WHO Tech

Racemasters AFX have produced some excellent ‘How To’ videos to help beginners set up their HO track and cars and help with general maintenance and trouble-shooting.

The AFX Technical section is here.

Videos include:

How to assemble a track

How to clean a track

How to clean pick-up shoes

How to clean a rear axle

This is where to come when you’re ready to get out your tools and make those cars go faster.

With articles on simple tune-ups, modifications and complete car builds, you should find something to keep you busy.

All the tutorials are aimed at the WHO classes, unless stated.
