| Subject: | Re: float rigging |
Peter, I'm glad you are putting some effort into the research. I only
have about 200 hrs on floats and most of that is in Alaska flying for an
outfitter. Half of the time (taking clients out) the plane was loaded
very heavy and of course the weight was is the back. I can only think of
two times I had to load the float compartments. By the way, I am putting
together an S5 and eventually want to take it to Alaska on floats. I
believe if I had a choice, I would favor the CG to the safest point
forward on the floats because of the tendency to pile in gear to the
aft. This includes long items tied on the floats. But I don't suppose
you will be using the kitfox this way. Another consideration is how the
plane actually handles forward and aft loading of the CG on wheels.
Remember, I am used to maximum performance of the aircraft because of
the generally cooler weather up there and I have not flown the kitfox
in any configuration except for a demonstration flight with tricycle
gear in Caldwell during the summer. Good luck and keep us informed!

Larry I tried Kenmore but thay had nothing.
Noel's method sounds interesting and I plan to try it when the ice
goes out.
After asking around I now have five approaches for locating the step
relative to the cg:
One was a fixed distance for my particualar plane (which has worked
in the past but puts the step closer to the cg than the other methods);
another used the 50% chord point (and was argued strongly by a long term
aircraft and float designer); another puts the step on a line 5 degrees
aft of the cg. another used 1/3rd the width of the float; and , finally,
Noel's method to calculate the center of bouyancy of the float. There
is likely a similar bases for Noel's and the 1/3 width method which may
also be related to center of bouyancy.
No one that I have asked has ever seen any document on this.

If I read the documentation on my modIII-A the weight is furthest
forward
at the lightest load. In my case that was empty tanks and a 140lb.
pilot.
I don't know any one who flies in this area and weighs in at 140.

MessageYes, and that was my point. The cg should probably as far forward
as safely possible when the aircraft is lightest. Then as the load gets
heavier the cg moves aft. This affects the performance of the plane
getting on step quickly. As a general rule, the quicker you can get on
step the better.
