Voltage: For live steam systems, we recommend a 4.8V battery pack, which is four cells.
Cell Configuration: We can create custom battery packs of any configuration for you, depending on the size and shape of your loco.
All the battery packs we supply come fitted with a fast blow fuse as standard.
Fosworks supplies a choice of three standard switch looms, each including a switch and a charging socket. The only difference is the type of switch used in the loom. The types available are a mini toggle switch (PNP-110), a sub mini toggle switch (PNP-120), and a slide switch (PNP-100). Choose the type of switch you prefer to use.
We strongly recommend that you use a switch loom in your loco, as this makes it much easier to charge the battery without causing undue wear and tear and unreliability of the battery connector.
All the servos we sell are high quality. Generally, the smaller the servo that you want, the more expensive it will be, but the easier it will be to fit into your loco.
We have standardised on the HS-65HB (RCA-124), the HS-82MG (RCA-125), and the HS-311 (RCA-120). These cover nearly all of the installations we have carried out, and are all capable of operating regulator valves and reversers. The HS-65HB would normally not be used in Gauge 3.
For a loco with servos, such as live steam, the standard choice is one of our FRx23 range of receivers. The receivers come with either horizontal or vertical pins, depending on what kind of space constraints apply in your loco. The FRx23 H is longer, but the FRx23 V is taller once the connector plugs are connected. Both versions are also available with a long aerial (FRx23 H LA and FRx23 V LA), though this is usually only necessary if the receiver is going to be placed inside an enclosed metal box.
To go with your FRx23 receiver, you will need an OMNI Tx-3.0, Tx-3.1, or Tx-3.2 transmitter.
The OMNI Tx-3.0 can be used to control up to four servos. It features two full-travel knobs and three function buttons, as well as a power button. The knobs control one full-travel servo each. Function buttons one and two control the third servo, allowing it to switch between two end positions and one central position. The third function button controls the fourth servo, which moves one way when the button is pressed, and then returns the other way when the button is released. This final servo is useful for controlling features such as whistles.
The OMNI Tx-3.1 allows you to control live steam locos and battery-powered DC locos with the same transmitter (though not at the same time). The default position for servos one and two is in the centre.
The OMNI Tx-3.2 is a special transmitter suited for use with Brian Jones sound cards with the R-Cat option.
