    • 2n2907 is what is typically used for pnp, 2n2222 for npn

      Thank you for helping me. What type of PNP transistor would I need? Also, I checked Reindeer Pass and RLD with no luck as to finding the cord. Is there any suitable alternative?



      John not sure what you looked up but RLD does have the cord here is the link

    • Interesting, I see the mods to allow this to work from track voltage, a bit more complex, but makes sense, you need the Phoenix to power the chuff circuitry and add a couple of transistors to do so, and don't know why they don't give an alternative to wiring the smoke unit instead of just telling you to leave it off permanently. A bit more rewiring would fix that.

      Nice complete instructions from Phoenix though.

      I entered dcc in the search and this board showed up ... does say dcc and 5 amp.

    • I'll call in next week, clearly something being planned.

    • I am well aware of what the current Train Engineer Revolution is and what it does. I have been using it since it became available from Aristocraft. I agree that is not DCC.

      Several days ago the folks at Precision RC revised the “Products” tab. There are now three sub categories under the “Product” tab. You will find “Revolution”, “Revolution DCC” and “Accessories”.

      A few days ago there were a transmitter and a receiver shown under the “Revolution DCC” tab. There were some specifications described – such as CV’s and DCC operation.

      On Thursday, 11/23, these were gone. If you select “Revolution DCC” it says “There no products matching the selection”.

      The “Revolution DCC” tab remains. Here is the link to the “Revolution DCC” tab. Revolution DCC

      I now ask again if anyone knows anything about ‘Revolution DCC’. Maybe some of you that appear to have much closer ties to Train Engineer Revolution can extract some information.

    • Tom,


      Revolution is NOT DCC.  Revolution is a proprietary control system originally developed and marketed by Aristo Craft under the Crest brand. When Aristo Craft folded up their tent, the owner tried to continue the Crest product line and soon closed that as well. As with most things these days the actual engineering and manufacturing was done by far east company, in this case in Korea. Today the new product under the 'Revolution' banner is manufactured and now supported by the same folks that did the engineering and manufacturing in the first place. Although I chose another system to go with for reason that were relevant at the time, today I would seriously consider the Revolution system for locomotive control. It works well with constant DC track power and either a track side controller (like our standard old time power packs) or an on board controller (mounted in the locomotive). Revolution will also work well with a battery power system, eliminating the wiring issues associated with track power.


      I am in no way putting DCC down, it is a very viable control system, one I know very little about. I hope this will put some clarity in the Revolution story.

    • Just enough to tell you it's not DCC, it's a stand alone system. Fewer bells and whistles and cheaper, I think. Spun off from Crest electronics which was affiliated with Aristocraft. has been picked up by it's developer and is now a healthy product and the sounds are improving.

    • I'm not an expert. My opinion is based on those of experts that have posted here in the past and my experience. Tenergy cells are made in China whereas Panasonic, Sanyo and others are made in Japan. It was the opinion of experts (people in the business of making or selling packs) that the Japanese cells are superior quality. The do cost a few dollars more per cell.


      I had good luck with the Thenergy packs for quite a few years, and in my post above I admit that failures have been mostly my own fault. I recently bought a high quality pack from Don Sweet at RCS New England that I believe is made with Japanese cells and a unique protection board the maker claims to be superior. My experience with this pack is that the self-discharge rate is very low compared to the Tenergy packs I have.  This isn't a concern if you charge your packs regularly, which I have failed to do in the past leading to early failure from over-discharge


      I am not saying the Tenergy pack you own is junk. Properly cared for it will serve you well. I still have Tenergy cells built in to multiple locos and they are frequently charged and perform well.

    • I use primarily the Tenergy packs from All-Battery for my large scale stuff, unless there's a specific form factor I need that I can only get elsewhere. The only "questionable" Tenergy packs I've used were the ones I got 3 or so years ago from All Electronics for $15 each. There was a lot of discussion here about those packs, whether they were "factory seconds" or something like that. But--hey--at $15, if they lasted two or three years, I was still ahead of the curve.

    • My understanding is that the aforementioned Tenergy battery is of good quality. So you're saying they're not? Please clarify (with a link) which pack uses quality cells. Thanks.

    • Cheap meaning not quality cells, not necessarily low cost. You can buy that same pack for a few dollars less from the source, All-Battery.Com (Tenergy's site).  I buy the smaller 2200AH packs - they are fine for my needs and cost a lot less. The same pack using high quality cells will only run you about $75.

      I wish my battery life experience was as good as Kevin's.  I will, however, admit fault.  At one time I had too many cheap (Tenergy) packs in my rotation and they sat idle for too long. Cheap packs tend to have a higher self-discharge rate and the protection circuit only protects the pack from over discharge when being used, not from self discharge. The result is that if you don't maintain the cheap packs while in storage they will self-discharge to uselessness.  I've also been guilty of abuse by drawing too much current, beyond the packs comfortable discharge rate, but within the protection circuits current range. This causes the pack to get hot and when LiIon gets hot it breaks down.


      I recently decided to spend the extra dollars and buy a quality pack from Don Sweet last summer for my C-19. It is early yet, but so far it has performed flawlessly and holds a good charge for a long time.  I was surprised to find when I put my Shay back on the track after being boxed up since TrainOps in early August that the Tenegy batteries inside were still at nearly full charge.  The batteries in the Shay have been treated much better than some of my old packs.


      I now use a programmable charger as well which I expect will help as it does not depend on the protection circuit to limit the charge time/current like the cheap chargers do.







      "Cheap Tenergy batteries"? This one was recommended to me by a couple of BAGRS club members to slide into my USAT F-3AB units and GP-9. It sure ain't cheap!

      True, but you don't want to get the twine guys in the same room with the fishing line guys. That's just asking for trouble.  And the neon paracord guys are just insufferable elitists.

    • Yeah, but you leave all your other Li-Ion stuff charging "alone", right? Have you ever seen anyone put their cell phone, laptop, bluetooth headset, electric shaver, cordless phone in a ceramic jar or on a large ceramic surface when charging?


      Those can (and have) go bad...  so, I do indeed realize that our lithium batteries in our own installs might be somewhat more susceptible to failures, perhaps from either the installation, or perhaps lack of protective electronics for over/under charge/discharge, but lithium batteries are a reality everywhere now.
