I am building the tug Wattle using the build article in model boats magazine, but I have come upon a problem as this is my first scratch build I am lost with the radio installing and am hoping someone out there can help me maybe with a wiring diagram as I have to install a smoke unit a sound module lighting etc.
Hi Michael If you look at this **LINK** there are a number of circuits. Although they refer to Action units specifically, the basics are the same for most R/C components.
Some Smoke and sound units are linked to the motor control, although some modelers prefer to have separate control.it is a matter of taste
Also have a look at Dave Milbourn's very helpful article on Model Boat Electrics/Electronics here: **LINK** which should answer many of your questions.
If you are not clear about anything then just ask and someone will help.
