Motor mount offset angle 0.50mm

Fine adjustment for anglewinder mounts: the 0.50 mm offset motor mount from Avant Slot

In the preparation of a competition slot car, the small details make a real difference on the stopwatch. The 0.50 mm offset angle motor mount (ref. AV20575b) from Avant Slot is a specific spare part for anglewinder setups in 1/32 scale, designed to fine-tune the alignment between the motor and the rear pinion with a controlled deviation of 0.50 mm.

Function and performance

The motor mount is the component that secures and orients the motor within the chassis, determining the angle and exact position of the drive shaft relative to the rear axle. In an anglewinder system, the motor is positioned at an angle to the rear axle, which directly affects the meshing between pinion and crown gear.

The 0.50 mm offset incorporated in this mount allows for compensation of play or dimensional differences arising from different combinations of pinions, crown gears, or chassis, thus achieving a more precise and quieter gear mesh. A well-adjusted gear mesh reduces power loss due to friction and improves acceleration response.

Compatibility and installation

This mount is an official spare part from Avant Slot for its 1/32 scale models with anglewinder configuration. If you are preparing or repairing an Avant Slot chassis of this scale and motorisation, this component ensures direct compatibility with the brand's original elements.

• Scale: 1/32
• Motorisation system: Anglewinder
• Offset: 0.50 mm
• Brand: Avant Slot
• Reference: AV20575b

Installation and preparation

When installing this mount, it is essential to verify in advance that the selected offset is suitable for the combination of pinion and crown gear you have installed. An incorrect offset can lead to a gear mesh that is too tight —resulting in increased temperature and wear— or excessively loose, causing a loss of efficiency in the transmission.

We recommend checking the backlash after installation: it should be minimal but perceptible when turning the crown gear by hand with the motor fixed. If the assembly turns with resistance or makes noise, try a different offset before finalising the adjustment.

Common mistakes

• Assuming that the same offset works for any combination of pinion and crown gear: each combination may require a different value.
• Tightening the mount without verifying the final gear mesh: once secured tightly, any correction requires disassembly.
• Ignoring the wear of the original mount before replacing it: a worn mount affects the gear mesh even if the offset is correct.

Frequently asked questions

What is the offset in an anglewinder motor mount?

The offset is the lateral displacement —in this case, 0.50 mm— that the mount introduces in the motor's position relative to the rear axle. It serves to fine-tune the engagement point between the motor pinion and the crown gear, adapting to different combinations of tooth profiles and diameters.

How do I know if I need a 0.50 mm offset or a different one?

It depends on the combination of pinion, crown gear, and chassis you are using. The most practical approach is to test the mount and check the gear mesh: if with 0.50 mm the mesh is well adjusted —without excessive tightness or noticeable play— it is the right one. Avant Slot offers different offset values so you can find the exact adjustment.

Is this mount compatible with chassis from other brands?

It is a spare part designed for Avant Slot's 1/32 models with anglewinder motorisation. Compatibility with chassis from other brands will depend on whether the mounting dimensions match. If in doubt, consult the specifications of the receiving chassis before installation.

What is the difference between anglewinder, sidewinder, and inline?

In a sidewinder setup, the motor is parallel to the rear axle (transverse). In an inline setup, the motor is in line with the rear axle, lowering the centre of gravity. In an anglewinder setup, the motor is positioned at an angle to the rear axle, combining advantages of both systems and being very common in 1/32 competition cars.

Can I use this mount for official club competition?

Yes, as long as your category's regulations allow the use of preparation components and original brand spare parts. Being an official part from Avant Slot, it does not introduce unapproved modifications by itself.

The Avant Slot AV20575b anglewinder motor mount with 0.50 mm offset is an essential spare part for 1/32 slot car enthusiasts focused on precise gear mesh tuning. Designed for anglewinder setups, this motor pod allows fine adjustment of pinion-to-crown alignment, reducing friction and improving power transfer efficiency. A must-have component for club racers and hobbyists building or restoring Avant Slot 1/32 anglewinder chassis.
