a 50k motor in a plastic chassis, no magnets and suitably brace, geared around the 5-1 mark is great fun on a home track. it certainly makes you better on the trigger. i also use metal chassis cars on my home track, with way way faster motors , one motor is a hard clicking cobolt motor in a lazer cut stainless chassis geared at 6-1 its controllable if yuo,ve got very fast reactions. i like to play and not be resticted in anyway, in fact one of my favorite cars to drive is a ninco 1966 gto, standard motor, just lowered and braced. you can get the back out and powerslide all the way round my big radius bends 5or4 radius. there 63in outside to outside. john
