Unbelievable,
If someone has nothing positive to say, they should try to restrain themselves and remember that this is a HOBBY that all of us enjoy. Some of us here, have forgotten that. I came onto International waters to learn from others experiences, and apply that to my own, to make my Hobby more enjoyable.
Now, to the best of my knowledge the Dumas Eagle was designed specifically for sport 40 competition. Of course if anyone has anything constructive to add, by all means please put your .2 in..
I personally have built numerous Dumas models over the years and theres nothing wrong with them. The Eagle I think is the most recent Dumas design. I'm not familar with the transom 'tail corner" sticking out though. It should be based on a scale hydroplane. The IMPBA rules are pretty clear.
What I would suggest is to try to lighten up the hull by making some lightening holes in all frames and bulkheads. I bought a right angle drive for my dremel and a router bit and cut holes, then cleaned them up with a drum sander bit....worked out great.
