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! ----- Original Message ----- From: Peter C To: seaplane-list@matronics.com Sent: Friday, March 16, 2007 12:07 PM Subject: Re: Seaplane-List: float rigging 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.

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.

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. ----- Original Message ----- From: Noel Loveys To: seaplane-list@matronics.com Sent: Tuesday, March 20, 2007 6:46 PM Subject: RE: Seaplane-List: float rigging If I read the documentation on my modIII-A the weight is furthest forward at the lightest load.
