The normal Ray Allen travel time is about 15 seconds from = their website and I'm around 5-8 seconds. It would appear that Trutrak = will mod the autotrim box to limit the output voltage to 12v but I've = got a note into them to confirm this before I send it back. If that's = correct Doug then the trim speed should be more manageable. This is = also a safety issue because a 5 second full trim move is not easy to = live with in a runaway situation. Will advise shortly.
