Hmm... I see what you mean about drawing current off the motor, Peter. I
ought to double motor the thing, but that would mean losing the 3-axle
trucks, which I want to avoid. Ross, does your stuff run off one or both
motors? I'm putting the same load on my one motor, and if that's what
you're doing, it means there's hope. I'm going to try to hollow it out as
much as possible and concentrate the weight over the motor (thank god for
weight bricks!!!).
Thanks both.
