The driving while flipped over is going to be a challenge for any hobby grade vehicle .Grass is always tough on a remote control truck or car. I like the idea of using a gym you could use a 4wd touring car it would give you plenty of traction and you could simulate a fighting fish. Outside on a grass a 4wd truck might be the ticket. I don't know what your budget is but along with the cars your going to need a good charger and batteries. This could get a little pricey. I like the idea though.
A 4wd buggy might be a good choice.
Thumb up for 4WD. xD nice pick.
