Besides that I think you have the looks nailed, beautiful work.
Thanks Greg.

I agree with you about the intakes, ideally they should be made by bending 3mm depron. I went with this design to keep it simple and use only 6mm sheets. The corners are supposed to be sanded round, I will post a picture once I'm done painting.

I use a scalpel for the cutting.

I've added pictures of the completed model to the first post http://www.rcgroups.com/forums/showp...60&postcount=1.

The paint job turned out really horrible, I hated putting my custom made vinyl decals on it.

Did some water trials on a small pond this afternoon - not totally successful. It comes on to plane easily and I think it will take off and land ok, but at slow speed the wings do not have enough boyancy by themselves. In a cross wind the large fin wants to roll the plane over. So I will have to add some wingtip floats.

That's no big deal. Make the floats look like drop tanks or bombs.

Another idea, you may just get by with an extra layer of 6mm foam in the same shape of the tip at the tip.

On the real Seadart, there are "fins" (for my lack of knowledge of what they are really called) on the bottom of the wings at the tip. They are probably to help the plane track straight. You could make your floats to match them. Just an idea.

Yes, thanks. That is what I'm doing. I'm using the shape of the "fins" and just increasing the size to work as floats. I also have to reduce the elevon span to make space for the floats, but the plane has more than enough control authority so it should be fine.

Thanks for your idea too Greg.

There ya go, that looks like it will work great. I really can't wait to see video when you can do some. I live on a lake and would love to make this plane but I lack the nerve to fly over water for fear of a "splash down". Will you be waterproofing and of the electrical components?

I can get some video off grass tomorrow, but I'll only be flying off water when I go on holiday next week. I'll be able to post video when I get back in January.

I'm not waterproofing anything (which does not mean it is a bad idea ).

If you are looking for a well proven waterplane design, check out the Polaris thread in the scratch built foamies forum. Also tons of useful information on waterproofing and more.

The floats seem to have solved the water stability.

Here is some video, flying off grass:

Depron Seadart (1 min 18 sec)


Most of the flight is at about 50% power and never more than 80%, as I was trying a 1250mah battery for the first time.
