New Precision Craft Model E7 Running Poorly

[Herc Driver]

Excellent ideas...thanks.

I added a tiny amount of oil to the wheel gearing, and performance seemed to improve slightly. But I'm going to pop the shell off and try to place some right on the worm gears to see if that helps. When I last removed the shell, you could look at the drivers from the motor and they were spinning straight and true, and both trucks were receiving equal amounts of rotational energy (from what I could tell). It almost seems like a track adhesion problem...but maybe I'm only convincing myself that that's the cause since I can't come up with any better ideas. It would be one thing if one of the trucks were not powered, or a wire wasn't making good contact, or an extra frame weight wasn't installed. (Which makes me wonder if this engine's center of gravity and balance are to blame...hmmmmm.)

But I'm going to try to add just a tiny amount more oil and see if that helps.

Thanks!
