I bought into the Hornby HMDCC dream and bought a iPad Air as it said supported BUT to my disappointment after downloading and installing realised it was not supposed!!!
What a pile of rubbish. Hornby just rushing product out as usual and customers doing the testing and R&D for free!!!!!
Absolutely Delighted
I have returned to model railways after a 30+ year break, and DCC was completely new to me. This App and the system underlying it has made my assimilation of this new tech very easy. The App’s interface is intuitive and very easy to use and the potential for the whole bluetooth control this App offers, is huge.
I’m absolutely delighted with how straightforward everything is and have now installed eight decoders into my loco collection, all running beautifully.
Very well done Hornby…….a superb effort ! I recommend this App, highly.
Great support
I mistaking used the HM DC rather than the HM DCC app and managed to corrupt the decoder. However I received fantastic support from George at Hornby who reset the decoder. It now works perfectly and the sound and loco control is excellent.
iPad train control
I’ve been running trains using wireless DCC control for years, but the introduction of Bluetooth has huge potential. The setup was very easy and the control screen works very well. Everything you need is easy to find on the App. I am delighted with the system in general.
I now have a battery powered OO train which can run round the garden, in all weathers and with dirty track.
Great start, huge potential…
This is def v1 software, but that being said it’s actually very capable for v1. The sound effects are excellent, and assuming they have the sound profile you want this is the best sound-enabled system on the market. And frankly for most of us, even if it’s not the actually exact sound of Obscure Loco X, you can easily find something close enough for ordinary folk.
Would love to see simple routines brought in, and waiting too for a TT track builder. But well done. So far, so good.
Decoders are good but the software is hot garbage!
Why on earth do decoders require registering to your device? I’ve bricked two already due to a bug in the registration process. It’s a completely unnecessary requirement, ruining what could have been a great product. I will be discouraging this product until this is sorted!
First DCC set
This is amazing, works perfectly and really easy to operate via my iPad. Saves all the wires. I also fitted the capacitor for extra stay alive power and purchased the 15v 4amp power pack for the track. No issues works perfect.
Now let the big boys and their toys have fun.
Sort of new to this and model railways but comparing this to my old set track train set I had many moons ago….it’s like Iv stepped into a different dimension. My new pass time is the great and exciting Hornby TT:120 scale and this app makes my learning curve much easier and more appealing to me. Absolutely fantastic Hornby.
iPhone v iPad control
Seems to work very well, only installed in one loco. Added sound an I’m impressed. However, I might have missed something but I have setup the loco on my iPhone but cannot see anything on my iPad. Both running updated iOS. Have looked out and back in on both but no transfer between the two. Since I have to have a Hornby account surely the data should follow the devices!
Compatibility
Although the app states it will work with various iOS revisions some versions on some devices are still in work as prominently stated by Hornby on their web pages.
All in all the app is intuitive and simple to use. For those who are unable to master on screen prompts there are a complete series of step by step how-to guides also on the Hornby web site.
In the event even that help is insufficient the Hornby forum has a separate section for HM DCC.
