Tony,

You may find that moutning/installing the controller infront of the motor on the other side of the motor mount and rotating the batteries (all connections forward) might be easier to manage. You will end up moving the batteries forward before you move them rearward.

Later,
Mike

Thanks Mike - I'll give it some thought - I just took the easy way out with the speedy location - I also have a stock 60A AQ speedy I might put in- they have always worked really well 'tho these setups routinley pull 80A + yet the AQ 60A seems to handle it.

Set the hull up on the loose side (lighter weight lipos mounted more rearward and strut angle/depth) for max speed and less strain on motor using the higher kv 2030 motor. Per Grimracer

Tony,

Keep us posted on your progress. It’s fun to see and hear about the boat in use.

As you all know we had the 2030 out on the market before the Motley Crew. During testing I was just not all that happy with the current draw with the 2030 in the crew. Sure it would have worked but I wanted just a tick more run time and a little less current draw.

I messed with props and started testing the new 1800 we had been working on in the boat.. BINGO.. just right.. A great balance of speed, power and power consumption.

I have quite a bit of data logged regarding the testing of the boat.. fun to look back at all the hours of design and testing that went into that boat.

BTY.. EVERY ASPECT of the hull and hardware were designed and tested here in the US BY ME.. no pulling the wool over the eyes of anybody.. If it sucks.. I TAKE FULL RESPONSIBLITY.. if its fantastic.. the same.. No pointing fingers or any of that BS..
To bring it to market however adds a ton more people..

Have fun with the boat tony!.. love the tip paint!

Mike,

Thanks for chiming in, always good to hear from you. I figured that the decision to use the 1800 motor in production versions was to afford the sport boaters less amp draw/more run time with the ability to experiment with prop options and stay in the safe zone. For sprints the 2030 with the right prop should be the ticket.

I'm really jazzed to finally get a MC - It just lights up my workbench. Like my first UL-1, I know I'll get max use/grins from this boat.

BTW FE Nat's June 6/19 - 6/23 at Legg Lake

Two Words, Bro : ROAD TRIP

Take care!

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

More mods

I didn't like the sound of the stock driveline - seemed to have some buzz, so I replaced flex with an Octura .150 and installed lead-teflon bushings in place of the brass bushing. Some may argue with this, but I run lead-teflon in nearly all of my non-stinger struts and they're ultra-smooth and easy to replace.

I re-did the servo linkage to make it easier to adjust center point and reduced the rudder throw ratio - helps calm down straightline jittering (which is more my fault than the boats)

Now that I can count on the cooling system, I hope to find a few more mph. We'll see.

She sure is purdy :

Tony.. looked stuck.. the RPMs seemed a tick off too.. make sure you round the bottom of the rudder blade.

Cool vid! Did you see the one I did for Scott Roman.. allbeit all stock its really running well.

Here it is

Tony... when you say "teflon"... you mean LEAD-Teflon, right?? You aren't running straight Teflon bushings, are you??

Mike, thanks for the feedback; I agree with you on both points. I need to play with strut height/angle and CG to loosen things up a bit - the run in the vid was on glassy water and I've found that stepped sponsons like granular water to break loose. I'm setting up for the cat sprint class so If I loosen up too much for smooth play water I may go too far in that direction.

Also, I'll be trying my favorite "spec" prop, the Grim 42/55. The M445 loads more than I like on this hull (so far as I can tell). In addition, my "seat of the pants" (and ear) impressions tell me that the stock AQ speedy works best with this motor so I'm switching back to it as well.

I'm really impresed with this boat, visually it's killer, and needs NO mods out of the box for max use ( I'm a compulsive modder, so what I've done is unneccesary for most users). A really important side benefit I've found for efforts to promote and introduce FE to the general public is the fact that when a Father and Son come up to my table at the lake and ask about dollar investment, instead of pointing (and wincing) to my purpose-built raceboats, and explaining the cost, which will scare away most Dads , I can show that a totally cool boat like the MC can be had without breaking the bank.

More to come
