oh, and offset is at 2" center to center..played with it out farther, but didn't like it..as I said, just a small tweak to tunnel and test..then will go back for final mold..boat is very close to exactly what I want
major mods to motley crew

I have a 29" Mean Machine that is built for twins with 3 1/4" stingers.
It has a tunnel wider then most.(5 3/4")
I put a longer (farther back) rudder on it, but I think it needs to farther back some more.
Right now the leading edge is at the front of the prop, I would like to move it back an other 3/4" to the rear of the prop.

Steering and handling at Speed --- The longer rudder standoff has helped a lot, I will extend it an other 3/4" to put the leading edge at the rear of the props.
My other choice is shorten the stingers a bit.
I want to run this in "P" Offshore (NAMBA)
Right now I have a pair of 3674 - 1700Kv in it for Offshore
I am getting 4:30 to 5:00 min. of run time on 10,000mA
I have a pair of 3674 - 2200Kv to run in "P" Cat
Terry- That was my Offshore setup.

MY MM cat
Since these pictures were taken.
The sponsons have been blueprinted, and I reversed the props ,(they now turn outward instead of inward.)
These two things helped a lot, the boat is now drivable at speed.
I am going to extend the rudder mount an other 3/4" just to make it even better,
especially when I put the 2200Kv motors in it.
The ESC's and motors are wired in such a way that they both see 4S2P instead of 4S1P per motor.

A pair of 90mm EDF -Jet motors ; Tacon - LBP 3674 - 2Y - 1700Kv and a pair of 442 props
And GOOD batteries
Packs are down to about 20% after an Offshore run = about 60 to 65 AMP's average per motor.
Now with the 3674 - 2200Kv motors and bigger props is a hole different story! I have only got to run for under 2 min. ("P" Cat, 1 mile race - 6 laps on the 1/6 coarse)
