Fitting HM7000 to Hornby Class 71 R

[Wayne-in-Oz]

Ok, I am trying to consolidate the Class 71 discussion from the "Confirmed list of Hornby locos working and not working with HM7000 DCC Bluetooth" thread so that I can then delete my posts in that thread to try and clean it up a bit as requested by Fishmanoz.

So, below is the post by rpjallan

Hi Wayne-in-Oz

You are right in that I fitted the main bluetooth decoder and speaker under the PC board on the R3569 BR Class 71 Blue. I just disassembled my loco for you and created a small video showing it running with the model top off so you can see it does fit and work with the HM7000 fitted.

I have also created a video with the model loco resembled. I have also taken a few pictures as well for you. I will load them up to We Transfer and give a link but I think under the rules of the forum I need a moderator to approve the video in a we transfer link before I post it. Please can 96RAF or RogerB please give guidance for helping me share my video with Wayne.

Cheers

Mark

Did this link ever get posted? If so, I can't find it. I'd like to have a look at the video as I have one of these locos & have been putting off trying to install a decoder in it.

Never saw the video but its reasonably straightforward to install. The hardest bit is to run the cable for the speaker in the 71. If you turn it over, next to the two switches, there is a purpose made place to fit the sugarcube speaker in the second smallest (from memory) enclosure. Dont be concerned it wont be loud enough.... I have mine turned down to 25. But to run the wire, you basically have to disassemble the PCB then Motor etc to get it routed. Fiddly getting the two drive shafts back in during reassembly but thats the most painful bit.

Now, I decided that it was a bit tight sliding the decoder under the PCB above the motor and also the motor might get warm so I decided to remove the fake Booster molding and put a put a piece of black cardboard over the window just taped on. This allows both the decoder AND the Stay alive capacitor pack to fit.

Mine runs a treat and I dont miss the fake Booster as I read a review that showed pictures of the real 71 and it is actually mounted very low in the engine compartment so it cannot be seen through that window.... well not at that angle. Also, the engine compartment light would have to turned on as well otherwise its a black looking at the window so I feel mine is now more accurate :)

Thanks for the info. Much appreciated. I had already read about removing the "booster". I'm not even really sure yet if I'll put sound in it being that it's an electric loco.

Just another question as you seem quite knowledgeable about this loco. Is it fitted with cab lights? I assume it is but there doesn't seem any way to turn them on with DC.

Here is a link to a video of mine pulling a rake of Pullmans on a friend's layout, if you're interested:

Hi Richard,

Loved the video, your friend has a lovely large layout. Mine is small but happy with it.

Anyway, YES, my Hornby 71 has Cab Lights. Also Headcode and Head/tail lights which are all independently combined and controlled on the HM7000 App (Function 0).

Like you, I didn't know it had Cab Lights until I put the HM7000 in to replace a standard Decoder I put in (I think a DCC Concepts one). Mind you I didn't try the CV for that decoder to turn on extra lights. So, check your Decoders manual and try the different lighting CV's/functions.

Oh, the Cab Light is Function 21 on the App (third page, first light button).

Here's a quick video

Thanks for the video. Much appreciated. I wouldn't mind fitting a crew when I do the decoder.

Where are you located? I'm in Adelaide.
