OK my mistake i had another look at the last pic you posted and it shows up a bit neater on there...
Have you figured out the transom and radio box stuff yet? Did you decide to go with the same extender mount you have with the K&B or will you wait and see how the Nova goes as it is?
I hope that you're going to trim up the bottom of the cowling. We had a guy here in town that designed his own tunnel and it sat real low on the water. It had a bad habit of submarining any time that he hit a wave. Looked cool though, it would go under then pop up and keep on going. ;D
Gene have ya'll tried any semi-symmetrical airfoil shapes on the bottom rear center section ?? Do you think that to offset this shape you would have to drop the front center section to compensate with more down force ??
Ok . It's best to just stick with the flat bottom. What us airplane guys call a Clark Y airfoil. Just keep it thin to keep the lift down so it don't won't to blow off, because you can only move the CG but so far forward, with out adding to much weight.
I was just wondering on this SUNNY no WIND 72* Sunday afternoon!!!! he ! he !! he !!! SORRY GUYS I HAD TO !!!
OK !!! OK !!! A MODIFIED Clark Y !!!!! If you take that picture and take off about 10% off the L.E. and shrink it down until it's about 1/2" thick in the center and 3/8" at the rear, 1/4" in the front, you will have it!!!
But you see from were the bottom spar would be,to the L.E. the bowed shape ?? Move it back toward the T.E. 1" or 2" or more, make it with a longer radius like about half of the top.
Easier yet, look at the side profile of the Villian center section . Now take the top profile ,say 1/3 or less of it and add it to the rear bottom, and let it taper out to the flat bottom. but don't go past the CG, let it blend out flat about the CG. And then drop the front of the center section down a little 1/4" or so, for down force. Less weight in the sponson tips. Picking up the rear and pushing down on the nose. :
JUST A BRAIN FART !!! KIND'A THING !!!!! :-[ :-[ GENE, QUIT THAT **** LAUGHING !!!! U'LL P YOUR PANTS !!!
Nah really if ya want to try out your ideas, and build ya up some WOF center sections, slap on a set of modified Sprint sponsons, like out from 24" to 27" Ya never know!!!! I got a set of Dumas Sprint plans I can send ya, if ya want ta give it a go, I have scribeled a bit on them but they are complete.
