Rudder trim

[Dusty]

In a recent post(regarding brakes)a comment was made regarding rudder trim.
I have to fly with port rudder(2stroke) and it does get tiring after a couple of hours flying.I shimmed the engine thrust line which made a difference but could still use a bit more trim.
A bendable tab would work for me but these look like an afterthought and may
be succeptable to hanger damage.
A while ago I saw what appeared to be a triangle shaped strip near the trailing edge on a rudder,it looked tidy and was near invisible
Questions. Is anyone using this setup,how affective is it,which side of the rudder does it go(does it push or use black magic to suck the rudder in the desired direction)?
A spring or bungy setup is an option,is anyone is using this and does it restrict opposite rudder movement?

I taped a wedge that I bought from somewhere, can't remember. you can also make your own out of balsa wood and tape it in place. go from 0 to 1/2 taper might be a start. I would say at least 4 inches long. now if you have to put in right rudder to center the ball, put it on the left side. the idea is the wind will hit the wedge and push the rudder. left rudder needed, you put it on the right side. nothing fancy about it. I taped mine on with clear packaging tape and than hit it with white spray on paint and it's been that way for about 5 years now.

weird, I copied the link, but it doesn't show. the right page, go to the search at the top and put in trim tab, and it will come up. plastic and you can cut it to the size you need.

Thanks this is very helpful, balsa sounds like a good idea.

Hi
I have used a balsa wedge on the ailerons of my model aircraft and it works very well and looks neat. I varnished the balsa and stuck it on with epoxy adhesive
Then painted it white about 6" long 1/8"triangle

That should be Jodel aircraft not model aircraft although it would work for models!

On this advice I ordered one of these. The full size works perfect for my plane. With the 582 it needs to be on the right side. It can hardly be seen on the rudder. I like this much better than using a spring on the rudder pedal that had been suggested to me. The avery wedge is 3/8 inch thick so it may need to be a little larger than if you make one out of wood and use the 1/2 inch suggested.
