Kerbal Space Program

a rover weel is only working if the orientation of the weel is faceing downwards.
if a weel is facing another direction say 45 degrees from the surface(this indicates a rotation along the rotational axis of the weel) the weels can rotate freely and get no traction.
Not sure if this is bug or intentional.
to me it sounds resonable that the weels schould work as long as the suspension is used in the right direction.

i have so far tested this with rovemax model xl3 and TR-2l ruggarised veicular weel
