    Another float question

    Hi Jim and other seaplane fanatics!
    I've been bitten bad by the float plane bug! I've read so many articles on floats my head is spinning! I need some advice so I don't over-spend on new floats, and to calm me down! Lol. I'm putting floats on a couple planes, one of them being a Great Planes Giant Stik. The plane is 13-15 lbs. Powered by a OS160fx. Lots of power! I've determined I need about 52" floats (prop to rudder hinge line is 67"). My main question is: In your opinion, should I go with flat bottom or v-bottom? I've read flat bottom are better. Seaplane supply has both. I'm leaning towards Slocan floats though...any opinions would be greatly appreciated!
    I have been flying an easy sport 40 with floats and an Ace Seamaster which I just love! I'm also going to put floats on my Great Planes Cherokee. Thanks again! Troy

    RE: Another float question

    The Giant Stik will be off the water so quickly that the float-bottom means little for takeoff.  I find that V-bottoms don't skip as much when landing.


    I had a H9 super stik, and installed the floats with identical H9 landing gear legs.  With the level fuselage bottom, that gave me zero incidence and it was necessary to crank in a little flaperon to take off.  Moral: be sure to mount the floats with the nose drooped a little. 

    Of course, in WY, Flat-bottom floats probably work better on snow and it should be snowing there in a couple of weeks..:-)

    That's great advice Jim, thanks a lot! We have to deal with the wind a lot here also along with the snow.

    RE: Another float question

    If you are working rough water in the wind the V bottom is the way to go, the only suspension per say with floats is the V bottom which cuts the water on contact as does the V bottom of a V hulled boat. If you have been on rough water with a flat bottom boat and then switched to a V bottom boat then you know what I mean. 15 lbs is enough weight that if you do not get the landing right or you are landing back into rough water the V bottom is the preferred configuration and a 18 degree V is preferred. The H9 1/4 scale float kit will float easily float 15lbs but they are 48" in length and may be just a bit short for your fuse.

    RE: Another float question

    Both preform well, the flat bottom tend to taxi better when not using a water rudder,, Only real Plus I can think of. With a Stick flat would be fine.

    Here is something to think about though,,
    What if you get board with the stick and want to put these float on a nice scale airframe? The V-bottoms will look a whole lot nicer

    Now if it were me,
    I'd build a set of Taildragger floats for that plane like these http://static.rcgroups.net/forums/at...imerstatic.jpg
    What that configuration does for you, besides looking cool and more match the WWI theme, is allow the plane to have more rotation angle taking off and landing, I see many times on the lake guys bring these type planes with conventional floats and the plane has to go 100 mph before the wing has enough lift to fly. I had a 20 size Top Flite Elder set up this way and it was a hoot watching that tail raise up and the 2-float touch and goes. The are pretty easy to fabricate yourself out of foam blocks.

    Hot-timers.
    They are in his gallery. http://www.seaplanesupply.com/Float%...%20Ritchie.jpg

    He has posted 4 or 5 pictures of planes on the Hot-timer floats.
    I can't speak for mark, but an email to ask the question is not expensive (yet).

    RE: Another float question

    Edit: here it is http://seaplanesupply.com/oldtimer.htm the link is gone from the menu

    On my Elder, I just sheeted them with Birch Veneer and sealed them with Spar Varnish,, I attached the only pic I can find,, fun little plane

    I think the natural wood finish would look good on a Stik

    Looked more like these
