mine off of grass (not a cricket pitch either) and haven't had a problem. Comp-ARF also now supply a heavy duty retract kit which is well suited to grass operation. The last 3 guys who ordered aEuroSport through me opted for these retracts as they all fly from grass too. As for slow landing approaches, with the large delta wing you can find yourself landing at a high angle attack with 50% power and at very slow speeds!
The L39 is great off grass too but is obviously a lot smaller and lighter.
Rgds,
Mark
PS If your "3D_Man" is anything to go by, it has to be the EuroSport
