Hi all is there any other amphibious aircraft you can build from plans besides the vj-22 ,osprey 1 and 2 and kingfisher ,i would be interested in single seat or light sport two seat plans
Also years ago someone was offering plans for all wood floats ,which were used on minimax in Canada but looks like they are no longer available ,thank you

Molt Taylor's Coot can be built from plans, but it is much bigger than an LSA

I recall a very simple airplane that used a flat-bottom hull for the fuselage and had some sort of novel wing arrangement on top (a Kasperwing?). It wasn't much more than a jon boat with a pivoting wing on top, IIRC. Maybe someone here will know more.

If you’re only looking interested in LSA then I would go the Zenith Aircraft route: 750, 701 or even the 650 XL on a set of Zenith amphibious floats. All can be built from plans.

Dear Vigilant1,
You are thinking of the Spratt Control Wing flying boat. At least 4 were built and flown. Construction drawings are accessible at:

Thanks very much. That's exactly what I was thinking of. (I couldn't get your link to work, BTW) Apparently not an amphibian, though, but a cool, simple seaplane. Looks fast (in a Buick Skylark kinda way) just sitting there.

Avid Amphibians are not plans built, but an old kit is probably cheaper than raw materials.

The simplest way to get a inexpensive seaplane is to put floats on something. Muk Tuk built some interesting wood float kits, To my understanding Fisher Flying Products now has the plans for them but would require verification. Why they do not market them or if they sell the plans I do not know.

Although not "homebuilts" per se, there are several weight shift "trike" type aircraft that have been mated to small inflatable boat hulls, Zodiac style boats, etc. You can see hundreds of youtube videos of these things buzzing around almost every tourist-trap blue water beach and tropical resort on the planet.

I'm sure somebody has done an amphibious version that can roll on solid ground in addition to the floating raft ?
