Peteski, I hope to have some progress to report on the Flying Yankee soon.
Brian, for the Silver Charger I'm thinking of a custom chassis to take the motor and one truck from a LifeLike E7, with a Kato prewar streamlined truck on the rear. There are a couple of crude photos on my website now, which I hope to replace with better ones once I have a little time to set up a proper environment for the lighting.
But now that Kato is running their E5, it might be easier to source a motor and u-joint and power truck from them, at least for the time being. Maybe I'll need to do two chassis...
For the EA/EB, I am envisioning a similar situation--a custom chassis to take the running gear from an older plastic-frame LifeLike FA, which has the right trucks.
