    I purchased 4 items from this seller during the same auction. All items were just as described in the listing: new in original packaging. Sales price was excellent. They were carefully wrapped and shipped promptly with a combined shipping rate. I am very pleased with these purchases and will continue to use this seller for future hobby purchases. AA++

    GO NITRO HOBBIES IS one of the best sellers to deal with on EBAY! GREAT COMMUNICATION, QUALITY PRODUCTS, NEW IN THE PACKAGING FROM manufacturer, and probably best price on EBAY for the ARRMA CENTER BRACE! Besides great communication, they have lightning fast shipping, and packages comes bulletproof! I always buy from GO NITRO HOBBIES for my TLR 8IGHT 4.0 T OR MY ARRMA TALION 6S BLX! IF YOU WANT THE BEST, DO BUSINESS WITH THE BEST! I HIGHLY RECOMMEND GO NITRO HOBBIES FOR ANY NEEDS YOU MAY HAVE!

    easy conversion

    This conversion assembly makes it almost a drop in conversion of older Athearn locomotives. I highly recommend this conversion package to anyone wanting to upgrade to DCC one of their older loved locomotives.

  • Genesis Motors in old Blue Box Trainmasters

    I actually installed, with a little improvisation, two of these motors in two old Athearn Blue Box FM Trainmasters using Genesis drive lines and worm gears, NWSL replacement wheels and NEC DCC decoders. They operate smoothly and the motors were well matched to each other so these units operate very well together.

  • Genesis Retro Motor

    Good quality silent motor I've come to expect in an Athearn Genesis motor. I installed it along with new drive shafts and worm gears in an old Athearn Blue Box loco. It toot a little work with a Dremel to make mods to fit the motor in but was worth it. I love the duribility of these old locos and the Genesis motor and driveline upgrade makes it a smooth runner.

  • Versatility supreme

    I have bought 4 of these to successfully convert 4 old Athearn Blue Box Trainmasters. Once they, and the other necessary couplers were installed, they ran beautifully. I suggest they can probably be used to convert any Athearn BB loco to DCC.
