Just bend the LE of the vertical stabilizer like Piper says to.

Only do this when the airplane is on wheels. The airplane MUST fly straight without the floats first.Just bend the LE of the vertical stabilizer like Piper says to.
Might note that this advice is on a RANS S7.I taped a 1/4" diameter length of aluminum tube, guesstimated it at about 6" long "would be about right", on the TE of my exp.'s rudder, on the same side as I was holding foot pressure. Once I found it was about perfect in all conditions, or close enough anyway, I hot glued it onto the fabric.

Hmmm? Interesting ! That's a new one to me.I taped a 1/4" diameter length of aluminum tube, guesstimated it at about 6" long "would be about right", on the TE of my exp.'s rudder, on the same side as I was holding foot pressure.

Try changing the power setting up/down, see what happens.Wow thanks again, good advice skywagon I won’t do anything major till I check it out on wheels. It is just a minor amount of pressure I have to apply to center the ball so it’s not out much. I have 180 hp in it and the plane is still the way I bought it, not sure when I’ll have it on wheels. For now the water rudder idea sounds good.
thanks again,
That is my preferred way of rigging a rag and tube Piper with a jack screw trim system. I hate external trim tabs and would rather make the surface go the way it needs to.Yes, but the concept works on any plane, and doesn't require drilling any holes and maybe looks less obtrusive, even unpainted like mine. Using tape, it is a good way to experiment, as it's surprisingly effective. I like the bending of the vert stab too, didn't know that was a recommended way to fine tune but it makes perfect sense.
Yes Steve, if on wheels. If it is crooked on wheels, then when floats are installed you will be incorrectly correcting an error. It must be right on wheels first.Does it fly hands off just not feet off? If so bend the leading edge of the vertical fin and it will fix your problem. Done it a 100 times and it works and is how Piper did it and described in the rigging instructions. I think trim tabs are lazy.

With the bottom of the wing, trailing edge of the flaps. Do not try and dink with the vertical fin until the airplane flies hands off in rol via aileron rigging or you will be chasing your tail till doomsday.On a related note. Could someone tell me where in reference to what is the correct neutral aileron position? With the stick centered, where are the ailerons supposed to be and what reference point do you use to measure it?
I know of a cub that changed the aileron neutral deflection position and it required rudder to keep the ball centered afterwards. Suspected that one aileron was deflected differently. It flew hands off, but needed a bit of left rudder.
No dealing with rigging back and forth between floats and wheels so did not know that. I would rig it and then rerig if needed on wheels or just add a trim tab and go back and forth if that is how the airplane will be operated. The float plane I maintain is on amphibs and does not go back and forth to wheels.Yes Steve, if on wheels.

Sort of, the wing is a bit concave on the bottom. If the wing is built right it will line up with the outboard aileron bay tip rib.
