Finally scored one- setting up for NAMBA P-Ltd Cat Sprint race
Now that there'll be a P-Ltd Cat Sprint class at the FE Nat's this June, I've been experimenting. I set up a MM with a 2030KV AQ; runs 45mph with a M445 (& cooling fan on motor). Runs & handles very well but I picked up a used MC in the swap. After hearing of some production flaws I was apprehensive, but this one is el perfecto beautiful. I had my choice of dropping in the 1800KV AQ motor, but I'm starting out with the 2030 to see if she'll hold sprint race time. Probably begin with the 42/55 but since the MM held the M445 I may give it a cautious try as well with the 2030.
Glassed the inside of the hatch. Put in a UL-1 rudder and opened up the water inlet some.Had a spare FCR 140A speedy so dropped it in. Has stock flex; tinned the end but will be ordering an upgrade shaft (what's up with the stock shaft ? - heard it has issues) One sponson tip had a slight crunch so a little Formula27 & red tips now. Sponson bottoms not too bad; might blueprint some. Set strut @ 3/32" & level to start.
Comments/advice welcomed. Will vid & post soon.

First run Video & Modifications
First test on smooth water. Run #1 she bobbed some; moved batt's forward to motor mount & adjusted strut to point nose down a tad. Ran Wet. Moved batt's back @ 2/12" & ran really nice. Hull runs really wet in turns (like gas cats). Did 45.7 mph compared with exact setup on Mean Machine which ran 44.4 (M445) ( I noticed the cooling lines were dry on the first two runs, this run they had water in them-more on that to follow)

I decided that the rudder pickup (rudder from UL-1) was high; I lowered it, installed larger diameter cooling lines, and moved the outlet to the side so I can see output better. [If you want to know how I got the larger diameter hose through the transom & hull side holes, It'll cost 'ya :wink:]

Pretty sure I found the "sweet spot"
By applying ancient Oriental practice of "Too-ning" (taught to me by Masters Darin-San and Brian-San) got first number on GPS to read "5" :banana: (other number not to be revealed because of secret pact with underground Spirit :wink:).
