Where does the step on the floats go
 
I am putting a set of floats on my super Stick 60 and not sure where the step should go in relation to the wing.

On a 10* angle aft the CG. (Like the tire contact patch of the mains are about 17* on a tricycle gear model.)

thank you my friend. Have a Happy Thanksgiving.

And that'd be measured from the actual CG, not the CG's front to back location on the wing.

This might help you visualize the location.

It goes on the bottom

Sorry Gene, couldn't resist :D

What in the world would I do without MinnFlyer.

On your installation You want the airplane to balance at the same location on the floats as it does when it flys on wheels.

That CG you already know on wheels so after the struts are made up and the floats are mounted as per above with the CG/step relationship it will no longer balance at that point and most often it is tail heavy a little. Manny times a few ounces of lead in the bows of the floats are just the trick. This is about the only time I ever suggest adding lead but doing it this way you will never have to rebalance the airplane agine when changing between wheels or floats. Don,t add any lead to the airplane only to the floats.

Many of the fellows tend to make the float spread a bit to narrow so turning back downwind the airplanes tend to get easily turned over. I would suggest the float spread be at least one quarter of the wingspan on centers. Note this is a little more than the average spread of wheeled landing gear.

If any of you are considering floats, here is a guy who knows floats. And you can't beat his prices.

Directly under the CG with the plane in flying attitude.
