re dec drive, mine is still on 12v and no failure but it is making growling
noises for about 15 seconds after geting slewed to a new position, then
seems to quiet down. is this impending problems.
just what does going to 18 volt and new motor get you ??

I havent got any knowledge on these specific drives, but as an
EE the thing to know is what operating voltage these motors are designed for.
If its designed for 18V DC and draws X current, the power will be 18X. If
the motor runs on 12V DC then it will have to draw 1.5 * X current to run at
the same equivalent power. If the motor isnt designed for this excess
current (150% vs nominal 100%) you could end up with a fried motor in a short
time.
