Thanks for the "heads up" on the water plane forum! Had not seen that one....

For handling in the air and on the water and most importantly dryness of the platform you can't beat the Sea Dart. I have flown on the water since 1966 and have 11 water planes including a Polaris, 3 Capricorns, Spruce Goose, 2 Sea Darts and Float Planes. Check out the Sea Dart.

Got lots to read -- THANKS!

Thanks Steve!
I do a kind of box for the fuselage and put some 3M glue and apply tape for the sinking zone of the fuselage, never had a drop of water inside.
Sorry for my english, I hope you understand!

Great way to do it! Thank you....

Otto, I liked your video!

I had read about the sea dart, and kind of passed it by, but this is making me give it a second look! Thanks.

I have a large one and a small one. The original design is in between. All fly the same and are crowd pleasers.

Otto, what is the size of the small one? Did you just scale the plans?

What kind of motor / prop did you use for the small one?

Thanks!

My small one is 19" wingspan and is a direct scaling of the plans. I fly it 3s with an AX 1806N, 2500kv motor and a 4.5 x 3 GWS prop. I dropped the engine inlets and just went with a nice aerodynamic faring around the electronics. A $5 clone receiver and 3 HXT900 servos make for a low cost investment.

That sounds like the ticket, Otto! Do you have any pix of the small one? I'm interested in where you mounted the electronics, and how you keep it all waterproof....

Here are some pics. All electronics are in the diamond enclosure; dump the original engine pod design, too much drag. Elevon servos are on their sides and rudder servo is upside down in enclosure. My battery fits snugly in the fuse cutout and is exposed. I seal everything in but the thin wire pushrod exits through the Depron. The top of these planes stay very dry and they are very hard to flip. Rudder is very effective on the water or in the air.

Nice way to do this, Otto. Thanks for the tips and pix!

I vote for the polaris...

I've not seen the polaris in person, but hear it's good. Aero Model and the AMA is giving one away for free. I think you have to register before the end of the month though. http://www.modelaviation.com/aboutusmodelaero

Question: I assume the ski hull has to be sealed to prevent water from entering. What is the best sealer for this? What do you guys use? Mike

On the sealed hull area I use Gorilla Glue; it expands to fill any gaps. I'm careful to use a thin bead on all edges and no water. I then trim any excess when it gets to the rubbery state and before it gets hard. On the rest I use foam safe CA.
