I saw someone was selling seets of 3D printed pontoons that attach to the Phantom, anyone tried them?

You have a link?
It would help people understand what your asking

Wow! those would have to be pretty bullet proof before I would attempt to land my P3 on water. It would seem the P3 would be awfully top-heavy for something like that.

If you mean things like:
http://www.shapeways.com/product ... 3-fusion-marine-fm1
http://www.shapeways.com/product ... loating-dji-phantom

They are misguided concepts.
Note the vendors haven't tried them and don't even list the weight.
You'd have a tough time flying with those things if you could takeoff at all.
Rather than enhancing your flight safety they are more likely to be detrimental.

Fly the Phantom the way it was designed and it will fly a lot better.
And that's beside getting in your camera view all the time.

I would not even consider them. The water damage from the spray caused by the props would not be worth the experience!

Ahoy matey! The Phantom's center of gravity is too high for these things to work effectively much of the time.

Look rather phallic to me!!

What's funny is, the second link's product is $134, and at the very bottom, it says the price is for just one side - so you need two of them to float ... $268.  Ugh ...

The first link is not for sale.  Which is probably a good thing.  The second link, as stated above, the price is just crazy.  

How about some skis so we can land in the snow!!!

You usually see what you want to    rofl

Why absurd?
A friend of mine actually bought a set of these direct from their website (they're only $40) and they work exactly as advertised.   Battery issue caused his P3P to go into auto land over a lake.   onlt thing that got wet was the compass at the bottom of the leg and that still worked.   Saved the day.

And how much did they affect flight performance?
I'm interested but the seller won't answer that.
Can your friend say what top speed they can get in still air with those strapped on?

Sure.  He's in South America a the moment but when he returns I;ll ask for ya

"Note: To make the FM1 water proof a coating of enamel (not supplied) is required to be sprayed over its structure. This is a concept 'beta' design and at this stage unproven. If you purchase this product we cannot guarantee that it will float or perform as advertised. We will continue to develop this product in the future."

Now that's some funny stuff. You have to waterproof them yourself and they're not guaranteed.
