delta 26" neu 1515 1y or 8xl

[Chuck E Cheese]

i am looking for someone who has built a delta 26" with a 8xl or 1515 1y. i was getting ready to build one and needed information on the set-up, hoping someone could share. the set-up i want is:

feigao 8xl, cc120, 2x 4s - 2700 - 30c, x440 - 642
or
neu 1515 1y, cc240, 2x 4s - 5000 - 25c, x440-642

i am looking to make this boat run solid 50mph. i was looking for pictures of someone who has a 26" with XL motor. what i need to know is how they set-up the motor / battery and COG. i am using speedmaster strut/rudder. info like the cog, distance from front motor endbell to transom, battery and esc placement. i wasnt going to install rails but could if necessary.

1) batteries in the center? front or rear or sides (5000mah 4 cells hard to fit on the sides)

2) distance to the front of the motor

3) cog % (25-35?)

4) motor - esc - prop combo

pictures would be greatly appreciated....
please no set-up other than XL or 1515 4 cells, i already have one that runs 8l on 3 cells and a SV/ammo set-up and those boats work great. even though speed is similar i have these motors and esc's and want to put them in this hull...

Neu all the way.

Batteries where they need to be to make the CG.

Motor location depends on whether you use a wire drive [motor all the way forward] or a flex cable [around the middle of the hatch area].

i use a .187 flex on allmost all my boats.
