Gregg,
There are definitely a few other threads on this subject, however I like my DCS HHRC, in fact I had it upgraded to fully rechargeable, love my Legacy HHRC also, no need for a phone APP, to run my Trains. However I am almost 70 years old now, and we need young guys & gals to keep our hobby alive, if they like the APP's more power to them. Don't like the fact that MTH is not going to build HHRC units either. I like modern technology but I am hands on when it comes to operating my remote control O Gauge Trains.
