Tommy,

I'd first check to see if you are using all 5 inches of the Vans actuator. If you are still building check to see how much travel you need for the flaps to operate fully, if possible at this stage of your build. If 4" is enough then this would work. The next option of this type actuator is a 6 inch actuator. But of course it's physically 2" longer than the 4".

As you can see in the link you posted the actuator closed is 9.75" long and 4" longer when extended. The actuators with built in position feedback are a bit longer (about 1.25") than the ones without as these have a Bourn's pot inside the base to provide the feedback to your EFIS or flap controller.

If you need more than 4" of travel you could buy the 6" version and of course only utilize the 5" like the Van's actuator. But keep in mind the 6" version is 2" longer when closed. Just a guess.

If the 4" will be enough I have an extra 4" that I could sell you. If you need detailed specs I can give them to you as I can physically measure anything you might need.

These units only have 1/4" cross drilled holes in each end for mounting. They make brackets specifically for these to use as pivot points.

The end of the actuator does not have a threaded hole for a rod end. The actuator end is aluminum so you could drill and tap the end if you desire. Or simply machine a steel "U" shaped bracket that you could bolt to the existing hole on the actuator and then secure the rod end to your bracket with some jamb nuts.

The mounting options are endless and limited only to your imagination. Very easy to adapt to any mounting location or linkage.

Hope this helps.

Shawn

Thanks for the quick reply. It will be a few months before I have the wings on again. Will check the travel then.

Thanks
