Der ist Ihr Verlust!

Very cool project, and Stevie Ray is the KING!!!!!

Love your video. The plane ' neat too.

You'd have to remove the landing gear both to make the fuselage watertight and to reduce the drag enough to permit takeoff's and landings. The shape of the belly would also have to be changed.  Even then the drag of a water landing would probably tear the fuselage apart, assuming the drag on takeoff didn't destroy it first.

Now, if you wan tot design an ultralight amphibian from scratch, you might take a float made for another p[lane and use it for your fuselage....

@Joesolo13 I didn't mean to give you that idea... This media is not easy to pass on technical ideas, so I would suggest that you consider a posting your questions at the sky pup club at Yahoo.

@dodger2952 did i annoy you? sorry, your just the only person to respond at all to my questions

[Joesolo13]

@dodger2952 oh, and the comment "I've never heard of anyone actually trying it." just made me me really want to build it now. and my brother agrees.

[Joesolo13]

@dodger2952 wow, 8/10 of a milimeter...yea that might be a problem. though i think i remeber reading in one of the letters on the skypup site someone made an emergency landing in a river once and the plane survived. if i was able to reinforce the bottem of the sky pup with something lightweight it might work well. i know theres a weight limit but everyone that wants to fly it is under 200lbs by a fair ammount.

[dodger2952]

This approach may be possible. However do not under estimate the amount of weight it would take to seal and reinforce the sky pup underside. Plans call for 8/10 millimeter plywood. It's not even strong enough to stand on, so water landing would most likely burst completely through the underside of the fuselage with dramatic results. Also you have to add some kind of outrigger floats to stabilize the aircraft on water. It might be doable, but I've never heard of anyone actually trying it.

[Joesolo13]

@dodger2952 what about putting a water tight hatch on the hole for you feet so no water can come in? that should only add another pound or 2 at the most.
