I'm not sure they designed the speed control to have a 28V input. I = think they would expect you to put their 28v ->12v converter in. The = latter may also be just a resistor but the point is they worked out all = the power dissipation requirements etc. Mike, I looked at the safety-trim. I like the idea but it gives you limited = protection if you have the tru-trak auto-trim module. The latter = totally replaces the manual trim circuit when it's active and has it's = own speed adjustment. I looked into inserting a speed control between = it and the servo and it just doesn't work in a straightforward way. = Since my concern was auto-trim run-away, I felt like it didn't do what = was needed. That said, I don't know if I would buy the auto-trim = module if I had it to do again.

Jim,
 
The simple way is to use the Ray Allen speed controller.
 
 
But how much fun is that?
 
I installed the Safety Trim which is a speed controller with a two = speed=20 feature.  I set the air switch to go from slow to fast at the top = of the=20 white arc.  I now have about 40% speed in cruise and full speed in = the=20 pattern.  The Safety Trim also has 3 second timeout and reversing = features=20 in case of a stuck trim switch, and it handles two sticks.

It=92s=20 worth asking, in politics anyway, if we can=92t gather enough=20 credible evidence that supports our position, is our position = worth=20 supporting?
