Ok, so I got my x642 in the mail from OSE today, and went out to try it out on my usual set of 4s speed-test batteries. Much to my dismay, it ran the same ~31mph that I'm getting on the stock prop on the same set of batteries. The water today was much more smooth than it was yesterday when I hit ~31mph on 4s with the stock unbalanced prop.
Boat is setup as follows:
CG ~8.875" from transom
stock hull, stock motor/ESC/battery connectors
5.5 bullets from motor to ESC
sharpened & balanced x642
OSE flex (freshly greased before the run today)
OSE fins
Speed master tabs
Strut angle ~1/2 deg neg
tabs are ~1.25deg (left) and ~1.5deg (right)
strut height .220" above keel
batteries are dynamite "reaction", 5000mAh, 30c, with ~10 cycles on them
Temps were 115 motor, 90 ESC, 120 batts, 160 connectors (both esc/motor and batteries).
Boat was nice and stable in the water.
What the heck am I doing wrong? All I can think of is that the boat is running too wet, but I'm not sure what else to do to get the boat further out of the water (I already moved the strut height down substantially).
Aside from batteries, I don't have any spare parts to start swapping to see if there's a power system issue.
