Lee, I think 10-12 volts on any of my Williams engines would launch them into low earth orbit.

This thread suggests that there was an error in the advertisement and that the scale hudson has no chuff. I have no personal knowledge either way other than what is written in this forum.
The 5543 has a "chuff" sound in it, the 773 does not.
Quote from: Ron Sims on September 17, 2009, 07:27:07 PMI am surprised at your loss of speed. I re-wired my semi-scale GG1 to series wiring and it is still plenty fast. I limit the top voltage to about 12 VAC to prevent the engine from launching on my 48" diameter curves. Slow speed operation is much improved. Are you sure that both motors were operating?
You will indeed lose top speed, but there can be another drawback. If your brick, or transformer does not put out at least 20 volts you may be unhappy with just how much speed you will lose. With my Z-1000 which puts out only about 17.00 actual volts at top speed my Williams engine was too slow. I switched my engine back to original wiring.
