i have been using my new t maxx and got it really muddy



so i took all apart cleaned and oiled everthying that needed it but and i have put it back together

it looks fine but there is a big problem, when i push the front wheels forwards the rear wheels goe backwards and vice versa. so i will not start the engine because the wheels are fighting each other

also the slipper clutch pads have been changed and the slipper clutch does not not move when the wheels spin.



where have i gone wrong!
