The motor failed on this previous RP install. Ordered a new motor/flywheels from Lee at Bowser. Droppped it in, followed by an LM-3S, TCS KA3 keep-alive and Miniatronics 3MM LED headlight. I fashioned a mounting platform from .040 styrene to replace the Kato "board' and added beaders copper tape at each end, for soldering points. The long KA fit crosswise because I had milled off some of the chassis at the rear, originally to fit a battery for deadrail. Pro tip: Arrange your components BEFORE you start, I could have fit a KA4 in the cab. I used a Dremel to thin the inside of the fan assembly, to clear the LM. On my next F unit I'll cut down the screw towers on the engine mounting brackets to lower the component board, or -- HORRORS! -- remove the LM'S casing. Speaker yet to come, likely secured to the shell.
