Paul,

I would say the added value is more exposure.

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 feature. I set the air switch to go from slow to fast at the top of the white arc. I now have about 40% speed in cruise and full speed in the pattern. The Safety Trim also has 3 second timeout and reversing features in case of a stuck trim switch, and it handles two sticks.

I know this has been discussed before and I’ve given a cursory look on the archives. But is there a simple way of adjusting / changing the speed of the servo to slow it down some for pitch trim in a 4PT? The pitch change is too fast at speed where just a small bump has too much effect.

It’s worth asking, in politics anyway, if we can’t gather enough credible evidence that supports our position, is our position worth supporting?
