Dave, your post reminded me I wanted to try that so just did. Put a MTH detector engine, and a TMCC Hudson all on the same track. No problem running them all at once. Too bad I only have a test track and could only run them a few feet.
The basic install is actually pretty simple. Add a AC to DC supply and you can have a running engine with sounds and lights in 20 minutes. Not much harder than installing a E unit. Its the add ons that take time. Not many in the DCC world use electro couplers and not sure many more have working smoke so the Blunami doesn’t provide that directly. Intermediate circuits have to be added to do that.
Where these shine is the sound selection. Legacy now has 5 whistles. This has 90. Plus choices on most all the other sounds, bell, coupler, dynamo, etc. The other place they excel is being able to add your own features to an engine and label them accordingly in the control panel.
It has Back EMF and runs fairly steady but you can see in the video that it sped up after uncoupling the train. Still low speed is fairly slow and steady.
I don’t expect this to replace ERR or PS3 kits until they disappear but if they do this is one way to keep them running and with all the features plus more than Legacy. Maybe a cottage industry will spring up to make those add ons for those that can’t design and fabricate their own.
