Morning 

Graham  -  One more to add to your list...SCX  Citroen 2CV,  surprisingly it is a Raid type car, 4x4 plus drop arm guide,  and as Marcury says, so much fun.

Regards Magnets. 

Whilst going over obstacles they do very little. 

Between obstacles,  or on longer sections which link sections of Off Road Track, they can make a big difference.  Especially if you are linking Ninco Off Road with standard Ninco track.  

So a class for Magnatraction,  and a class without is a good suggestion, especially first time around.
