@@minorityreport8718 DC FIELD conversion, AC conversion to DC, Digital Reverse, digital sound, chuff sound trigger synced to drive wheel, fan driven smoke on a chassis adapted to Puff & Chuff than never has Smoke. Digital smoke control and Puff synchronized to drive gear and chuff sound. Providing idle smoke when engine is powered up with no motor motion. As at a station or siding. Providing a strong Fan Driven Puff of smoke with a fan motor brake action between Puff triggers. All of these test have been on going the last 3 or 4 days. I am finding assembly errors and part issues. The video is to share the status of producing three complete engines for 3 users that saw a prototype the 2014 last month and asked to have one like it built for them. More wanted the engine but I had to stop at three. I am retired and a Flyer Hobbyist. Once these three are done we will offer the parts and subassemblies to all those that want to DIY build their own version. I post on Cults and Gum Road so sell parts. The last bit to do on this engine is dial in the smoke controller and assembly the 6 wheel trucks with. All Wheel Pick Up. Dennis
