Thanks for the advices.
clarence commented diodes were an invitation to disaster—would like to know the reasoning behind this? I researched the use of diodes to drop voltage on this forum and others and found this solution many places. All noted they would get warm. This is warmer than I expected. None mentioned dangerous. I should note I am not skilled in this area at all!
may try bigger o42 curves. Good idea.
may just let the youngsters (two actually—five and one and a half years old) have at it and learn by experience!!
the dc conversion idea sounds interesting: what should I look for and where for a dc transformer. And what do I need to do to the engine to accomplish this. Remember the engine runs fine now it just has too much available power from the little 45w 16v max 1025 transformer.
