Default elevator trim wheel

Anyone used used an elevator trim wheel ?
I have seen several discussions and one interesting picture in an RV-8 but no details.
I'd like to put a trim wheel in a center console of an RV-9A.

Thanks.

Rans aircraft builds a nice manual trim wheel that could be easily adapted to an RV. Have had this in mind for more than 15 years.

Search: Rans S6 trim wheel.

Would call them directly though.

Default Both very neat

Hi Gil

I was looking for a wheel for a mechanical system, although this MAC/RAC kit is very neat, backlit and all.

And George, that has possibilities.
RANs publishes
https://docs.wixstatic.com/ugd/6e941...1300a5bf15.pdf
and on page 34 has the trim wheel system. It's going forward however and not being familiar with RANs I'm not sure what it's trimming but it's a simple system so I would think it's adaptable.
My hope however was a trim wheel on a cam / worm gear adaptable to a single cable back without additional pully's. I'll look to see if RAM/cabletech has something.

Thanks for the suggestions.

Default Maybe a teleflex cable ?

I'm not terribly familiar with marine or teleflex steering but in looking at their methods a geared down teleflex cable might work.

Just a thought.

The Rans trim wheel drives a single push/pull cable, not pulleys and cable. Again, think it is worth a closer look.

ok, I get it. I was looking at an older RANS 6 type. The newer parts list has it. AC Spruce has it but the image is too pixelated to tell what you are looking at.
I'll investigate further.

Greatly appreciated.

Personally I think installing both a center console and manual trim are a mistake. I can't think of any advantage of either of those items compared to electric trim (takes up valuable space, weighs more, more complex, no autotrim available for AP, time to build and install, etc).

Default Navion trim wheel

Just following up on my pursuit of the perfect trim wheel,
is anyone familiar with the Navion trim wheel.

There is an image of it for other part on AC Spruce

https://www.aircraftspruce.ca/catalo...clickkey=16498

but I can't find the mechanism for the trim wheel itself.

This looks promising.

Thanks

Most certified aircraft with trim wheels for pitch trim control actuate by using a closed loop cable system ( a loop of cable that runs between the trim wheel and another pulley wheel aft that actuates a jack screw arrangement).

It would be difficult to integrate into an RV's pitch trim system.
