    Post New 100hp Amphibian Seaplane Homebuilt

    To all good desingers out there
    What is needed is PLANS for a homebuilt , 2 place, 100 hp, amphibian seaplane some thing like the original Lake.
    Power should come from the geared and water cooled rotax or the 0-200 continental. Many people want to use some thing else because they have one.
    The prop can be a warpdrive.
    Folding wings so it can be loaded on a trailer (maximum 8.5 feet) and parked in the garage at home. No wires or braces on the wings.
    Basic panel without costing a zillion dollars.
    The airplane should be a LSA or regular home built. The designed airplane should be built , flown , and photographed so anyone can see it. If a good plane is designed and built many people would buy the plans including me!

    I visualize a flying boat based on one of the Kolbs... Hmmm, maybe THAT'S what I should design and build one of these days...

    Hello
    Where I live the water gets hard in January. When I climb to 3500 feet (2000 feet above the ground) all you can see is lakes (lots of them). Not wanting to land on the ice I have to land at an airport. Here I can buy 100LL and see ann A&P. If you land a regular seaplane at an airport it buggers the hull or floats. Some people don't have any water. As the body ages it gets hard to get a 1st class, 2nd class, or 3rd class medical. The LSA only requires a driver's license. Because of this I want an Amphibian seaplane.

    And then there used to be the Avid Catalina - maybe there a few secondhand ones around.

    Avid Catalina? I saw one on Barnstormers a few weeks ago. It only had 2.5 hours on it. "Only flown once, needs major hull repair. . . "

    Can we say "in over our heads", kids?

    Hey Lee,

    Look at the Osprey at http://www.ospreyaircraft.com, or the Volmer VJ-22 at http://www.volmeraircraft.com.

    Hello SteveAir2
    I took a look at the two planes you mentioned. The first one is a posibility.

    That is a levitated Airmax. But it has struts.

    Re: New 100hp Amphibian Seaplane Homebuilt

    Thanks...I was talking to a Gentleman Yesterday that was telling me of his amphibian project. He told me the name of the design and for the life of me I cannot remember it. It started with an A possibly and he told me it was Canadian and a very obscure design. I don't think it was an Airmax. I've been pulling my hair out trying to remember the name because I wanted to look to see what it looks like. If you hear of a very obscure Canadian Amphibian design that starts with an A...please let me know...

    The Airmax is sold by a company in Brazil I mean Brasil. If you can't remember it is normal. The disease is called CRS and many folks have it.

    Hello
    A ready built airplane almost fills the bill. It is the Colyaer Gannet built by a company in Spain. They only sell ready to fly airplanes for the LSA pilots. They do not sell any plans. They power it with the Rotac 912 ULS engine which is a flat 4 , water cooled , and gear reduced. Close but no cigar.
    This is what I want to build -
    Wing span and weights like the Colyaer Gannet amphibias seaplene. You can use MSN search to bring them up.
    Fuel Capacity = 35 gallons
    Range @ 75% = 7 hours no resrve
    Speed = 120-125 @75%
    Power = Continental O200 or IO240
    Water Flying magazine has a nice write up in issue number 155 dated May/June 2006.
