All good ideas. That transformer at 2.1 amps/40W (maybe) is definitely to small. One of my geeps E.I. 2349 NP with the same motor pulls 2.75 amps at 16V. Thats using a old KW. I also would exchange that old .027 track for .031. I know this was designated as 027, but it would sure run better on .O31. JMHO
