Dapol's quirky little Sentinel presents something a little different. Comes with a simple 21pin DCC socket, so the sound
decoder is a piece of cake. Various options for speaker, but we decide to go relatively unobtrusive and tuck a single IceCube
inside the vertical boiler area, hidden out of sight.
The model comes pre-wired for a speaker in that location, though the intention is for a round speaker. A larger speaker would
also have been feasible on the cab floor.
The vertical boiler and panel unscrew, and we very carefully prise off the barrel from the base. It isn't intended for you to
do this, and you'll inevitably have some repair to do on the detail parts afterwards, but this course of action allows us to
get the biggers IceCube in that space that we can.
With that done, and the barrel lightly glued back onto the base, we can replace the Sentinel's body and try it out with sound.
Pretty good, but with such a short wheel base, and being light (for an O gauge model), we decide to add stay-alive in the form
of a LinkLink plus 17000uF SuperCap. This all fits fairly neatly under the cover with the decoder.
Just to add a bit of fun, we also include a bi-colour working lamp on each end. Some careful soldering required to the feet of
the 21pin adapter to make this possible, and a bit of remapping of AUX outputs on the sound projects, but looks great once
Add some ModelU figures, hand painted and weathered, and this completes a neat little installation!
