No problem Catfish I hear what your saying. I actually agree with what your saying. I find now that because I have raised the prop shaft, that alone has made it so I require less trim. I now don't believe having the setback was the issue I was having before. I screwed up in my measuring and if I'm at 12 now moved in I was 13+ before but I was also below the pad some were? That is the reason I believe now that I required so much trim to get the speed I needed to get with the power and props I ran before... I'm getting faster speeds now with less pitch and less trim even to above lipless.{not by choice, but I like how she feels lipless}. So if I had the ability to raise my motor like I can now at farther back I would have required less trim then also. I was buried like 1/2-1/4 below at the highest point on the jack. I think that with a lip you dont have to run as high a prop shaft hight to get the right aditude as without the lip? So were we can run with out a lip and less trim is mainly because the lip isnt there to help? Guys are running at Nutralish trim with a lip 106 at 1/8 and 1/4 above some even with the pad. To run 106 lipless with the same amount of trim do you think lipless would need to run a higher propshaft hight like 3/4 above? Thats what I ment. I have heard that to run more than this there have been guys that do believe on some models like yours and mine that the lip does make running extreem speeds above were the hulls were designed to run could do so with the lip shaved or gone. Trim aside the higher ya go with the propshaft the less trim will be required for sure. Well ya hope so because the trim would naturally start being very limitted in travel due to the diamiter of the blades and the greacases design to the pont of blow out very sortly on the possitive side the higher ya go. What I ment in that quote was when I had the shotbags all far forward I needed more trim than when I moved some farther back the other day. So with less power I believe that the placment of the Offset depending on how much you weigh should be placed so you dont need more trim to carry the bow the ideal way. If it was all say right forward you would need more trim to carry the bow. With no lip you would also need a higher propshaft hight. So finding that balance with the right hight the right amount of offset for your weight and the placment off the offset for your power suply all are factors in getting the most out of a setup I think.
When you have weight like shot bags far forward to carry the bow you'll need more trim to keep the bow up than if the weight was farther back in the gunnel unless you have the power to carry that extra weight. Sorta like the flighty feel you XB guys talk about when you take the troller off the bow. At speed you probably require less trim? The lip from what I understand lifts the stern not the bow so the whole hull. Not so much forcing down the bow but enabling the whole hull to fly more level at just past Neutral with an ideal setup cutting the aerodynamic, coefficient effect more ideal by design. With different weighted drivers the amount of offset will be less for lighter drivers. This will intern change the total force required to carry the hull level from the thrust of the propeller. The placement of the offset has an effect on this also as Jeff mentioned. So if your a heavier guy with more offset shot bags, more setback than a lighter guy should help theoretically.:big grin Hence because of the more weight forward and total hull XB03,s have generally as a rule XB03,s use more setback on 90% of setups over XS hulls. Jeffs used his hull for Drag racing and has an SS motor. Theres setback built into the 15 inchers over the 20,s. So with his lighter driver weight, side steer mods,less offset, and less setback with an ss motor his setup is fine turned for him. Less setback some say is best for faster hole shots hence the drag setup or best of both worlds Jeff has with his 260 by what speeds he gets. I think with jas setup and a 225 he is setup in the right spot, just a little more offset stragicly placed and run even to the pad and good to go. I was actually getting mixed up thinking Jas had the 340 HP JSRE 260 when its American.:banghead With more power you can get away with all the weight forward with the offset because of the thrust difference between a 225 and a 260 setup. I needed to get a little of my offset back a little from all forward with the 225 to be able to use less trim. I'm pretty well balanced now and with the higher prop shaft heights and my weight 225lbs forward as well as the 60-70lbs of offset placed all down the left side from the Glove box to the stern She flys real nice and level with very little trim at even and 1/4 above with a 225 lipless.
