I have owned my Roundhouse Criccieth Castle for 3 years now, it’s a lovely loco and the first one that I bought when the garden railway bug bit me.
But there have always been 6 little niggling things that I've never liked about it, so now, I decided, is the time to address these problems.
First. The Radio Control:-
Mine was supplied with an ACOMS 2 channel 2.4GHz controller of the type used for model cars, with a wheel for steering and a trigger for speed and direction. Roundhouse had wired up the R/C in such a way that the steering wheel gave speed with forward / reverse whilst pulling on the throttle trigger sounded the horn.
I have never liked this arrangement as I find it cumbersome to use, also I've found that the ACMOS R/C is very limited in it's range so I decided to change it for a Planet 5 system with the miniature R4Ms receiver, this fits neatly into the same position as the ACMOS receiver underneath the loco.
Second. The Driving Lights:-
I need to change the yellow LED front and rear driving lights for bright white LEDs as I could never see the point of them being yellow in the first place.
If they're driving lights then surly they need to be as bright as possible. This turned out to be a nice straightforward job to do as it was simply a case of unsoldering the 4 old LEDs from their mounting strips and soldering in the new ones.
