Ok so i have a problem had my spartan for 1 year now ran good for 4 months then i upgraded a few bits
and runs not as stable also not as quick of the mark anymore

running
lepoard x2 1600kv
seaking 180amp 15 deg timing
x2 3s hyperion graphine lipos 5200mah 90c
prop 44mm 1.6 pitch brass

dual pick up rudder,stinger,dual tabs all rc boat bitz stuff
new flex shaft upgrade .187 teflon line and new brass


this boat stock was great has awesome take off and turning pretty stable with little to no chine walk

now i have massive cavatation at hole shot and cornering its like a slingshot till it get up onto plane then shes away
temps are good still on everything

stinger is set at 0 line from v in hull
trim tabs flush of the rear

any ideas to what be happening i have tryed a 42mm 1.6 pitch prop also played with the stinger angle down 3-4mm from centre dont what else to try to get this thing as zappy as it used to be before the motor and esc change


cheers
