Five Shunter Challenge Pt3.2: Comprehending Compensation

Last time I discussed the difference between compensated and rigid chassis’ and my plans to build these five kits with compensation. As with all things in life, there are a number of different ways to fit a compensation system and the five shunters being built require quite different approaches. Today we will look at the compensation system fitted to the RT Models Sentinel.

The RT Models kit and instruction sheet are intuitive and explain the compensation system very well. The side frames include an elongated hole for the non-driving axle bearings to pop into, which allows the non-driving axle to rock up and down.

A pivot for the non-driving axle is created using a v-shaped etch that makes light contact with the centre of the axle. The pivot allows the non-driving axle to deal with cambers and uneven track.
