Too much information.That is some knowledge and experience, thanks for sharing with us. Your advices are always very helpful for me and others.
Now, for a regular average 150-180hp Super Cub on Wipline 2100 amphibious floats:
1: Where would you put the step in relation to the 63" wing chord, float top level?
2: How many degrees from the float top to the bottom of wing ?
3: Rudder height from ground, float top level?
So far, what I've found:
1: step @ 38.5% to 50% of wing chord
2: 3.5* to 5.9* float top to the bottom of wing
3: 10'4" to 10'6.5" (easy part hahahah)

6 degrees to the bottom of the wing will give you 7.77 degrees to the chord line. This is a lot. That will give you an angle of attack while you are on the step of 15.77 degrees. That means you will have to land each time with the nose at least that high. If not you risk digging in the bows. If that is what you want, make sure that you can stretch your rear strut as much as 2". In the end, I think you will be happier with about 1-1/2 degrees less.
I was away from home all summer. I'm now back and installing Clamar 2180 amphibs under that red plane.
Do you guys think it is an acceptable method to attach the 5/16 fly wire clevis to a 5/16 i-bolt, like shown in the picture bellow?

Glenn,Your trying to lock the floats into a rigged position, why run the wire to an aluminum strut when it would be easy to run it to the float anchored to the float attach bracket?

I plan to use those stainless steel hardware for my 3/32 float rudder cables.
How can I crimp this little ball shank??

Oli, do leading edge slats change your AOA significantly on landing? I’m interested to see how it performs….it really looks nice on those floats. Great job
6 degrees will produce high drag with increased nose down pitching moment for cruise and climb. In addition to the high drag for cruise you will need a lot of nose up trim which is more drag.That is why I've went with 6 degrees. Hope it performs good on water and on land, will see next spring..
