The Slot.it motors have three different shapes: traditional 'S' can, longer 'Boxer' type, or Slot.it's own 'Flat-6'.
'Inline' means the motor shaft is perpendicular to the rear axle.
An 'inline' motor can be either 'endbell inline' or 'can inline' if the pinion is either mounted near the plastic endbell, or on the other end of the motor, the metal can.
'Sidewinder' means that the motor runs parallel to the rear axle, i.e. transversely, and the pinion side discriminates between a 'endbell sidewinder' or a 'can sidewinder' like it does for inline motors.

The V12 motors features a double axle, which makes it a universal motor upgrade for cars of most makers, be it endbell or can inline or sidewinder of both types.
Further, a special 'RX' adapter is available, to upgrade cars with such a 'RX' motor to a V12 one.
The 'Boxer' type motors are an ideal upgrade for the bigger motors found on some slot cars. They can also be used as inline or 'anglewinder.

MX: no pinion version

MN: 9 tooth pinion mounted on the can side of the shaft, generally for
inline cars.

MS: 9 tooth pinion mounted on the endbell side of the shaft, generally for
inline cars.

MF: 11 tooth pinion mounted on the endbell side of the shaft, for most

MY: 11 teeth pinion mounted on the can side of the shaft, usually for sidewinder cars.

The FLAT-6 is a revolutionary new concept in slot car racing motors. It is a custom-built Slot.it motor designed both to be compatible with the existing Boxer/NC type motor pods, and to take advantage of a lower center of gravity when used in the special Slot.it motor pods, due to its 'slim' form, that also make it possible using it in anglewinder configuration under very low bodied GT racers like Slot.it's Audi R8C.

It comes with two magnet variants: standard, which is the strong magnet found in the V12/3 and Boxer/2, and Race 'R', with a custom built magnet to pack outstanding torque and braking in the motor's flat case.

The V12/3 is an all new motor family from Slot.it. All the existing motor components have been studied and, when necessary, upgraded to a better specification: case, endbell, magnets and balancing have been redesigned and improved. The result is superb torque, braking and power packaged in 'S' can motors that are also very easy to drive.

The V12 motor is an instant drop-in upgrade for most cars, thanks to its double shaft; several versions are available with the proper pinion mounted according to which car the upgrade is planned for, but any V12 motor can be changed into a different configuration just by changing pinion side and/or dimension: for example, a motor in a Scalextric configuration can be changed to an inline standard Slot.it Audi just by changing the pinion side.
