Smith overhead trim

[JayH]

Hey folks,
This is going to sound like a really stupid question, but my brain is scrambled right now from too much thinking. For you Smith drivers out there, on the overhead trim crank, when you turn it to the right or clockwise, which way is your yoke traveling, up or down? I know on the side trim, cranking forward is nose down.(yoke traveling up) Transferring that same motion up to overhead, my trim seems backwards.(clockwise, the yoke travels down, which is nose up). I can see where you could reverse this on the side trim coming off the horizontal pulleys, but on the overhead trim system, the only way would be to cross the cable and come off the other side of the jack screw pulley. Mine appears to be correct based on several photos viewed, just seems reversed.

Thanks,
J

On a traditonal Piper like a comanche with overhead crank Clockwise is down same as a Supercub side trim which means the yoke is going up.

On a pa-14 clockwise trim is nose up

My Smith, clockwise is nose up.

Thanks guys. That was driving me nuts there for a little bit, but sounds like mine is correct. Appreciate the help.

Well, I think after not too soon, it would become second nature which way you need to turn the crank in your experimental Cub. It really doesn't matter which way you crank, within 1/4 turn you will know if you are going in the correct direction!

OR... you could put a placard on the escution plate that says :
Nose UP and Nose DN with arrows.

I always picture the crank as it passes next to the fuselage. As the handle moves forward , push nose down. Handle moves aft pull the nose up.

Now you know why brain wasn't working any more last night - I was driving myself nuts. Not a big deal, but you get to thinking about something long enough, you can't let it alone. You know, that "right on the tip of your tongue" thing.

I agree, once flying, it'll be second nature - regardless of which way it turns. Also, my indicator plate will be marked with "nose up" and "nose down".

Thanks again for the discussion.
