What is the minimum radius that this loco will operate on? My layout is LGB R3 minimum and I have had problems in the past with these locos derailing.
 
Page 8 of the manual says 8' diameter, but you have to use the optional coupler box


What this means is the loco will run 8' diameter, but you may have trouble keeping rolling stock coupled, normally too tight and the coupled car derails.

There's tips on the USAT 3 axle series locos that greatly affects their trackability:

So I carried out the pcb hard wiring to provide power to the lights etc, programmed my revo sound receiver, linking was successful.. However when I powered it up today, no lights on no internal cooling fan etc, but sound board has sound,, so my question is,, is there any revo transmitter settings that could have been corrupted and resulting in no power to K27 flicker board,, do you know Greg,?

Does not sound right.... so where did the instructions to add the jumper for power come from?

Give the link?

Also, is this battery or track power?

Can you post the link? Some of that information is flawed. I'd like to read the whole article.

Let's start a new thread please! This is a thread on a SD40, and the new topic should be "Bachmann K27 with Revo" or some-such.

I'll look for it.

Hi Greg I found the problem, a dry joint on the main + pad,, working fine now, so the mods I had referred to previously do indeed work.

Soldering is so much fun.

We had issues with Aristo, where the circuit boards had holes for wires, but the assembly people in China (Kader) just laid the wire on the board and put a dollop of solder on it.

Guess how many were "cold solder joints"?

Glad it is fixed...

Yeah, no schematic, I have not opened mine, but very similar to all USAT diesels.

The volume is settable to high, medium, low, from function keys: 7, 8, 9 respectively... sound on off is 1.

Dave Bodnar was Aristo's replacement "engineer" after me, who was after George Schreyer (a funny story that) and he has a lot of info on the Revolution:

I have a page on the 44 Tonner, but mostly about history, and the aftermarket Kadee mount (which looks great!)
