Example 1: Hornby OO RailRoad Flying Scotsman with MS Sound and Stay-Alive (small decoder)

Kit: MS480R/481; IceCube18X13X09; STACO3B stay-alive kit

A revisit of Hornby's entry-level Flying Scotsman from their RailRoad range, we want MS Sound, with a decent speaker and stay-alive, so a little milling is required to flatten the chassis front-end, removing the 8pin DCC socket for hard-wiring.

The STACO3B stay-alive kit has a pair of 1F mini GoldCaps, connected in series, then wired throug the STACO PCB and onto the decoder's Common Positive and Ground connections. Some BlackTack and Kapton to hold it in position on the chassis.

At the front of the chassis, this is milled down flat and our 9mm single IceCube sits on some BlackTack. The MS480 goes in between - we may even have got away with this kit without removing the 8pin socket, but this is comfortable.

Example 2: RailRoad Flying Scotsman with big stay-alive

Kit: MS450R; RE Boomer 18x13x13; MGOBLOCK

This time, we want a bigger speaker and big stay-alive, so there is some modification to make to the chassis to get these in...
