Yes, John, I did. Considering I bought one of each at York, I know they work very well with ERR upgrades and are very easy to install. Of course this is if I went with the Cruise commander.
If I went with the Legacy motor driver, I might have to add something else to control it instead. Of course using the Chuff Generator and Super Chuffer would be much easier and fit into the rather tight confines of the American Hudson's boiler, minus the open cab, if the two could cooperate with each other.
The plastic coal load on the 18005's tender would be easy to create a Command antenna. Do Legacy locomotives have an antenna despite the 2.4 GHz frequency?
Again, IF (and keyword IF) the basic sounds (chuff, bell, whistle and maybe CrewTalk) of the 6.0 board can be controlled with the ERR commander, that's all I need. And again, I will not be using a wireless tether.
Oh yeah, and in a future plan to mate the 18056 Hudson with the CC2 PT tender, a simple swap of sound boards from 5 to 6.0 would be another beast of a problem altogether as well?
