Most 8's have the mushroom rear rudder pedals, so it's easy to install an internal rudder trim....no aero drag, no additional mass aft of the hinge line, infinitely adjustable.

Drill a hole in the mushroom cap on the right side. Add a bungee and a bracket as pictured. Place the bungee hook in the hole and adjust the tension while in cruise to center the ball. Might need to re-adjust once a year. Unhook the bungee for descent, when the airplane may like a bit of left.

My mistake. For some reason, I was thinking that the requirement was 180.

Default Rudder trim....

During and after my flight testing with wheel pants off and on, heavy wing balanced, I still found I had a slight bit of rudder I needed in cruise. Seemed to be consistent regardless of speed. And I had built a little offset in the vertical knowing this was probably going to be an issue.

SO: got a piece of pine and carved it into a long, flat skinny wedge. Duct taped it on. It was on and off several times before I found how thick and where to put it. Then flew it for a while with that in place. When I was satisfied with where it was, made one out of a slab of scrap aluminum from my build. I still duct taped that on and flew it to make sure it was right. Has been on ever since. No adjustment necessary and cruises feet on the floor.

No worries! When I was looking this up before deciding on this solution, I guessed it would be 135 degrees, same as ships. I wonder why it is different? I think ships came before airships!
