Rapido N Gauge Class 44 Peak

Kit: MS581G; SugarCurve7

Lovely little Peak from Rapido, excellent smooth/silent runner, so let's see what we can do to get good sound fitted...

The model comes with a factory-fit SugarCube style speaker, so a simple approach would be an MS581, just plug it in and off you go!

However, we found the sound quiet and a bit rattly with the factory speake, so we look at replacing this. The PCB has to be removed to get access to the screws that hold the speaker box in.

Our first approach is to ping out the factory speaker and fit one of our StickyGasket 15x11mm components instead. This does prove to be noticeably louder, but the seal is not great so we hear some crackles.

So the approach we plump for is to use a SugarCurve7 fixed in place so carefeully so it contats in the correct place, held in with Kapton tape. This sounds so much better.

For stay-alive, we add a pair of mini GoldCaps (in series), which can be directly connected to appropriate pads on the MS581/MS581G. Wrap in Kapton and secure them above the motor area where there is plenty of space.

Transformed! A great model now an amazing model!
