In respect to the model in the picture above there are certain characteristics that really echo the model I manufacture when i made the plug decisions had to be made in regard to it's construction which i will not go into,these items are exactly the same on this plane while it is possible for someone to make the same decision what are the chances of this happening, also if i where to add the length of the peetotubeto the over all length this would bring my model to over the 70" fuse length add a few inches of exhaust outlet as can be made as a separate component and there it is the wing is not a problem to add or subtract length.
So I take it from what is said in the above posts that everyone believes it's OK to say take a Graupner hot spot add a few inches here or there and call it my own because the new model now is of a different dimension.
