 Posted: Mon Dec 10, 2007 6:22 am Post subject: My Electric Rudder Trim. |
 |
|
I have finally finished my Electric Rudder Trim on my RV-10 this past weekend. The airplane is now back together, but the weather in the mid-west was freezing rain all weekend and I didn’t get a chance to flight test. But initial testing with a fixed trim tab would indicate that this should meet my design requirements.
Pictures are suppose to be worth a thousand words, so I will save myself the typing and post lots of pictures instead.

Ray,
Your trim looks great!
Any chance you would document your dimensions and procedures so that others may copy?
Thanks,
bob

Hi Ray,
Thanks for the post. One thing that isn't clear from the pictures is how you reinforced the tab itself after it was cut from the rudder. Did you add a spar of some sort?

Sure, I can do that. But I would like to wait until I get through the flight testing to see if the size of the tab, travel, etc is correct

The tab was made with new material, not using the piece I removed. This way I was able to rivet the control horns to one side before riveting the trailing edge of the tab. The tab has a ¼” think balsa Spar with two layers of glass behind it. The balsa is there just to create the correct gap. I also did the same to close in the top and bottom of the tab.
Thank You

Yes, I re-enforced all around the perimeter of the cutout for the Trim Servo. You can see the angles on all for sides of the Servo plate. Also I created a spar where the trim tab hinge mounts to. You can see in the pictures there are two rivets above the 5 screws because I wanted to run it up to the next stiffeners in the rudder. I tell you it is very strong is this area, likely over-built, but that is better than under-built.
Thank You

Ray,
Did you reinforce the Rudder where the tab mounts? Just thinking about any oil canning and structure support needed. Hope it works as designed.......time to PAINT yet?

Did you actually tie into the rudder stiffners with the new spar piece which is infront of the trim surface cut out or is it only tied into the skins?

It is just tied into the skin and then the triangle section is glassed in all the way to the trailing edge.
