For best flight performance the floats need to be level when the airplane is flying at cruise speed. Any deviation, positive or negetive, will create excessive lift/drag which can result in the pitch sensitivity you mentioned. Proper float setup is a compromise between on-water performance and in-flight performance. Factors to be considered include airfoil, wing loading, power, desired flight performance, expected water conditions, and many more. The best setup is different for every airplane.
A blanket statement like that is misleading at best.
Enough. We have hijacked this great thread, and I, for one, would like to turn it back over to the builders of these outstanding seaplanes.

Cowboy,
those float are definitely wrong,,
you should always have some negative incidence floats to the wing,,, never a flying wedge like that plane appears to have

Yes it is a blanket statement
Maybe you can point out a situation where the statement would be false?
Do you have an example where you'd want negative float incidence? I'd sure be interested in hearing that.
Also,
I wouldn't have said Boo if Cowboy didn't post those pictures along with his statement obviously pointing to his plane as an example of a properly set up plane with effortless take off abilities. Funny in his follow up comments he says he just needs to "tap the elevator", but in the picture he posted he's holding what would apear to be full up elevator. Looks like a little more than just a tap to me. If you ask me it looks like he's fighting that stink bug set up in order to get to rotation angle.
You're free to disagree with me,, You're not free to tell me when and where I can post comments

Hijacking a thread is bad form. If you want to continue this discussion, please PM me or start a new thread.

I have sold the Custom Privateer for a price I couldn't refuse. I will be selling the Sea-Cat also. Anyone wanting a shot at it let me know. It is in good condition with a small piece of 1/8"soft balsa missing.

RE: Seaplane pictures
Like I stated in my post, that is just adding power before it gets up on step to help with rudder control because I don't use a water rudder. After it is up on step that much elevator is not necessary. Yes, it only takes a tap. Stink bug setup.....LOL

RE: Seaplane pictures
Scale, just so you know, those floats are NOT wrong. How do I know? I've been putting on floats for over 18 years, other than being a tad bit to tall, and there is a reason for that, "prop is big" I have flown Cowboys Husky several times and its flawless. People who put floats on planes do everything wrong, and some just "get it right" and think there an expert on it.
I KNOW your gonna tell me I'm wrong, and thats OK. But the fact is, is that this plane fly's perfect EVERY TIME, with no bad habits. The reason you have to tap the elevator is because like all good RC pilots, we fly with just a tad bit of "down" in it.
Every plane I have EVER done, including this one, have flown real well with the float set up that was put on it. and there is a reason for that as well. Just like EDO and all float manufactures will have in there install manuals. it is set up that way
Step,,,,,,,,,,,,,,,,,,,, just ahead of the CG 1/8 to a 1/4 inch
and deck of float,,,,,,,,,,,,,,,,,, level to horizontal stab
If you keep with this formula you WILL have a great fly'n plane, no matter if you put floats on a 330L or a Stearman. hahaha
Have a good day...Rod

RE: Seaplane pictures
Two pictures of my rudder and elevator float plane. Onlystationary pictures as it's difficult to take pictures while flying. The plane probably prove that a lot of power is not needed to ROV. The plane weight issome 2.5kg and it is powered with an old OS .30 that spin a 10X6 prop close to 10 000rpm. The take of run is like and overloaded Cessna 206 on float's, quite long. The first 5 meter or so in dispacement mode, then planing on the step and aft part of the float another 15m before it get up on thestep. On the step I need to keep the wing AoA low another 20m before lifting off and gaining speed at level flight before climbing.

That is a great example of floats level to stab and step in the right place.

RE: Seaplane pictures
Years ago I bought a Balsa USA Northstar from a fellow club member. After having
a blast flying it for one season, I lost it due to an elevator servo failure.
This winter I decided to build one, OS 55AX, 10x7 3blade, 6lbs 8ozs.
Hope this one lasts a little longer!

cool ! no cg issue with such a big engine ?

RE: Seaplane pictures
Thread says "Seaplane pictures" and nothing about the real thing,
So, I was going through some old photos a day ago, and stumbled onto the seaplane I once had. Why is everything great always "once?"
Anyway, thought I'd place it here just for the fun of it. Anyone know what type of aircraft it is?

RE: Seaplane pictures
Corsair-wb,
Yes, you are correct. In this case, a Lake LA4-200T.
Now what does the "T" stand for?
Get it right and you win FREE graphicxs or lettering! That's the mood I'm in. [sm=bananahead.gif]
