Subject: REFLECTOR: trim motor control

I'm in the process of wiring the trim motors and I've been wondering about something for a while:
The trim motors are 24v motors. It is my understanding that the choice of a 24v motor on a 12v electrical system was done to have the motor run at a slower speed than an appropriately rated motor would. And that this allows better trim control.  I don't know if this is accurate, it's just something that I heard.
My issue is that I have a 24v electrical system. I've looked for 48v versions of the trim motors but they were either unavailable or way too expensive.
So I'm looking at a 28v-14v step-down converter.
But before I pull the trigger on that purchase, I was wondering if:
1) My understanding of the 24v motor on a 12v electrical system was correct.
2) If anyone has come up with an alternative to slowing down the motor speed which would save me from installing a step-down converter.
Thanks,
Don
