Summary:
Participants will design and build an electric motor driven, radio-controlled mostly Foamboard Seaplane model of a Historic or Fantasy Seaplane, demonstrate that it is capable of controlled flight, and release the plans freely to the community. At the end of the design portion of the competition, a panel selected from the Flite Test forums will score the entries and select winners from the completed and flight-proven models posted on the forums.

Objective:

• Celebrate the venerable Seaplane be it float planes, or flying boats
• Foster interest in building foam board model aircraft from community plans
• Promote designing and building as one of the aspects of the FT community
• Compete in flying events where any level of experience can be a winner
• Engage in some friendly forum banter

[leaded50]

i suppose (for first time) its possible i will participate with one plane of my list for a long time. Im soon used a year to gather info on the plane, and got some, but not all wanted. The Yokosuka 12-Shi Special Flying Boat (H7Y)
https://forum.flitetest.com/index.p...okosuka-12-shi-special-flying-boat-h7y.66994/

said to be the plane, not veryfied though.

One of my favorite aviation stories:

 

[Monte.C]

i suppose (for first time) its possible i will participate with one plane of my list for a long time. Im soon used a year to gather info on the plane, and got some, but not all wanted. The Yokosuka 12-Shi Special Flying Boat (H7Y) from 1937-39 , a real mystery. The fact that our time has not reached any photos or explanatory drawing of the project. Referring to the authoritative sources: According to "Encyclopedia of Japanese Aircraft 1900-1945, Vol. II Aichi / Kugisho aircraft" (Shuppan-Kyodo Publishers [Japan], 1966), the project of a flying boat H7Y was so secretive that no one outside of this project does not knew about it, this is due to the lack of pictures and diagrams. There's also mention of the use of a flying boat diesel engines Junkers Jumo-205C, a few pieces of which was purchased in Germany in the late 30s. Japanese also carefully studied the German experience in the creation of a similar aircraft - flying boat Dornier Do-26. There's also the second volume Encyclopedia alleging four-circuit H7Y, in which the German Jumo-205C engines were installed on the Japanese boat in pairs in tandem, rather reminding scheme Dornier Do-26. Renowned aviation historian Tadashi Nozawa said at the same time that the Japanese project was a twin-engine scheme".
This photo is said to be of the plane.. but it isnt veryfied. And its different opinon on how it was, 2 or 4 engines, where the wingfloats was,eg.

My plan is use what info i got, as the "Davis-style trapezoidal wing shape ", the bigger spinners than on the Dornier, twin-engine.... and follow some of the fuselage design from the Dornier, since its said had much recemblance. Till july is should perhaps can make it

Absolutely beautiful entry.
You're not kidding anybody. Once you start it'll take you 3 days to complete.

I saw this as a joke that Walter Extra made for April fools day, and I quite like it. Probably will draw one up for the challenge. It would be nice with a 36" span on a C-pack

What i will do is i will take a 3 view for an extra ng, and tweak it from there. The hard part is seeing if it has a taper to the trailing edge or not

Ha,ha Ill try be slower (or need, to get a more instructual build.) At moment, i have no spare servos, no foambord eg.. so at least it will not be ready this week

 

[DinosEatPeople1]

I would like to build an Messerschmitt M23 seaplane for this. Found it just a tad ago and will be trying to build it soon.

Fairly simple design and I found a 3 view of it. Floats may be a bit iffy for me but I will figure it out.

 

[FoamyDM]

I love what I'm seeing so far!
My be question is if all these are an official entry or not. @leaded50 I see your is official.

Haven't quite decided yet. I'll either do an Air Cam or an Extra AFD. Leaning towards the AFD at the moment though!

 

[Hondo76251]

I'll throw my hat in the ring (or the pond in this case) 😄😉

 

[leaded50]

yeah.... then i got a extra reason to build that seaplane now.... even if the planned McDonnel XP-67 Moonbat build got pushed down the list.

Yeah I will do it. I need something to get me off my phone.

 

[The Hangar]

I'm in, I'll be making an Icon A-5.

Put in for Both? no limit on entries. And no entry FEE!

 

[Matthewdupreez]

i would be in but i don;t now how to fly and i only have one c motor that i am not willing to risk....

 

[FoamyDM]

OK - I have been on a finish-it or toss-it kick lately. In that Vain, I have 4 planes wish to review and finish as part of this challenge. I start my Entry with the Vought OS2u Kinfisher from of the back of the USS North Carolina.

Get another. until it arrives, Plot, plan, Scheme and Build. Are you worried about a failure in the water costing you the motor system?

 

[FoamyDM]

Are you looking for ideas or inspiration? me too! post them for other builders to get excited about and join in.
Not all are Seaplanes, but there are some GREAT ideas here:

The Chaparral Aircraft <Morskoy 'Ezh'> ("Sea-X")

a different take on it.

and a Favorite, just because:

Build a pusher plane, that’ll protect the propeller and motor.
