GO PACK!POWER CAP PK W/PL

Product Details
Do you have intermittent power problems with your layouts? Be it dirty track, pesky frogs or switches, GoPack! provides power to your locomotive even when your layout doesnt. Designed specifically for Paragon3TM locomotives, just plug GoPack! into the onboard port on the locomotive and enjoy continuous power, no matter what layout youre on. Each GoPack! provides between 2-6 seconds of uninterrupted power. Controllable for DCC: When used with a Paragon3 Revision H or above decoder, GoPack! has programmable CVs which allow your locomotive to be programmed on the program track even with GoPack! onboard. Dimensions: 30mm x 13mm x 9mm Frequently Asked Questions: Which models can accept a GoPack? HO Scale Paragon2 and Paragon3 (Revision E and lower Paragon3 decoder boards) can have the GoPack added via solder points. The solder points for the aforementioned decoders are under Technical Update Bulletins on our website. HO Scale Paragon3 models (Revision H and above Paragon3 decoder boards) have a socket to accept the wiring from a GoPack making it a PlugNPlay device with no soldering involved. There is no GoPack for N Scale models at this time. How do I know which decoder board revision is in my model? If your models box has the Accepts GoPack logo you have a Revision H board installed. If your model's box has this logo on it, GoPack! is plug and play. If you see the small socket directly next to the speaker output socket on the decoder you have a revision H board. If you look at the top of the decoder, you will see HO-300-X whatever is in the place of X is what your board revision is. Which models are GoPack Ready for plug and play operation? Models with the Accepts GoPack! logo have the Revision H or above board (which means it has the socket), and weve done the work to ensure there is enough space under the shell for it to fit under there. Will the GoPack! affect my ability to program on the program track? Programming on the mainline is no problem with the GoPack! However, if you'd like to read/write CV's on the program track in Paged Mode and/or Direct Mode you can either set CV221 to disable the GoPack! and then let the capacitors discharge (Revision H decoders and above only) or for a solder type installation you can either wire an On/Off switch in-line, or unplug the wiring from the GoPack! socket while programming. Can I send my revision E decoder in for a Revision H decoder? Yes, no problem and just a $50 S&H fee (or $65 International) its a one-for-one swap as long as the Revision E decoder is working when it arrives. If the board arrives defective, there is a $99 fee for an out-of-warranty replacement decoder in addition to the cost of the GoPack. Can I send my model in for you to add a GoPack for me? Yes, there is a flat rate $89 fee (in addition to the cost of the GoPack!) that covers all parts, labor, and shipping back to you for this service. You would be responsible for shipping the model to us. Can I use the GoPack on models that were not manufactured by BLI? Weve not tested for this, and would not guarantee any compatibility with other models. Which BLI models cannot work with the GoPack? Blueline, PCM, and QSI equipped models are not compatible with the GoPack only Paragon2 and Paragon3 HO Scale.

Questions, Answered Honestly.
A model kit comes unassembled on plastic sprues (the frames that hold the parts). You cut, glue, and paint the pieces yourself, it's a hands-on building experience that can take anywhere from a few hours to several evenings. A diecast car is a pre-built, pre-painted metal collectible ready for display straight out of the box. Both are scaled replicas, but kits are for builders who enjoy the process, and diecast is for collectors who want a finished showpiece.
Scale is the size ratio compared to the real vehicle:
1:12 — About 14". Museum-level detail, large display piece.
1:18 — About 10". Most popular collector scale. Often features opening doors, hood, and trunk.
1:24 / 1:25 — About 7". Most popular kit-building scale. Great balance of detail and size.
1:32 / 1:43 — About 4–5". Compact, ideal for larger collections.
1:64 — Hot Wheels size. Perfect for collecting by the dozens.
1:87 — Smallest. Typically used with model train layouts.
Choose based on your display space, detail preference, and whether you're building a collection or a single showcase piece.
Start with a snap-together kit, no glue or paint required. Revell and AMT both make great beginner kits in 1:25 scale, rated skill level 1 or 2. Pick a car you love, that motivation makes the build more enjoyable. Once you're comfortable, move to a cement-assembly kit with basic paint. We carry beginner kits starting under $20. Check our Beginner's Guide for step-by-step recommendations including your first tools, paints, and techniques.
It depends on the kit and your preference:
- Acrylic (water-based) — Beginner-friendly, easy cleanup, low odor. Tamiya and Vallejo are popular choices.
- Enamel — Smoother finish, longer drying time, requires mineral spirits. Testors is the classic choice for Revell kits.
- Lacquer — Dries fastest, hardest finish, requires good ventilation. Tamiya TS spray cans are lacquer-based.
Important: Don't mix paint types on the same surface without a primer coat between them. Every paint listing on our site clearly shows the type and compatible brands.
Skill levels help you choose the right kit:
Level 1 — Snap-together, no glue or paint needed. Great for kids and absolute beginners.
Level 2 — Simple glue assembly, minimal painting.
Level 3 (Intermediate) — Standard cement assembly with painting. Most kits fall here.
Level 4 & 5 (Advanced) — Complex builds with many parts and detailed painting. For experienced modelers.
We display the skill level on every kit listing, so you can make an informed choice.
