I have just installed the new Aristo Revolution in my K27 and it could not be easier. Just plug it in, link the transmitter and away you go. Less than 10 minutes.

I am also trying to install the Pheonix PB9, so far I have the bell and whistle controlled by separate triggers from the transmitter. Where I am having trouble is getting the chuff signals to work when the loco is moving. All the standing sounds work fine.

Has anybody done this, and if so can you give me some pointers?
I have been through the PB9 manual but it is based on using the dummy board that comes in the loco. I would like to use the chuff sensors that are on the unit if that is possible. I may eventually figure this out but thought maybe someone more electronics savvy than me might have already figured it out.
Thanks in advance for the help.

Thank-you for all the good information. Now I can enjoy my trains without worrying. I love my K27.

I have noticed that on my K27 if it is pushed with the power off that the drivers roll. As it has a worm on the motor shaft to the gearbox this does not seem right to me. My consolidation drivers do not move when it is pushed. Has anyone else  noticed this. Is this normal for this engine or is it an indication of a problem.
The locomotive seems to run normally and has no problem pulling 15 cars on a 2 percent grade.
