Hornby LMS 4F with big sound and stay-alive

Kit: MX645; IceCube28X18X10-2W; SuperCap17000uF

It would have been quite easy to put an MX645R with a smaller speaker (such as IceCube18X13X09-1W), but we wanted to see how much we could cram into this tender!

We retain the 8pin socket, laying the MX645R flat pointing rearwards.

SuperCap for stay-alive sits on top of the decoder, and we create enough height for a massive 10mm high dual IceCube speaker - sounds awesome!
