On this web site you will find information about Ultrascale products. Ultrascale is the name under which a range of 4mm scale items for modelling British outline steam and diesel locomotives is produced. This range includes the most common locomotive and rolling stock wheels and conversion packs for proprietary, ready to run locomotives. Most of these items can be supplied for either 'OO' Fine scale, E.M. or 18.83 gauges. Also available is a range of worm and wheel gear sets and spur gears suitable for 2mm, 4mm and 7mm scales.
For a comprehensive and up to date list of products and prices, please visit our 'Products' section.
We are currently working on infrared sensors to detect the loco as it passes. These can then be used as either a built in shuttle system or a station stop option.
Also the control software has now been updated to include Direct and Main drive, along with Aceleration, Deceleration and Braking options. This latest version is currently under test with the new version 5 control hardware system.
This calculator is an iPhone app that can be used to calculate the Outside Diameter, Centre Distance and Ratio of spur gears and pinions.
Please note that this calculator should ONLY be used for spur gears and pinions, NOT for helical gears.
This calculator was initially developed for use with the spur gears and pinions available via the Ultrascale web site. However, it can be used for spur gears and pinions from other sources.
