Edgar,

Depending on the power you choose the DV8R will have a very short grass field take off capability, after all it really boils down to weight v thrust and lift. I hope to be done with my prototype within two weeks and I will let you know it flight envelope then. I expect to have parity with those other models in slow flight and take off distances.

As far as the DV8R looking like that other model, I guess that is true in as much as an F - 18 looks like an F - 14 to the uneducated due to the twin tail design. It is a little like suggesting that the Airbus looks mysteriously like a Boeing. Of course it does because there intended purposes are the same. But the DV8R was drawn by me as an extension and refinement of my AV8R almost a year and a half ago - I had not seen that other model. Also if you look at a three view of both you would have a much better chance to see how different they are. My AV8R was drawn as a twin tail over 3 years ago now and has proven a good way to put the engine where it is . If you think about it for more that a few seconds there are only so many ways to put a jet blast of 650 degrees or so down the centerline of a model. There is a reason most sport jets follow just a few current examples. Also should you ever see the two together you will see quite a bit of difference in many aspects.
