I have previously published a couple of ways to go about installing the above equipment in the excellent Bachmann K-27. Having now installed battery R/C and sound in 5 or 6 locos I settled on the following method. I have discovered that, whilst the range with a simple antenna wire strung around the edge of the coal load is pretty good, a big improvement was made to the overall range by removing all the wiring and track pick ups from the tender. This is to reduce the amount of radiated Radio Frequency Interference (RFI) that is transmitted from the motor down into the rails and thence up into the tender. For this install I can recommend the following components. 1 x RCS # TX-24 24 function transmitter handpiece, 1 x RCS # PnP-3 MOTOR DRIVER (includes 1 x RX-8). 1 x RCS # BIK-U3 to access batteries for charging. 1 x RCS # Y-CABLE to place batteries in series. RCS also assumes you already have a method of charging the batteries via the # BIK-U3. The # BIK-U3 uses a 2.5mm DC jack as the interface. Positive (+) to the pin. We fitted Phoenix P5 + P5T for 6 x sound triggers. To access these functions you will also need: 1 x RCS # PLUS-3 1 x RCS # MOD-CABLE. The first step is to remove the tender shell to access the working area.  As explained above we removed all the track pick ups and wiring.  The clean tender chassis ready for installation.  The next step is mount the batteries in the rear of the tender shell a bit below the top. We used regular tilae and gutter silicone adhesive. Then suitably placed holes were drilled for the BIK-U3 (5/16" hole) & charging jack (1/4" hole) on the LH side and a 1/4" hole for the Phoenix volume control and a 5/16" hole for the Phoenix programming jack on the RH side.  The various components were siliconed to the tender floor.  After the previous step I decided to lower the Bachmann socket pcb to improve airflow around the controller cooling fins.  The various wires were hooked up. They are mostly plug in or screw terminal but a couple require splicing. The Orange chuff trigger wire on the PnP-3 was connected to the Orange trigger # 2 wire on the Phoenix P5. The trigger functions in the P5 + P5T need to be reassigned to enable easy interface with the RCS triggers. The next pic shows the wiring complete and ready to button up.  We have found the best place to mount the RCS RX-8 receiver component is in the middle of the plastic coal load. The antenna wire is then strung around the edge of the coal load and tacked in place with dabs of silicone adhesive.  We mounted a small black screw in the coal load to assist removal of the load so that the loco can be switched ON-OFF with the BIK-U3. Other sound systems can be used. We suggest you read the full RCS PnP-3 instructions as well as the above. http://www.rcs-rc.com/PDF/Battery_RC/RC … _TX_24.pdf Range is pretty good. At least 100' on our favourite test layout.

Thank you Tony. Most of my loco's have the antenna wire going down through the tender to track pick-ups on one side of the tender. Will this work with the K-27? (if and when I decide to get one?)  |

Hi Ken. You really need to talk to Dave about a wheel pick antenna. I do know he had to remove wiring and contacts from the loco to make it work. The way I do it above means you don't have to make any changes to the K-27 at all. Tony Walsham. RCS. E Mail rcs@rcs-rc.com |

Ken that is how I did mine a la TOC and it works fine but is because Tony did the real work!! Paul Bureaucracy is the art of getting nothing done .... very slowly! |

I know Don Sweet has done a conversion, but I'm not sure what all he did with the loco, ie: what he kept and what he discarded. When I get around to buying one and all the other necessary paraphenalia, I'll have to pick his brain before I start into it. |

What is the dimensions of the K-27? Especially width/height. I'm making a new bridge/tunnel, thought I might see if I can accomodate one, buddy of mine that runs on my layout is probably going to get one. Jerry Life is too short to take seriously. |

Hi Jerry, My K has a plow, its 6 1/4" wide 9" high and 38" long. I have been running it on aristo 8' dia oval of track, the engin has no trouble on the 8' curves it would look and run better on larger dia. I have 3hr run time on the engine no problems so far except the plugs from the engine to the tender came loose 4 or 5 times causing the engine to stop. I've been pulling 8 of the older b-man tankers, which look ok with the K imho. chuckger |

Thanks Chuck, that helps a LOT! Good thing I widened my bridge plans to 15". Jerry Life is too short to take seriously. |
