That is great news, well done. Some friends of mine were suggesting that the wind rocking could perhaps be exaggerated by the large flat area on the back of each float, it...

The Vee and hull lines that I have...

It is the Akoya. It is real, although that photo may be worked up a little.</p>

Go to this site and you can find a lot of information about it. At the moment they have flying prototypes but are...

Cougar429,There is a reason why we are not all driving model T Fords, it is because people with vision worked together to discuss and implement possible options for improvement. In it's day the...

RE: Northstar mods - Tell me what you think

Apparently the foil aids quite significantly in softening the ride through the rough as well as getting hull up out of the water quickly. I have ridden in a large hydrofoil boat here in Vietnam, I...

I am getting old, my fingers work faster than my brain. </p>

RE: Northstar mods - Tell me what you think

Sorry, I forgot to add.</p>

A hydro vane in water only needs to have 1/1000 of the same plane ( wing) area at a given velocity to achieve the same lift as a wing in air. So only a very small hydro...

Alasdair,</p>

Actually if you read my post again you will see that I have not missed the point that the reflexed ailerons provide a downward pitching moment. Of course this is quite true when the...

RE: Northstar mods - Tell me what you think

If you watch some footage of delta aircraft taking off you will see that a very high AoA is required for take off. Even with the later designs incorporating close coupled canards the minimum AoA at...

If you would like to see some very interesting testing by the experts, Google " Langley Tank Testing " you will see that many transonic jet seaplanes designs were tested.</p>

RE: Northstar mods - Tell me what you think

Up elevator does not change the lifting characteristics of the wing, it changes angle of attack.</p>

Skywagn180,</p>

Just reading your original post and note that you are using elevons as well as elevators. </p>

I have been reading up a lot on delta designs and I came a cross some...

RE: Northstar mods - Tell me what you think

Hi Flybyjohn,</p>
